First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed at an inner region of the mobile terminal covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the electric field according to the proximity of the conductive object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch.

Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

As such, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and then transmits the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different control or perform the same control according to the type of touch object that touches the touch screen (or a touch key provided in addition to the touch screen).

On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

On the other hand, the camera 121, which has been described as the configuration of the input unit 120, includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention.

As multimedia functions become more important, the wireless communication technology performed by the mobile terminal 100 may be performed in various forms such as short distance, long distance, or between devices. Since different frequency bands (resonant frequencies) are used, different antennas must be used. do.

In order to support the transmission and reception of a large amount of data, LTE (4th generation mobile communication), the 4th generation mobile communication technology, has emerged.However, considering the trend of users consuming data and the spread of the Internet of Things, LTE data is faster than LTE. There is a need for an ultra-wideband mobile communication technology capable of transmitting and receiving. Fifth generation mobile communication technology is being developed. Wireless technology for 5G mobile communication is called NR (New Radio) in 3GPP (3rd Generation Partnership Project), and International Telecommunications Union (ITU) is called International Mobile Telecommunication (IMT-20-2020). It is a communication method implemented by the method.

In addition to transmitting fast and large amounts of data through 5G mobile communication, the reliability of data transmission may be improved and a function of supporting IoT may be added according to the spread of the Internet of Things (IOT).

5G is a mobile communication technology with a maximum download speed of 20Gbps and a minimum download speed of 100Mbps. In addition, the Internet of Things (IoT) service can be provided to a million devices within a 1㎢ radius, and free communication is possible even at a high speed train of 500 km per hour. The download speed is 280 times faster than LTE. It is a wireless communication technology that can download a 1GB movie in 10 seconds.

5G mobile communication has noticeably improved response speed as well as transmission speed. If the data transfer rate is an indicator of how much data can pass through at one time, the response rate determines how long it takes for small data to travel.

At 4G, the response speed is up to 10-50ms (milliseconds, milliseconds). At 5G, this response is about 10 times faster. Thanks to this, 5G will be actively introduced in the fields of autonomous vehicles and the Internet of Things (IoT), where a large amount of data must be seamlessly exchanged with a central server.

Frequency bands of the centimeter wave (3 GHz to 30 GHz) and the millimeter wave (30 GHz to 300 GHz) may be used, and a communication method using a signal of a frequency band below 6 GHz is particularly called Sub-6.

Sub-6 includes N41 using the signal band of 2.5GHz to 2.7GHz and N78 using the signal band of 3.3GHz and 3.8GHz and below, and the frequency band used may vary from country to country. For products with specifications available around the world, antennas are needed that achieve performance in both frequency bands.

2 is a view for explaining the arrangement of the LTE antenna and the fifth generation (5G) antenna of the mobile terminal according to the present invention. The existing LTE antenna has been improved several times, and the structure of the antenna is complicated. For broadband LTE, an antenna structure capable of extending a bandwidth at a resonant frequency is required, and a signal of another frequency band may be received for LTE-Advenced (LTE-A) using signals of several frequency bands instead of one frequency band. There is a need for a plurality of antennas or antennas capable of multi-resonance.

A plurality of antennas are used to cover all signals such as a frequency band below 1 GHz (low band) and a signal around 2 GHz (mid band) and a frequency band above 2.2 GHz (high band). It is necessary to provide.

In addition, a plurality of antennas are required to apply a multiple input multiple output (MIMO) technique. Multi-input / output method has two or more antennas in the base station and the mobile terminal to transmit data through several paths, and detects it at the receiving end to reduce interference and lower each transmission rate. Can transmit Figure 2 (a) shows the antenna structure when using the 4x4 MIMO scheme for LTE mobile communication, four antennas are required and all four antennas can be received (Rx.), But one antenna capable of transmitting Dogs.

Since the antenna for transmission is more sensitive to interference than the antenna for reception, it is generally located in a position that minimizes interference with other electronic components. It is electrically connected to a wireless communication unit for LTE communication can transmit or receive a signal corresponding to the resonance frequency of each antenna.

As described above, only four antennas for improved LTE mobile communication may be applied, and additionally, antennas for wireless communication such as WIFI, Bluetooth, and GPS may be additionally provided.

Even if the mobile communication method using 5G mobile communication is put into practical use, 5G communication is limited due to the lack of facilities for 5G communication and existing terminals cannot perform 5G communication. The terminal also needs a mobile terminal that can use both methods.

FIG. 2B is a conceptual diagram of a mobile terminal having an antenna and a wireless communication unit for further using the N78 signal in the structure of FIG. A first wireless communication unit 110a for 5G wireless communication and a second wireless communication unit 110b for LTE communication are provided, respectively, and the first wireless communication unit 110a and the second wireless communication unit 110b are main chipsets. It may be mounted on the substrate 181 (see FIG. 3). A circuit on the main board 181 and a signal line connected to the main board 181 may be used to connect each antenna to the wireless communication units 110a and 110b.

Since N78 uses signals of about 3.5GHz band, it uses signals of different bands from existing LTE. Since there is little mutual interference, 5G mobile communication and LTE communication are possible using one antenna. That is, each antenna is connected to the first wireless communication unit 110a and the second wireless communication unit 110b at the same time, and the antennas connected to the first wireless communication unit 110a and the second wireless communication unit 110b at the same time are called common antennas. Additional conductive patterns can be tuned for use in both frequency bands.

Figure 2 (c) shows the arrangement of the wireless communication unit and antenna for performing wireless communication using the signal of N41 by using the antenna for LTE. The antenna of this embodiment has five antennas unlike the above-described embodiment. A first wireless communication unit 110a for 5G wireless communication and a second wireless communication unit 110b for LTE communication are provided, respectively, and three antennas are provided in the first wireless communication unit 110a and the second wireless communication unit 110b. There are antennas connected at the same time but connected only to the first wireless communication unit 110a and only to the second wireless communication unit 110b.

Since the signal of the N41 uses a signal band of 2.7 GHz, a section overlapping with the signal of the B41 (2.5 GHz) band of LTE may occur and interference may occur. The receiving antenna may be used together for the signal of the N41 band and the signal of the B41 band, but the transmitting antenna has an independent antenna connected only to the first wireless communication unit 110a when an interference occurs. can do. For convenience of description, a signal used for wireless communication through the first wireless communication unit 110a is a first signal (LTE signal) and a signal used for wireless communication through the second wireless communication unit 110b is a second signal (5G signal). Is called.

Hereinafter, an antenna applied to an actual mobile terminal will be described in detail. 3 is a diagram illustrating an embodiment of an antenna arrangement of the mobile terminal 100 according to the present invention, and illustrates an antenna connected to the first wireless communication unit 110a.

The mobile terminal 100 divides and uses a space because various components are mounted in a limited space, and the battery which occupies the most volume is disposed on one side and utilizes the remaining space to the main board 181, the camera 121, and the sound. Various components such as the output unit 152 and the interface unit 160 are mounted.

Recently, a mobile terminal adopts a design for implementing a side case 210 positioned at a side using a metal material. The structure of the side of the mobile terminal made of metal may be excellent in terms of design, but the components inside the mobile terminal 100 are surrounded by metal, and in particular, the antenna is a device made of a bar metal material that uses electromagnetic waves. There is a problem that communication performance is degraded.

When the problem is solved, the metal part of the side of the mobile terminal itself may be used as an antenna in order to secure an antenna arrangement space in the mobile terminal 100. As shown in FIG. 3A, the mobile terminal 100 includes a side part 210 that is integrally formed with a support part 230 positioned on a rear surface of the display part to support the display part 151 and reinforce the rigidity of the mobile terminal. The middle frame 200 may be used. In other words, the side case is integrally formed with the support part positioned on the rear surface of the display.

The middle frame 200 includes a conductive material such as magnesium or aluminum, and has a predetermined rigidity to reinforce the rigidity of the mobile terminal. The support 230 is a conductive material having the largest size in the mobile terminal, and can serve as a ground, thereby enabling grounding through the support 230. The side part 210 may be spaced apart from the support part 230 and partially connected to the support part 230. In order to use the side part 210 as an antenna, the side part 210 may be divided into a slit 220 to be divided into a plurality of conductive members. The conductive member may be connected to the ground of the support 230 or the main substrate 181 and grounded, and may be used as an antenna for receiving a signal by receiving power through a power supply line 182 (see FIG. 4).

In order to implement a plurality of antennas for transmitting and receiving a first signal and a second signal, a plurality of conductive members are required, and the slits may include at least four or more slits.

The antenna must be formed to be 1/2 or 1/4 times the frequency of the communication signal to resonate with the signal to be received. The end of the antenna may be determined by connecting to the support 230 or the ground to ground or to partition the slit 220. When both ends of the antenna are connected to the support 230 or to the ground of the main board 181, both ends are grounded to implement a closed slot antenna. When one end of the antenna is grounded and the other end is opened to the slit 220, an open slot antenna having one side may be implemented.

The closed slot antenna may have a length corresponding to one-half wavelength of the signal to be received, and the slot antenna having one side open may have a length corresponding to one-quarter wavelength of the signal. The open slot antenna may have a shorter antenna length than the closed slot antenna, and one side of the open slot antenna may be easily tuned to facilitate an antenna having a multi-resonant frequency.

Although the side part 210 functions as an antenna functionally, but constitutes a part of the appearance of the mobile terminal, it is limited in design. In consideration of the wavelength of the received signal, it is difficult to form the slit freely, and the number of slits 220 is also limited due to the design characteristics. The side part 210 of the mobile terminal illustrated in FIG. 3 has two slits 220 at the top, two slits 220 at the bottom, and one slit 220 at the side. The space between the side part 210 and the support part 210 and the slit 220 may be filled with the injection material 240 which is a non-conductive material.

This embodiment includes an independent antenna connected only to the first wireless communication unit 110a and a common antenna simultaneously connected to the first wireless communication unit 110a and the second wireless communication unit 110b. Since the conventional antenna for LTE communication is located on the upper and lower sides of the mobile terminal, independent antennas Ant1, Ant2, and Ant4 may be additionally formed on the side of the mobile terminal 100.

4 is a view showing an embodiment of an independent antenna of the mobile terminal 100 according to the present invention. FIG. 4 (a) shows a power supply line electrically connected to the middle frame 200 and the first antenna Ant1. 4 is a conceptual view illustrating the arrangement of 182, and FIG. 4B is a cross-sectional view of a portion of the first antenna Ant1.

Referring to FIG. 4A, the first antenna Ant1 of the present embodiment is a slot antenna with both ends closed. The length of the slot antenna, which is closed at both ends, may have a length corresponding to 1/2 of the wavelength length λ of the received signal, and may be affected by the influence of peripheral components and the slot 245 between the 230 and the side portion 210. It may vary depending on the dielectric constant of the injection material 240 to be filled.

The feed line 182 supplied from the first wireless communication unit 110a is spaced apart from each other without being directly connected to the side portion 210 as illustrated in FIGS. 4A and 4B to feed power in a coupling manner. can do. Although the power supply line 182 is not directly connected to the first antenna Ant1, a current flows in the first antenna Ant1 due to the electric field formed by the power supply line 182, thereby supplying power. The slot antenna, which is closed at both sides, is precisely divided in length so that more stable wireless communication is possible than the slot antenna at which one side is open, and thus the coupling type feeding can be adopted.

As shown in (b) of FIG. 4, the coupling method is sufficient to be disposed in contact with the inner surface of the injection-molded product 240 filled in the slot, and a connection structure that directly contacts the side portion 210 (for example, the C clip 184). 5, etc.), may be omitted, and the number of members may be reduced, and space may be easily secured.

The first wireless communication unit 110a of the present embodiment may transmit and receive signals in the N78 frequency band (3.5 GHz band). Since the wavelength of the N78 band is shorter than the wavelength of the N41 frequency band, the length of the antenna can be shortened. As shown in FIG. 3, two antennas Ant1 and An4 can be arranged side by side.

5 is a diagram illustrating a common antenna of the mobile terminal 100 according to the present invention and corresponds to the third antenna Ant3 of FIG. 3. The common antenna of the present embodiment may have a form of an open slot antenna having one end open. As described above, the slot antenna having one side open is easily tuned to an antenna having a multi-resonant frequency, and thus the common antenna may be formed in the form of an open slot antenna, that is, a slit 220 formed at one side. A slot antenna having one side open may use an antenna having a length corresponding to 1/4 of a wavelength length λ of a signal to be received, but the mounting space may be reduced, but the slit 220 may be formed on the side portion 210. There is a problem affecting the appearance design because it must be formed. Therefore, the slot antenna of one side of the open shape can be limited to the position where the slit 220 is formed.

Since the slot antenna having one side open is less stable than the closed slot antenna, it is possible to use a direct feeding method for feeding power through a conductive wire in contact with the side part 2210. As shown in (b) of FIG. 5, the connection clip 184 may be mounted on the injection molding 240 to contact the conductive member of the feed line 182 and the side part 210 through the connection clip 184. .

The feeding line 182 feeding the antenna may be implemented by forming a pattern on the rear case 102 as shown in FIGS. 5B and 4B.

3 is provided with three slits 220 at four lower portions of an upper portion of the mobile terminal 100, so that the side portion 210 can be divided into several conductive members. Therefore, the section in which the side portion 210 can be utilized as an antenna is increased, so that only one common antenna is provided and the rest can be implemented in the form of an independent antenna. In particular, since the signal of the N78 frequency band has a short wavelength, it is easy to secure an antenna arrangement space inside the mobile terminal 100.

6 is a view showing another embodiment of the antenna arrangement of the mobile terminal 100 according to the present invention. In the present embodiment, the number of the slits 220 is smaller than that of the embodiment of FIG. 3, so that the number of side parts 210 that can be used as an antenna is limited. Accordingly, the number of common antennas capable of receiving both the first signal and the second signal may be larger than that in the embodiment of FIG. 3.

According to the present embodiment, the signals transmitted and received by the first wireless communication unit 110a may include signals of N78 as well as the N41 frequency band. As the frequency band used varies, the number of antennas connected to the first wireless communication unit 110a is increased. May exceed four.

Referring to FIG. 6, the common antenna of the present embodiment may include second antennas Ant2 to sixth antennas Ant2 to Ant6. The common antenna may receive a signal of the N41 band or the first signal of the N78 band and transmit the received signal to the first wireless communication unit 110a. Also, the common antenna may receive and transmit the second signal to the second wireless communication unit 110b. Since the fifth antenna Ant5 does not transmit the signal of the LTE B41 band, the fifth antenna Ant5 may be responsible for the transmission (Tx) of the N41 band signal of the second signal as well as the first signal.

In the present exemplary embodiment, the independent antenna lacks the number of antennas for receiving the first signal as one of the first antennas Ant1. The antenna may further include a pattern antenna Ant7 implemented by adding the conductive pattern 116 to additionally implement the antenna for receiving the first signal.

The pattern antenna may be formed on the inner surface of the rear case 102 of the mobile terminal 100, printed on the antenna carrier with a conductive material, or attached using a flexible substrate. One side of the conductive pattern 116 may be implemented as an inverted F antenna (IFA) connected to the middle frame 200 and grounded, and the power supply line 182 is connected to receive power. The pattern antenna may have a length corresponding to one quarter of the wavelength of the N78 signal to receive a signal in the N78 frequency band.

In order to receive a signal through the pattern antenna Ant7, an open space not surrounded by a conductive material is required. Since the side part 210 is located in the side direction of the mobile terminal 100 and the support part 230 or the display part 151 is located in the front direction of the mobile terminal 100, the antenna has difficulty in radiation. Accordingly, the pattern antenna Ant7 according to the present embodiment may implement an open space through which a signal can pass by utilizing a structure for a side button 123b (see FIG. 1B) as a user input unit located on the side of the mobile terminal 100. .

The side button 123b includes a switch substrate including a top button exposed to the outside of the side and a dome switch generating a signal when the top button is pressed. The top button may be inserted through the button hole 241 formed in the side part 210, and the switch substrate may be inserted by forming a button gap 243 between the side part 210 and the support part 230.

The button hole 241 is positioned in the lateral direction of the pattern antenna Ant7 and the button gap 243 is located in the front direction of the pattern antenna to secure a space in which the conductive material is partially removed. Can send and receive

7, 8, and 10 illustrate another embodiment of the antenna arrangement of the mobile terminal 100 according to the present invention. The mobile terminal 100 of the present embodiment further includes an antenna capable of receiving a signal of millimeter wave (mmWave) as well as an antenna for sub-6 bands N41 and N78, and includes LTE, sub-6, and millimeter wave. It is possible to perform a variety of mobile communication. The millimeter wave uses a very high frequency signal having a short wavelength in mm units, and the length of the wavelength can be shortened, so that the size of the antenna can be reduced. Using very high frequency signals, the frequency band can be widened to increase data rates and transmission rates.

As the antenna used in the conventional mobile communication, an antenna having a radiation pattern in which electromagnetic waves are radiated while being directionally spread like a dipole antenna or a monopole antenna is used. However, in this case, since a lot of energy is consumed in signal transmission, the gain is lowered. Thus, the transmitter can perform mobile communication with less energy by using a beam pattern radiation method that emits toward the receiver.

The beam pattern of each antenna may be combined using a plurality of radiation elements to implement a sharp beam pattern. An array antenna using a plurality of radiating elements may make a beam pattern sharper and transmit a signal farther in a specific direction. The direction of the beam pattern may be adjusted by adjusting the power supplied to the plurality of radiating elements.

If the millimeter wave antenna 119 is also disposed adjacent to other antennas, the performance may be deteriorated. The part where the millimeter wave antenna 119 is disposed and the first radio communication unit 110a or the second radio communication unit 110b The connected antennas may be arranged so as not to overlap. That is, the side portion 210 where the millimeter wave antenna 119 is located may be omitted, and the omitted side portion 210 may not be used as a sub-6 antenna or an LTE antenna, and thus may be used as an antenna. The number of side parts 210 is reduced.

In the embodiment shown in Figure 7, the millimeter wave antenna 119 is located on the upper side of the mobile terminal 100, an embodiment in which the side portion 210 of the upper side is omitted. FIG. 7A illustrates a case in which the slit 220 is located at the upper left side of the drawing, and (b) illustrates the arrangement of the antenna when the number of slits 220 is further reduced by deleting the slit 220 at the upper left side. Illustrated. As described above, when the number of slits 220 decreases, the space for using the side portion 210 as an antenna is reduced, and thus it is necessary to implement the antenna using a member other than the side portion 210 as in the pattern form.

In the embodiment of FIG. 7A, the first antenna Ant1 to the third antenna Ant3 do not have the millimeter wave antenna 119 (see the embodiment of FIG. 3). Can be implemented using This embodiment has an antenna capable of receiving signals in the N41 band, and the length of the antenna for the N41 band should be longer than the length of the antenna for the N78, so that two terminals are simultaneously arranged on one side of the mobile terminal 100. It is difficult. Therefore, in the present embodiment, it is possible to arrange the antenna at another position or use another type of antenna such as a pattern antenna.

As shown in FIG. 7A, the pattern antenna Ant4 may be formed by forming the conductive pattern 117 on the rear case, the substrate, or the antenna carrier. The pattern antenna Ant4 may be driven by an independent antenna connected to the first wireless communication unit 110a, and the side part 210 is partially omitted for the millimeter wave antenna 119 on the mobile terminal 100. The side portion 210 may be disposed adjacent to the omitted portion to secure antenna performance.

When the slit 220 is omitted as shown in FIG. 7B, the second antenna Ant2-1 is moved upward, thereby causing interference with the fourth antenna Ant4, and the second wireless communication unit 110b. It is integrated with the antenna for the common antenna. Common antennas may have difficulty in terms of performance and implementation because they need to implement a multi-resonant structure having two or more resonant frequencies in terms of performance than independent antennas. In this case, the second antenna may be implemented by moving to a different position in the form of pattern antennas 118 and Ant2-2.

FIG. 8 illustrates a case in which the millimeter wave antenna 119 is located at the side of the mobile terminal 100. As shown in FIG. 7, the first to third antennas Ant1 to Ant3 may be similarly implemented. However, unlike the embodiment of FIG. 7, since the side portion 210 of the upper portion of the mobile terminal 100 exists, the pattern antenna Ant4 of FIG. 7 is difficult to use.

Instead, as shown in FIG. 8A, a pattern antenna Ant 4-1 emitting by using the button hole 243 and the button gap 243 of the side button 123b may be used. Since the pattern antenna using the button hole 243 and the button gap 243 has a structure similar to that of the pattern antenna Ant 4-1 of FIG. 6, the detailed description is replaced with the above description.

 However, the pattern antenna Ana4 must separately add an antenna structure, and may use side parts 210 and Ant4-2 at the bottom of the mobile terminal 100, as shown in (A) of eh 8. However, the lower side part 210 is connected to the second wireless communication unit 110b and is used as an LTE antenna. The first wireless communication unit 110a is not an independent antenna that serves only as an antenna of the first wireless communication unit 110a. ) And the second wireless communication unit 110b may receive both the LTE signal and the 5G signal as a common antenna.

If one of the upper slits 220 is omitted as shown in FIG. 8B, the second antenna Ant2 is used as the common antenna Ant2-1 or the pattern antenna Ant2 as shown in FIG. 7B. -2) can be used.

FIG. 9 (a) is a graph showing the performance of the independent antenna (first antenna Ant1) of FIG. 8 (b), and FIG. 9 (b) shows the common antenna (2-1-1 antenna) of FIG. 8 (b). This is a graph showing the performance of (Ant2-1)), and the part protruding sharply in the downward direction corresponds to the resonance frequency. Independent antennas have a single resonant frequency in the 3.5 GHz band, while common antennas exhibit a resonant frequency in the 1.5 GHz band and over 3 GHz. That is, the common antenna can receive both LTE signals and 5G signals through multi-resonance.

FIG. 10 is a diagram illustrating an arrangement of antennas using the side part 210 when the millimeter wave antenna 119 is positioned below the mobile terminal 100. The lower front surface of the mobile terminal 100 can emit radiation through the space between the display unit 151 and the side portion 210 because the bezel is wider than the side direction between the display unit 151 and the side portion 210. . Therefore, when the millimeter wave antenna 119 is disposed below, it is not necessary to remove the side portion 210.

However, since the millimeter wave antenna 119 is located at the bottom, there is a problem in that the performance of the antenna using the side portion 210 positioned at the lower edge adjacent to the millimeter wave antenna 119 is degraded. As shown in FIG. 2, the side portion 210 positioned upward from the lower slit 220 (located away from the millimeter wave antenna 119) may be used as the antenna Ant 4-3. .

When the number of antennas connected to the second wireless communication unit 110b is insufficient, it may be used as a common antenna, or may be used as an independent antenna for receiving only the first signal through the first wireless communication unit 110a.

As described above, the mobile terminal 100 of the present invention is connected to two or more wireless communication units in a limited area and has a common antenna for receiving different signals, thereby allowing antennas for LTE communication and 5G communication in a limited space. Can be.

The foregoing detailed description should not be construed as limiting in all respects, but should be considered as illustrative.
