On this basis, the electronic device can, in subsequent steps, determine the candidate antenna with the highest antenna performance from the N candidate antennas according to the received signal strength corresponding to each candidate antenna, as the transceiver antenna of the electronic device.

204. Determine a candidate antenna with the highest antenna performance from the plurality of candidate antennas according to the signal strength corresponding to each candidate antenna, and configure the candidate antenna with the highest antenna performance as a transceiver antenna of the electronic device.

In the embodiment of the present application, after determining the signal strengths corresponding to the above-mentioned candidate antennas, the electronic device can perform comparative analysis based on the respective signal strength values, comprehensively judge the antenna performance of each candidate antenna, and then determine the antenna performance from the antenna performance. The highest candidate antenna. Exemplarily, if the signal strength value corresponding to a certain antenna to be selected is larger, it can indicate that the detection signal transmitted by the antenna to be selected has relatively large gain and relatively little attenuation during transmission, so that the antenna to be selected is more powerful. It is suitable as the current transceiver antenna for electronic equipment.

In some embodiments, the electronic device may directly compare the signal intensities corresponding to each candidate antenna in a horizontal direction to determine the corresponding candidate antenna with the highest signal strength, and configure it as a transceiver antenna of the electronic device.

Such an antenna detection method can avoid relying on an uncertain external network when detecting antenna performance, resulting in inaccurate or even undetectable detection results. At the same time, the advantages of mutual detection between multiple antennas can also be used to improve the accuracy of the detection results, so that the electronic device can accurately configure the current transceiver antenna with the highest antenna performance, thereby helping to improve the communication performance of the electronic device.

Please refer to FIG. 4 . FIG. 4 is a schematic flowchart of another antenna detection method disclosed in an embodiment of the present application. The method can be applied to the above-mentioned electronic device, and the electronic device may include multiple antennas to be selected. As shown in Figure 4, the antenna detection method may include the following steps:

402. In the case that the target candidate antenna is in a signal transmitting state, set multiple detection antennas corresponding to the target candidate antenna to a signal receiving state, wherein the target candidate antenna is any of the above-mentioned multiple candidate antennas. An antenna to be selected.

In this embodiment of the present application, the electronic device may sequentially use each candidate antenna as the target candidate antenna, and perform detection on the antenna performance of the target candidate antenna. At this time, the electronic device may use all other candidate antennas except the target candidate antenna as the detection antenna corresponding to the target candidate antenna. In order to realize the above detection, after determining the target candidate antenna, the electronic device may set each corresponding detection antenna to the signal receiving state, so as to receive the detection signal transmitted by the target candidate antenna.

It can be understood that when the electronic device sets the detection antenna corresponding to the target candidate antenna to the signal receiving state, the electronic device can also correspondingly set the target candidate antenna to the signal transmission state for transmitting detection signals to the external space. Exemplarily, the electronic device may, in response to the antenna detection instruction, set the target candidate antenna to a signal transmission state, so as to trigger the target candidate antenna to transmit according to the maximum transmission power (that is, the maximum transmission power supported by the target candidate antenna) detection signal; optionally, the electronic device may also configure the target candidate antenna, so that the target candidate antenna transmits the detection signal according to the specified standard test power.

In some embodiments, the electronic device may use a dedicated radio frequency transceiver module to control the transceiver state of each of the above-mentioned candidate antennas. Exemplarily, the radio frequency transceiver module may be provided with different ports for signal transmission and signal reception, and the electronic device may select the antenna to be selected through a single pole double throw (Single Pole Double Throw, SPDT) switch or a selection circuit with similar functions. configuration. When the antenna to be selected is connected to the signal transmitting port on the RF transceiver module, the antenna to be selected can be set to a signal transmitting state; when the antenna to be selected is connected to the signal receiving port on the RF transceiver module, the antenna to be selected is The antenna can be set to the signal reception state.

In other embodiments, the electronic device can also implement the above-mentioned control logic through an application-specific integrated circuit such as an FPGA (Field Programmable Gate Array, Field Programmable Gate Array), so that the electronic device can respond to the antenna detection command to quickly select the currently selected The configuration of the target candidate antenna and the corresponding detection antenna is beneficial to improve the efficiency and flexibility of the electronic device for antenna detection.

404. Detect the received signal strength corresponding to the target candidate antenna by using the detection antennas corresponding to each target candidate antenna in a signal receiving state, respectively.

In the embodiment of the present application, after the electronic device sets the detection antenna corresponding to the target candidate antenna to the signal receiving state, the detection antenna can be used to receive wireless signals in the external space that meet its receiving frequency range. Exemplarily, for the detection signal transmitted by the target candidate antenna, each detection antenna in the signal receiving state can receive the corresponding reception signal of the detection signal respectively, and then can determine the reception signal corresponding to the above-mentioned target candidate antenna according to the received signal. strength.

In some embodiments, the electronic device sequentially uses each candidate antenna as the target candidate antenna, and obtains the received signal corresponding to each target candidate antenna by detecting the respective detection antennas corresponding to each target candidate antenna. After the strength, the above received signal strengths can be uniformly sorted and recorded in the signal strength collection table. Exemplarily, the format of the signal strength collection table may be as shown in Table 1 below ("\" indicates that no data is recorded here).

Table 1:

Among them, A1 to A4 respectively represent each candidate antenna included in the electronic device (taking a total of 4 candidate antennas as an example), for the case where each candidate antenna is used as the target candidate antenna, the other 3 candidate antennas can be set Select the antenna to be in the signal receiving state, so as to obtain the corresponding received signal strength, which is applied in the subsequent steps to realize the evaluation of the antenna performance of each target candidate antenna.

406. Compare the received signal strength corresponding to each candidate antenna with the corresponding calibration data, and determine the candidate antenna with the smallest signal strength drop according to the comparison result, as the candidate antenna with the highest antenna performance, wherein the calibration data Including the maximum measured signal strength corresponding to each candidate antenna.

In the embodiment of the present application, in the case where each candidate antenna is used as the target candidate antenna, each detection antenna corresponding to the target candidate antenna may be correspondingly provided with certain calibration data. The above calibration data can be used to represent the maximum measured signal strength corresponding to each candidate antenna, that is, for the target candidate antenna, the calibration data can represent the maximum measured signal strength that can be detected by each detection antenna corresponding to the target candidate antenna. Measure signal strength. Exemplarily, when the candidate antenna A1 is used as the target candidate antenna, the corresponding detection antennas A2, A3, and A4 are in a state as unobstructed and free from interference as possible, and the detected signals correspond to the detection signals transmitted by A1. The received signal strength of the received signal (ie, the maximum measured signal strength) can be used as the calibration data corresponding to the target candidate antenna A1.

On this basis, in the actual detection process, the received signals detected by each of the detection antennas A2, A3, and A4 corresponding to the detection signal transmitted by A1 may have different degrees of attenuation, so the actually detected received signal strength should be Less than or equal to the above calibration data. Therefore, the electronic device can compare the received signal strength corresponding to each candidate antenna with the corresponding calibration data, and determine the candidate antenna with the smallest signal strength drop based on the difference between the two. In some embodiments, if the maximum transmit power of each candidate antenna is equal or similar, the candidate antenna with the smallest signal strength drop is the candidate antenna with the highest antenna performance among the above candidate antennas.

408. If the currently configured transceiver antenna of the electronic device is not the candidate antenna with the highest antenna performance, switch the currently configured transceiver antenna to the candidate antenna with the highest antenna performance.

In the embodiments of the present application, since the environment in which the electronic device is located may change extremely rapidly (for example, the user moves or places the electronic device by holding it), the transceiver antenna currently configured on the electronic device may not be a candidate antenna with the highest antenna performance. At this time, the electronic device may switch the transceiver antenna, that is, switch the currently configured transceiver antenna to the candidate antenna with the highest antenna performance determined in the above-mentioned antenna detection process. In some embodiments, the electronic device can implement the above-mentioned switching through a dedicated radio frequency transceiver module, and the candidate antenna with the highest antenna performance is set as the transceiver antenna, while other candidate antennas can be left unprocessed, or part of the transceiver can be shielded or disabled function to avoid unnecessary interference to the transceiver antenna and improve the communication performance of the electronic device as much as possible.

It can be seen that, by implementing the antenna detection method described in the above embodiment, an electronic device with multiple antennas can use each candidate antenna as each other's detection antennas, and then can accurately detect the candidate antenna with the highest antenna performance, which can avoid When detecting antenna performance, it relies on an uncertain external network, resulting in inaccurate or even undetectable detection results. At the same time, it can also take advantage of the mutual detection between multiple antennas to improve the accuracy of detection results, so that electronic equipment can be accurately configured. The current transceiver antenna with the highest antenna performance is beneficial to improve the communication performance of electronic equipment. In addition, using pre-measured calibration data to evaluate the antenna performance of the antenna to be selected can effectively reflect the subtle state changes of the antenna, thereby further improving the accuracy and reliability of the antenna detection results.
