In order to solve the above problems, embodiments of the present disclosure provide an antenna control method, a terminal and a storage medium, aiming to effectively solve the problem of radiation spurious without affecting the performance of the antenna.

Some embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments may be combined with each other without conflict.

Please refer to FIG. 1 , which is a schematic flowchart of an antenna control method provided by an embodiment of the present disclosure. The antenna control method can be applied to mobile terminal devices such as smartphones, and can also be applied to other devices other than mobile terminals that include antenna control systems.

As shown in Figure 1, the antenna control method includes steps S101 to S103.

S101. Determine the current working scenario of the antenna.

Among them, the types of antennas include but are not limited to TRX (Transceiver, transceiver) antenna, LTE (Long Term Evolution, Long Term Evolution) antenna, NR (New Radio, New Radio) antenna, etc.

For example, the working scenarios of the antenna include a radiation spurious suppression working scenario, a non-radiation spurious suppressing working scenario, etc. For example, the radiation spurious suppression work scenario can also be subdivided into multiple different scenarios according to specific needs, that is, the radiation spurious suppression work scenario includes multiple types.

In order to solve the problem of radiation spurious, for example, an adjustment module with spatial filtering characteristics is provided above the antenna. For example, the adjustment module is a film with frequency-selective characteristics, and a layer of film with frequency-selective characteristics is attached to the housing around the antenna.

Exemplarily, the adjustment module includes but is not limited to an FSS (Frequency Selective Surface) unit array. FSS is generally divided into bandpass type and bandrejection type. The bandpass type and bandresistance type FSS can be adjusted according to the requirements. Overlay Thus, an FSS unit array with multi-frequency filtering characteristics is obtained. Furthermore, the FSS unit array is provided with multiple switches. Among them, switches include but are not limited to digital switches.

For example, multiple digital switches are connected in series between the traces or gaps of the FSS unit array as required, and the resonant frequency of the FSS unit array is changed by making the digital switches work in a short-circuit or open-circuit state, thereby realizing an FSS unit with an adjustable frequency range. array.

Exemplarily, the antenna includes at least one, and each antenna corresponds to a group of adjustment modules. For example, each antenna corresponds to a set of FSS element arrays.

In some embodiments, when the antennas include multiple antennas, the multiple antennas may be of the same antenna type or may be of different antenna types. For example, assume that the antenna includes two antennas, one of which is an LTE antenna and the other is an NR antenna.

During the operation of the mobile terminal, the current working scenario of the antenna of the mobile terminal is determined. For example, the current working scenario of the antenna is determined to be a radiation spurious suppression working scenario, or the current working scenario of the antenna is determined to be a non-radiated spurious suppressing working scenario.

In some embodiments, as shown in Figure 2, step S101 may include sub-step S1011 and sub-step S1012.

S1011. Obtain the working scene data of the antenna.

For example, the antenna control system includes a data processing module, a control module, and an adjustment module such as an FSS unit array. For example, as shown in Figure 3, the antenna control system includes a data processing module M1, a control module M2 and an FSS unit array M3. The control module M2 is connected to the data processing module M1 and the FSS unit array M3 respectively.

The working scene data of the antenna of the mobile terminal is detected through the data processing module M2, and the detected working scene data is transmitted to the control module M2.

S1012. Determine the current working scenario of the antenna according to the working scenario data.

After the control module M2 obtains the working scene data transmitted from the data processing module M1, the control module M2 determines the current working scene of the antenna based on the working scene data.

If there are multiple antennas, the working scenario data corresponding to each antenna is obtained, and the current working scenario of each antenna is determined based on the working scenario data corresponding to each antenna.

S102. Determine the target filtering range corresponding to the current working scenario of the antenna according to the corresponding relationship between the preset working scenario and the filtering range.

Among them, the preset corresponding relationship between the working scene and the filtering range includes but is not limited to the benchmarking data table of the working scene and the filtering range.

In some embodiments, determining the target filtering range corresponding to the current working scenario of the antenna includes: if the current working scenario of the antenna is a non-suppressed radiation spurious working scenario, then determining the target filtering range to support The frequency range of reception and transmission of the whole frequency band; if the current working scenario of the antenna is to suppress radiation spurious working scenario, then determine the target filtering range to be the frequency range including reception and transmission of the relevant frequency band.

By way of example, the radiation spurious suppression work scenarios include a variety of work scenarios. In the correspondence between the work scenarios and the filtering ranges, different radiation spurious suppression work scenarios correspond to different filtering ranges. For example, the working scenarios for suppressing radiation spurious include scenario one and scenario two. The target filtering range corresponding to scenario one is filtering range A, and the target filtering range corresponding to scenario two is filtering range B.

For example, if the antenna is a TRX antenna, and the TRX antenna operates in Band 1, the radiation spuriousness of the second and third harmonics of Band1 exceeds the standard, the current working scenario of the TRX antenna is Scenario 1 of various radiation spurious suppression working scenarios. Determine the corresponding target filtering range to include the receiving and transmitting frequency range of Band1. For another example, if the TRX antenna works in Band41, the sideband radiation spuriousness of Band41 exceeds the standard. The current working scenario of the TRX antenna is Scenario 2 of various radiation spurious suppression working scenarios. The corresponding target filtering range is determined to include the transmission frequency range of Band41.

In some embodiments, before determining the target filtering range corresponding to the current working scenario of the antenna according to the preset corresponding relationship between the working scenario and the filtering range, the method includes: setting a benchmark data table for the working scenario and the filtering range; Determining the target filtering range corresponding to the current working scenario of the antenna according to the corresponding relationship between the preset working scenario and the filtering range includes querying the benchmark data table and determining all the corresponding target filtering ranges corresponding to the current working scenario of the antenna. Describe the target filter range.

For example, the benchmark data table for setting the working scenario and filtering range is shown in Table 1:

Table 1

For example, the benchmark data table of the work scenario and the filtering range is stored. For example, a benchmark data table of working scenarios and filtering ranges is stored in the control module M2.

When the control module M2 receives the working scenario data of the antenna transmitted by the data processing module M1, the control module M2 queries the benchmarking data table of the working scenario and the filtering range, and uses the benchmarking data table of the working scenario and the filtering range as the judgment condition. Determine the target filtering range corresponding to the current working scenario of the antenna.

For example, as shown in Figure 4, the data processing module M1 transmits the working scene data of the antenna to the control module M2. The control module M2 determines the current working scene of the antenna based on the working scene data. If the antenna works in scene one, the control module M2 determines The corresponding target filtering range is filtering range A; if the antenna works in scenario two, the control module M2 determines that the target filtering range is filtering range B; if the antenna works in scenario three, the control module M2 determines that the target filtering range is filtering range C.

In some embodiments, determining the target filtering range corresponding to the current working scenario of the antenna according to the corresponding relationship between the preset working scenario and the filtering range includes: based on the corresponding relationship between the preset working scenario and the filtering range, Determining the target filtering range corresponding to each of the antennas; controlling the adjustment module to work in the target filtering range includes: controlling each group of the adjustment modules to work in the target filtering range of the corresponding antenna .

For example, the antenna of a mobile terminal includes an LTE antenna and an NR antenna. A set of FSS unit arrays are attached above the LTE antenna, and a set of FSS unit arrays are also attached above the NR antenna. The control module M2 determines the corresponding relationship between the preset working scenario and the filtering range. For example, the benchmarking data table of working scenarios and filtering ranges determines the target filtering range corresponding to the LTE antenna and the target filtering range corresponding to the NR antenna respectively. The specific operation process is as described in the above embodiment and will not be described again here.

S103. Control the adjustment module to work in the target filtering range.

For example, the control module M2 controls the FSS unit array to operate in a determined target filtering range, thereby achieving the purpose of adaptively improving radiation spuriousness.

In some embodiments, controlling the adjustment module to operate in the target filtering range includes: controlling each switch to operate in a short circuit state or an open circuit state to change the resonant frequency of the FSS unit array so that the FSS The filtering range of the unit array is the target filtering range.

For example, if the control module M2 determines that the corresponding target filtering range is filtering range A, the control module M2 controls the power supply and off states of multiple digital switches so that the filtering state of the FSS unit array responds to the current working scenario of the antenna and works within the determined The target filtering range can achieve the purpose of adaptively improving radiation spurious.

For example, the corresponding relationship between the filtering range and the working state of each switch is preset. After the target filtering range is determined, the working state of each switch is determined according to the target filtering range, and then each switch is controlled to work in a short circuit state or The open circuit state makes the FSS unit array work in the filtering state corresponding to the target filtering range.

Next, take the 5G mobile terminal as an example to control its antenna. As shown in Figure 5, the specific process of adaptively improving the radiation spuriousness of the 5G mobile terminal is as follows:

301. The data processing module M1 collects the working scene data of the 5G mobile terminal antenna;

302. The control module M2 receives the work scene data transmitted by the data processing module M1;

303. The control module M2 compares the work scene data with the benchmark data table;

304. The control module M2 determines the target filtering range based on the comparison results;

305. The control module M2 controls the FSS unit array to operate in a filtering state corresponding to the target filtering range.

By controlling the filtering state of the FSS unit array to respond to the current working scenario of the antenna, the purpose of adaptively improving the radiation spuriousness of 5G mobile terminals can be achieved, thereby improving the user's communication and data service performance, and increasing the handheld call rate, call drop rate and data business.

In the above embodiment, an adjustment module with spatial filtering characteristics is provided above the antenna. In practical applications, the current working scenario of the antenna is determined and the current working scenario of the antenna is determined based on the correspondence between the preset working scenario and the filtering range. The target filtering range is then controlled, and the adjustment module is controlled to work within the determined target filtering range, responding to the current working scenario of the antenna, thereby achieving the effect of adaptively improving radiation spuriousness without affecting the performance of the antenna.
