Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.
As shown in fig. 1, fig. 1 is a flow chart of an antenna tuning method provided by 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, and 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, so that the electronic terminal can be triggered to be in different working modes, namely different functions of the electronic terminal can correspond to different working modes of the electronic terminal, and therefore, the current working mode of the electronic terminal can be determined according to the current executed function of the electronic terminal. According to different types of transmission data when the electronic terminal executes corresponding functions, the functions of the electronic terminal can be divided into two main types, namely a voice call type and a data communication type. For example, the functions of the electronic terminal may include cellular phone call, voLTE (Voice over LTE), weChat Voice, weChat video, browsing web pages, watching video, gaming, high-speed downloading, and so on. The cellular phone call, voLTE, weChat voice, weChat video, etc. may be divided into voice phone call functions, and browsing web pages, watching video, game, high-speed downloading, etc. may be divided into data communication functions.
Because the functions of the electronic terminal are divided into two major categories, the working modes of the electronic terminal can be divided into two major 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, the electronic terminal can be determined to be in a data communication mode.
The electronic terminal may determine the operation mode of the electronic terminal when the corresponding function starts to be executed, or predict the operation mode of the electronic terminal before the corresponding function starts to be executed, so as to determine the operation mode to be currently entered by the electronic terminal according to the predicted operation mode. For example, the electronic terminal may determine that the current operation mode of the electronic terminal is a voice call mode when the user is talking (i.e. the phone is connected) with other users, or may predict that the operation mode to be currently entered by the electronic terminal is a voice call mode when the user dials or rings (waits for connection). The electronic terminal determines the working mode when starting to execute the corresponding function, so that the situation that the user frequently switches the function of the electronic terminal, so that the working mode of the electronic terminal is frequently switched, and the subsequent antenna is frequently tuned is avoided. The electronic terminal predicts the working mode before starting to execute the corresponding function, and can tune the antenna of the electronic terminal in advance, so that the electronic terminal has 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 operation mode in step 102 includes:
when the working mode is a voice call mode, determining that the antenna performance requirement is maximum diversity antenna efficiency; and when the working mode is a data communication mode, determining that the antenna performance requirement is a radiation pattern of the differential main set antenna and the diversity antenna.
It should be noted that, when the operation mode of the electronic terminal is a voice call mode, in order to ensure call quality and long-distance call at the edge of the base station, the antenna is required to have higher antenna efficiency, so the antenna performance requirement may be set to maximize diversity antenna efficiency. When the operation mode of the electronic terminal is a data communication mode, multiple antennas serving as receiving ends in the MIMO antennas are required to be mutually incoherent, so that multiple signals can be distinguished obviously when the multiple signals of the base station are received. The MIMO performance depends on the quality of the MIMO channel model, which is formed by the radiation pattern of the base station antenna, the spatial transmission environment, and the radiation pattern of the electronic terminal antenna, so that for the electronic terminal, the optimization of the MIMO performance can be achieved by optimizing the radiation pattern of the electronic terminal antenna. Therefore, when the working mode of the electronic terminal is a data communication mode, the antenna performance requirement can be set as the radiation patterns 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 assisting in receiving signals, and no signals are transmitted, i.e. the diversity antenna is an auxiliary antenna relative to the main set antenna, the antenna performance requirement is mainly aimed at the performance requirement of the diversity antenna, i.e. only the diversity antenna is tuned subsequently.
103. And tuning the diversity antenna according to the antenna performance requirement.
In the embodiment of the application, the performance of the diversity antenna after tuning can meet the antenna performance requirement. Wherein tuning of the diversity antenna may be achieved by adjusting parameters of tuning devices in the diversity antenna. The tuning device comprises at least one of a tuning switch and an adjustable capacitance, and tuning of the diversity antenna may be achieved by adjusting parameters of the tuning switch and/or the adjustable capacitance 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 of the tuning switch 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 an adjustable capacitor, the adjustable capacitor is connected with the diversity antenna radiator, different capacitance values can be obtained by adjusting parameters of the adjustable capacitor, different antenna matching is realized, and the diversity antenna efficiency and the radiation pattern can be changed.
When the tuning device comprises a tuning switch and an adjustable capacitor, the tuning device can be switched to different channels by adjusting parameters of the tuning switch and parameters of the adjustable capacitor, and different capacitance values are obtained, so that different antenna matching is realized, and the diversity antenna efficiency and the radiation pattern are also changed.
In one embodiment, the tuning the diversity antenna according to the antenna performance requirement in step 103 includes:
and obtaining tuning parameters corresponding to the antenna performance requirements, and adjusting parameters of tuning devices in the diversity antenna to the tuning parameters.
It should be noted that, the electronic terminal may store a table of correspondence between antenna performance requirements and tuning parameters in advance, after determining the antenna performance requirements, the tuning parameters corresponding to the antenna performance requirements may be obtained by looking up a table, so as to directly adjust parameters of tuning devices in the diversity antenna to the tuning parameters, thereby enabling the performance of the diversity antenna to meet the antenna performance requirements, and effectively improving the antenna tuning efficiency.
For example, when the antenna performance requirement is that the diversity antenna efficiency is maximized, the corresponding tuning parameter can be determined to be the first tuning parameter, and the parameter of the tuning device in the diversity antenna is adjusted to be the first tuning parameter, so that the diversity antenna efficiency can be adjusted to be the highest, and the overall antenna efficiency of the electronic terminal is improved, so that the call quality is ensured. When the antenna performance requirement is that the radiation patterns of the main set antenna and the diversity antenna are differentiated, the corresponding tuning parameter can be determined to be 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, the diversity antenna efficiency is properly reduced at the moment, 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 differentiated, and the non-correlation between the main set antenna and the diversity antenna is increased, but the higher the non-correlation is, the better the MIMO performance is.
In another embodiment, the tuning the diversity antenna according to the antenna performance requirement in step 103 includes:
and adjusting parameters of tuning devices in the diversity antenna to enable the performance of the diversity antenna to meet the antenna performance requirement.
After determining the antenna performance requirement, the electronic terminal can directly adjust the parameters of the tuning device in the diversity antenna, detect the performance of the diversity antenna in real time in 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, so as to complete the tuning of the diversity antenna. Tuning in this embodiment can effectively improve tuning accuracy.
Because the main set antenna bears the main communication function, the main set antenna efficiency has a larger influence on the overall antenna efficiency, if the main set antenna efficiency is poor, the overall antenna efficiency is greatly reduced, and the emission performance is also influenced, so that in order to ensure the communication performance of the mobile phone to the greatest extent, the embodiment only tunes the diversity antenna, and the main set antenna performance is kept unchanged.
According to the antenna tuning method provided by the application, the current working mode of the electronic terminal can be determined, the antenna performance requirement is determined according to the working mode, the diversity antenna is tuned according to the antenna performance requirement, and the performance of the electronic terminal in different working modes is improved on the premise that the communication performance of the electronic terminal is not affected.
Referring to fig. 2, another flow chart of an antenna tuning method provided by an embodiment of the present application is shown, where the antenna tuning method is applied to an electronic terminal, and the electronic terminal includes a main set of antennas and diversity antennas, and a specific flow chart of the antenna tuning method may be as follows:
201. detecting a current working mode of the electronic terminal, if the working mode is a voice call 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 current executing function of the electronic terminal, judging the current working mode to be a voice communication mode if the electronic terminal executes the functions of cellular communication and the like, and judging the current working mode to be a data communication mode if the electronic terminal executes the functions of browsing web pages and the like.
202. And acquiring voice call tuning parameters, and adjusting parameters of tuning devices in the diversity antenna to the voice call tuning parameters.
And pre-establishing a corresponding relation between the working mode and the tuning parameters, determining the voice call tuning parameters corresponding to the voice call mode when the current working mode of the electronic terminal is determined 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 diversity antenna efficiency and ensure the call quality.
203. And acquiring a data communication mode, and adjusting parameters of a tuning device in the diversity antenna into the data communication mode.
When the current working mode of the electronic terminal is judged to be a data communication mode, determining data communication tuning parameters corresponding to the data communication mode, and controlling tuning devices in the diversity antenna according to the data communication tuning parameters, so that the radiation patterns of the main set antenna and the diversity antenna are different, and the MIMO performance is improved.
