Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, fig. 1 is a flowchart of an antenna tuning method provided in an embodiment of the present application, where the antenna tuning method is applied to an electronic terminal, and the electronic terminal includes a MIMO antenna, where the MIMO antenna includes a main set antenna and a diversity antenna. The antenna tuning method may comprise steps 101 to 103:
101. and determining the current working mode of the electronic terminal.
In the embodiment of the application, the user performs different operations on the electronic terminal, and the electronic terminal can be triggered to be in different working modes, that is, different functions of the electronic terminal can correspond to different working modes of the electronic terminal, so that the current working mode of the electronic terminal can be determined according to the currently executed function of the electronic terminal. According to different types of data transmission when the electronic terminal executes corresponding functions, the functions of the electronic terminal can be divided into two categories, namely voice call category and data communication category. For example, the functions of the electronic terminal may include cellular telephony, VoLTE (Voice over LTE, IMS based Voice service), WeChat Voice, WeChat video, browsing web pages, viewing videos, gaming, high speed downloads, and so on. The cellular call, VoLTE, WeChat voice, WeChat video and the like can be divided into voice call functions, and the browsing of web pages, video watching, games, high-speed downloading and the like can be divided into data communication functions.
The functions of the electronic terminal are divided into two categories, so that the working modes of the electronic terminal can also be divided into two categories, and when the electronic terminal executes the voice call function, the electronic terminal can be determined to be in the voice call mode; when the electronic terminal executes the data communication function, it can be determined that the electronic terminal is in the data communication mode.
The electronic terminal may determine the working mode of the electronic terminal when starting to execute the corresponding function, or predict the working mode of the electronic terminal before starting to execute the corresponding function, so as to determine the working mode to be entered by the electronic terminal currently according to the predicted working mode. For example, the electronic terminal may determine that the current operating mode of the electronic terminal is a voice call mode when the user makes a call with another user (i.e., the phone is turned on), or may predict that the operating mode to be entered by the electronic terminal is the voice call mode when the user dials a number or rings (waits for the call to be turned on). The electronic terminal determines the working mode when the electronic terminal starts to execute the corresponding function, so that the situation that the working mode of the electronic terminal is frequently switched and further the subsequent antenna is frequently tuned due to frequent switching of the functions of the electronic terminal by a user can be prevented. The working mode of the electronic terminal is predicted before the electronic terminal starts to execute the corresponding function, the antenna of the electronic terminal can be tuned in advance, and the electronic terminal is guaranteed to have good performance in the whole process of executing the corresponding function.
102. And determining the antenna performance requirement according to the working mode.
In the embodiment of the application, when the electronic terminal is in different working modes, the executed functions are different, so that the antenna performance requirements are different. Specifically, the determining the antenna performance requirement according to the operating mode in step 102 includes:
determining that the antenna performance requirement is a maximum diversity antenna efficiency when the operating mode is a voice call mode; and when the working mode is a data communication mode, determining that the antenna performance requirement is the radiation pattern of the differentiated main set antenna and the diversity antenna.
It should be noted that, when the operation mode of the electronic terminal is the voice call mode, in order to ensure the call quality and the long distance call at the edge of the base station, the antenna is required to have higher antenna efficiency, so that the antenna performance can be set to maximize the diversity antenna efficiency. When the operation mode of the electronic terminal is a data communication mode, a plurality of antennas as receiving ends in the MIMO antenna are required to be mutually incoherent so as to be able to clearly distinguish multiple signals when receiving the multiple signals of the base station. The MIMO performance depends on the quality of an MIMO channel model, and the MIMO channel model consists of a radiation pattern of a base station antenna, a space transmission environment and a radiation pattern of an electronic terminal antenna, so that the MIMO performance can be optimized by optimizing the radiation pattern of the electronic terminal antenna for an electronic terminal. Therefore, when the working mode of the electronic terminal is the data communication mode, the antenna performance requirement can be set to be the radiation pattern of the differentiated main set antenna and the diversity antenna.
In addition, since the main set antenna is used for transmitting and receiving signals, the diversity antenna is used for auxiliary receiving signals, and no signals are transmitted, i.e. the diversity antenna is an auxiliary antenna with respect to the main set antenna, the antenna performance requirements are mainly directed to the performance requirements of the diversity antenna, i.e. only the diversity antenna is subsequently tuned.
103. Tuning the diversity antenna according to the antenna performance requirement.
In the embodiment of the application, the performance of the tuned diversity antenna can meet the requirement of the antenna performance. Wherein the tuning of the diversity antenna may be achieved by adjusting parameters of a tuning device in the diversity antenna. The tuning device comprises at least one of a tuning switch and a tunable capacitor, and tuning of the diversity antenna may be achieved by adjusting a parameter of the tuning switch and/or the tunable capacitor in the diversity antenna.
When the tuning device comprises a tuning switch, one end of the tuning switch is connected with the diversity antenna radiator, and the other end is connected with different matching devices. By adjusting the parameters of the tuning switch, the tuning switch is switched to different channels, so that different antenna matching is realized, and the diversity antenna efficiency and the radiation pattern are also changed.
When the tuning device comprises the adjustable capacitor, the adjustable capacitor is connected with the diversity antenna radiator, different capacitance values can be obtained by adjusting the parameters of the adjustable capacitor, different antenna matching is realized, and the diversity antenna efficiency and the radiation pattern can also be changed.
When the tuning device comprises a tuning switch and an adjustable capacitor, the tuning switch can be switched to different channels by adjusting the parameters of the tuning switch and the parameters of the adjustable capacitor, different capacitance values are obtained, different antenna matching is realized, and the diversity antenna efficiency and the radiation pattern can also be changed.
In one embodiment, the tuning the diversity antenna according to the antenna performance requirement in step 103 includes:
and acquiring tuning parameters corresponding to the antenna performance requirements, and adjusting the parameters of tuning devices in the diversity antenna to the tuning parameters.
It should be noted that, a corresponding relation table between the antenna performance requirement and the tuning parameter may be stored in advance in the electronic terminal, after the antenna performance requirement is determined, the tuning parameter corresponding to the antenna performance requirement may be obtained through table lookup, and then the parameter of the tuning device in the diversity antenna is directly adjusted to the tuning parameter, so that the performance of the diversity antenna may meet the antenna performance requirement, and the antenna tuning efficiency is effectively improved.
For example, when the antenna performance requirement is that the diversity antenna efficiency is maximized, the corresponding tuning parameter may be determined as the first tuning parameter, and the parameter of the tuning device in the diversity antenna is adjusted to the first tuning parameter, so that the diversity antenna efficiency is adjusted to be the highest, and the overall antenna efficiency of the electronic terminal is improved, so as to ensure the call quality. When the antenna performance requirement is the radiation pattern of the differentiated main set antenna and the diversity antenna, the corresponding tuning parameter can be determined as the second tuning parameter, the parameter of the tuning device in the diversity antenna is adjusted to be the second tuning parameter, so that the radiation pattern of the diversity antenna is most suitable for MIMO data communication, at the moment, the diversity antenna efficiency is properly reduced, but the radiation pattern of the diversity antenna is changed, so that the radiation patterns of the main set antenna and the diversity antenna are different, the non-correlation between the main set antenna and the diversity antenna is increased, and the higher the non-correlation is, the better the MIMO performance is.
In another embodiment, said tuning said diversity antenna according to said antenna performance requirement in step 103 comprises:
and adjusting parameters of a tuning device in the diversity antenna to enable the performance of the diversity antenna to meet the antenna performance requirement.
It should be noted that, after determining the performance requirement of the antenna, the electronic terminal may directly adjust the parameters of the tuning device in the diversity antenna, detect the performance of the diversity antenna in real time during the adjustment process, and stop adjusting the parameters of the tuning device when detecting that the performance of the diversity antenna meets the antenna performance requirement, thereby completing the tuning of the diversity antenna. The tuning in the embodiment can effectively improve the tuning precision.
Because the main antenna bears the main communication function, the efficiency of the main antenna has a large influence on the overall antenna efficiency, if the efficiency of the main antenna is poor, the overall antenna efficiency is greatly reduced, and the emission performance is also influenced, so that the communication performance of the mobile phone is ensured to the maximum extent, the embodiment only tunes the diversity antenna, and the performance of the main antenna is kept unchanged.
Therefore, the antenna tuning method provided by the application can determine the current working mode of the electronic terminal, determine the antenna performance requirement according to the working mode, tune the diversity antenna according to the antenna performance requirement, and improve the performance of the electronic terminal in different working modes on the premise of ensuring that the communication performance of the electronic terminal is not affected.
Referring to fig. 2, it is another schematic flow chart of the antenna tuning method provided in this embodiment of the present application, where the antenna tuning method is applied to an electronic terminal, and the electronic terminal includes a main set antenna and a diversity antenna, and a specific flow of the antenna tuning method may be as follows:
201. detecting the current working mode of the electronic terminal, if the working mode is a voice communication mode, executing step 202, and if the working mode is a data communication mode, executing step 203.
Judging the current working mode of the electronic terminal according to the function currently executed by the electronic terminal, if the electronic terminal executes the functions of cellular call and the like, judging the current working mode to be a voice call mode, and if the electronic terminal executes the functions of browsing web pages and the like, judging the current working mode to be a data communication mode.
202. And acquiring voice call tuning parameters, and adjusting the parameters of a tuning device in the diversity antenna into the voice call tuning parameters.
The method comprises the steps of establishing a corresponding relation between a working mode and tuning parameters in advance, determining the corresponding voice call tuning parameters of the voice call mode when the current working mode of the electronic terminal is judged to be the voice call mode, and controlling a tuning device in the diversity antenna according to the voice call tuning parameters so as to improve the efficiency of the diversity antenna and ensure the call quality.
203. And acquiring a data communication mode, and adjusting the parameters of the tuning device in the diversity antenna to the data communication mode.
When the current working mode of the electronic terminal is judged to be the data communication mode, the data communication tuning parameter corresponding to the data communication mode is determined, and the tuning device in the diversity antenna is controlled according to the data communication tuning parameter, so that the radiation patterns of the main set antenna and the diversity antenna are different, and the MIMO performance is improved.
According to the method described in the above embodiments, this embodiment will be further described from the perspective of an antenna tuning apparatus, which may be specifically implemented as a stand-alone entity or integrated in an electronic terminal, where the electronic terminal may include a mobile terminal, a wearable device, a PC terminal, a robot, and the like.
