In the related art, an antenna switch is generally connected in parallel near the end of an antenna so that the antenna can cover a wider frequency band. However, the voltage at various locations on the antenna is inversely related to the distance from the antenna tip. Referring to fig. 1, fig. 1 is a schematic diagram illustrating a distribution of an antenna voltage according to an exemplary embodiment. Wherein, the distance D is the distance from the terminal of the antenna, and the voltage U is the voltage value corresponding to the distance D. As shown in fig. 1, the closer the antenna is to the tip, the higher the voltage. It can be seen that when the input voltage to the antenna is large, the antenna switch located near the end of the antenna is at risk of being broken down, burned out, or scattered due to overvoltage.
Accordingly, the present disclosure solves the above-mentioned technical problems occurring in the related art by improving an antenna structure.
Referring to fig. 2, fig. 2 is a schematic structural diagram of an antenna structure according to an exemplary embodiment. As shown in fig. 2, the antenna structure 1 of the present disclosure is applied to an electronic device, and may include an antenna 10, an antenna switch 11, and a voltage control module 12; the antenna switch 11 is disposed near the end P of the antenna 10 (connected in parallel near the end P of the antenna 10, and the left end of the antenna 10 in fig. 2 is the end P), and the voltage control module 12 is configured to control the input voltage of the antenna 10, so as to control the voltage of the antenna switch 11 within a safe range. It can be seen that, since the antenna switch 11 is disposed near the end P of the antenna 10, and the voltage near the end P of the antenna 10 is higher than that at other positions, the voltage control module 12 is disposed to control the input voltage of the antenna, so that the voltage on the antenna switch 11 near the end P is within a safe range, and the problems of breakdown, burning out, stray, and the like of the antenna switch 11 due to overvoltage can be prevented. The structure of the voltage control module 12 will be described in detail with reference to the accompanying drawings.
As shown in FIG. 3, the voltage control module 12 may include a voltage detection submodule 121 and a voltage regulation submodule 122. The voltage detection submodule 121 is electrically connected to the antenna 10, and is configured to detect a voltage near the terminal P of the antenna 10; the voltage adjusting sub-module 122 is used for reducing the input voltage of the antenna 10 to make the voltage of the antenna switch 11 within a safe range when the voltage detected by the voltage detecting sub-module 121 exceeds a preset threshold. The voltage detection submodule 121 and the voltage regulation submodule 122 are described in detail below, respectively.
1. Voltage detection submodule 121
The voltage detection sub-module 121 may detect the voltage by using two ways, namely, parallel detection of resistors and direct detection, which are described below.
1) Parallel detection resistor
The voltage detection sub-module 121 may include a detection resistor 1211 and a first voltage detection chip 1212. The detection resistor 1211 is connected in parallel to the vicinity of the end P of the antenna 10; the first voltage detecting chip 1212 is connected in parallel with the detecting resistor 1211 for detecting the voltage of the detecting resistor 1211. Since the detecting resistor 1211 is connected in parallel to the vicinity of the end P of the antenna 10, the voltage of the detecting resistor 1211 reflects the voltage of the antenna 10 in the vicinity of the end P. The detection resistor 1211 may employ a high voltage resistance resistor to prevent the detection resistor from being damaged by a high voltage. For example, 0805 type high withstand voltage resistor can be adopted, and 150V voltage can be borne.
For the specific position of the detection resistor 1211 at the end P, in an embodiment, as shown in fig. 4, one end of the detection resistor 1211 is connected between the antenna switch 11 and the end P of the antenna 10, and the other end is grounded. It can be seen that in the present embodiment, the detection resistor 1211 is closer to the end P than the antenna switch 11, and therefore the voltage on the detection resistor 1211 is slightly larger than the voltage on the antenna switch 11. The preset threshold may be set to a first preset threshold at this time.
In another embodiment, as shown in fig. 5, one end (i.e. the lower end shown in fig. 5) of the detection resistor 1211 is connected to the connection point of the antenna switch 11 and the antenna 10, and the other end is grounded. It can be seen that in the present embodiment, the positions of the detection resistor 1211 and the antenna switch 11 connected to the antenna 10 are the same, so that the voltage across the detection resistor 1211 is equal to the voltage across the antenna switch 11. The preset threshold may be set to a second preset threshold at this time.
In yet another embodiment, as shown in fig. 6, one end (i.e. the upper end shown in fig. 6) of the detection resistor 1211 is connected to the vicinity of the connection point of the antenna switch 11 and the antenna 10, and is farther away from the end P of the antenna 10 than the connection point, and the other end is grounded. It can be seen that the antenna switch 11 is closer to the end P than the detection resistor 1211, and therefore the voltage across the detection resistor 1211 is slightly smaller than the voltage across the antenna switch 11. The preset threshold may be set to a third preset threshold at this time.
The values of the first preset threshold, the second preset threshold, and the third preset threshold may refer to the safety range of the antenna switch 11. Based on the position of the detection resistor 1211 shown in fig. 4-6, the magnitude relationship among the first preset threshold, the second preset threshold, and the third preset threshold may be set as: first preset threshold > second preset threshold > third preset threshold. For example, assume that the safe range of the voltage on the antenna switch 11 is 0-80V. Then, since the voltage across the detection resistor 1211 is slightly larger than the voltage across the antenna switch 11 in fig. 4, in order to ensure that the voltage across the antenna switch 11 is within a safe range, the first preset threshold may be set to be larger than 80V, for example, the first preset threshold is 90V; since the voltage across the detection resistor 1211 is equal to the voltage across the antenna switch 11 in fig. 5, in order to ensure that the voltage across the antenna switch 11 is within the safe range, the second preset threshold may be set equal to 80V; since the voltage across the detection resistor 1211 is slightly smaller than the voltage across the antenna switch 11 in fig. 6, in order to ensure that the voltage across the antenna switch 11 is within a safe range, the third preset threshold may be set to be less than 80V, for example, the third preset threshold is 70V. Of course, the specific values of the first preset threshold, the second preset threshold, and the third preset threshold may be flexibly set according to actual conditions, as long as the voltage on the antenna switch 11 is ensured within a safe range, which is not limited by the present disclosure.
2) Direct detection
The antenna structure of the present disclosure may also directly detect the voltage across the antenna switch 11 through the second voltage detection chip. As an exemplary embodiment, the voltage detection sub-module 121 may include a second voltage detection chip 1213. As shown in fig. 7, the second voltage detecting chip 1213 is connected in parallel to the antenna switch 11 for detecting the voltage of the antenna switch 11. When the voltage detected by the second voltage detecting chip 1213 exceeds a preset threshold, the voltage adjusting sub-module 122 decreases the input voltage of the antenna 10 to bring the voltage of the antenna switch 11 within a safe range. In this embodiment, the value of the preset threshold may refer to the safety range of the antenna switch 11. For example, assume that the safe range of the voltage on the antenna switch 11 is 0-80V. Then, the preset threshold may be set to 80V, or less than 80V.
In the present specification, the specific distance "near the end P" may be flexibly set according to actual conditions, and the present disclosure does not limit this.
2. Voltage regulation submodule 122
As shown in fig. 4-7, the voltage regulation submodule 122 may include a modem (modem)1221 and a processor 1222. The modem 1221 is used to adjust input power for the antenna 10; the processor 1221 is configured to control the modem 1221 to decrease the input power to the antenna 10 to decrease the input voltage of the antenna 10 if the voltage detected by the voltage detection sub-module 12 exceeds a preset threshold. For example, as shown in fig. 4-7, taking an IFA antenna as an example, the processor 1221 is a Central Processing Unit (CPU) of an electronic device, the feeding point 13 is located near a middle portion of the antenna 10, and the radio frequency Power Amplifier (PA)12 is electrically connected to the modem 1221 for feeding a signal to the antenna 10 so that the antenna 10 forms a standing wave resonance in a given frequency band. When the voltage detected by the voltage detection sub-module 12 exceeds the preset threshold (the specific process may refer to the content of the voltage detection sub-module 12 described above), a notification message is sent by the voltage detection sub-module 12 (specifically, the first voltage detection chip 1212 or the second voltage detection chip) 1213 to the CPU to inform the CPU that the detected voltage exceeds the preset threshold; then, the CPU may control the modem 1221 to decrease the power of the signal fed from the radio frequency power amplifier 12 to the antenna 10, thereby decreasing the voltage of the antenna 10 until the voltage detected by the voltage detection sub-module 12 does not exceed the preset threshold.
The present disclosure also provides an electronic device, which may include the antenna structure in any of the above embodiments. For the description of the antenna structure in the electronic device, reference may be made to the above embodiments, which are not repeated herein.
Correspondingly, the present disclosure is based on the above antenna structure and electronic device, and further provides an antenna voltage adjusting method. Referring to fig. 8, fig. 8 is a flowchart illustrating a method for adjusting an antenna voltage according to an exemplary embodiment. As shown in fig. 8, the method applied to the electronic device may include the following steps:
in step 802, the voltage near the end of the antenna is monitored.
In this embodiment, the antenna switch is disposed near the end of the antenna, and as can be seen from the above analysis, the voltage at each location on the antenna is inversely related to the distance from the end of the antenna, and when the input voltage to the antenna is large, the antenna switch located near the end of the antenna is at risk of being broken down, burned out, or scattered due to overvoltage. Therefore, by monitoring the voltage near the end of the antenna, when the input voltage to the antenna is large, the above risk of the antenna switch can be found in time, so that corresponding measures are taken to avoid the antenna switch from being damaged. The specific structure of the antenna can refer to the embodiments shown in fig. 2 to 7, and is not described herein again.
In step 804, the input voltage of the antenna is controlled according to the monitored voltage to control the voltage of the antenna switch within a safe range.
In this embodiment, similarly, the process of controlling the input voltage in the adjustment scheme of the antenna voltage according to the present disclosure may refer to the corresponding contents of the embodiments shown in fig. 2 to 7, and is not described herein again.
It can be seen from the above embodiments that, according to the present disclosure, the voltage near the end of the antenna is monitored, and the input voltage of the antenna is controlled according to the monitored voltage, so that the voltage of the antenna switch is within a safe range, thereby effectively preventing the antenna switch from being broken down, burned out, scattered and the like due to overvoltage, and ensuring the normal operation of the antenna.
For ease of understanding, the following detailed description is made in conjunction with fig. 9. Referring to fig. 9, fig. 9 is a flowchart illustrating another method for adjusting the antenna voltage according to an exemplary embodiment. As shown in fig. 9, the method applied to the electronic device may include the following steps:
in step 902, the voltage is monitored.
In step 904, it is determined whether the monitored voltage exceeds a predetermined threshold, and if so, step 906 is performed, otherwise, step 902 is performed.
In the present embodiment, as can be seen from the above-mentioned embodiments shown in fig. 4 to 7, the voltage of the detection resistor 1211 can be monitored or the voltage across the antenna switch 11 can be directly monitored. For the specific monitoring process and the process of comparing with the preset threshold, reference may be made to the related contents of the embodiments shown in fig. 4 to 7, which are not described herein again.
In step 906, the input voltage is reduced and the process returns to step 902.
Similarly, the process of reducing the input voltage in the present embodiment can refer to the content corresponding to the voltage regulator sub-module 122, and is not described herein again.
