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.
It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the embodiments of the present application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The embodiment of the application discloses a wireless antenna adjusting method and device, terminal equipment and a storage medium, which can improve the overall antenna performance of a wireless antenna so as to improve the OTA performance of the terminal equipment.
The following detailed description is made with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic view of an application scenario of a method for adjusting a wireless antenna according to an embodiment of the present application, including a terminal device 10 and a wireless Access Point (AP) 20. The wireless access point 20 is an access point of a wireless network, which can perform transceiving of wireless network signals (e.g., Wi-Fi signals), and the terminal device 10 can access the network by communicating with the wireless access point 20, thereby accessing the internet or other locations in the local area network. The terminal device 10 may include a Wi-Fi antenna 11, and perform Wi-Fi signal transceiving through the Wi-Fi antenna 11 to achieve wireless communication between the terminal device 10 and the wireless access point 20.
Illustratively, the terminal device 10 may include various types of devices or systems having Wi-Fi communication functions, such as a mobile phone, a smart wearable device, an in-vehicle terminal, a tablet Computer, a PC (Personal Computer), and the like. It should be noted that the terminal device 10 shown in fig. 1 is a mobile phone, which is merely an example and does not constitute a limitation on the terminal type of the terminal device 10 in the embodiment of the present application. Illustratively, the wireless access point 20 may comprise various types of wireless access devices or systems, such as a wireless router (including both access and routing functions), a wireless base station, and so forth.
In the embodiment of the present application, the terminal device 10 may start a Wi-Fi communication function, and receive a first Wi-Fi signal sent by the wireless access point 20 through its Wi-Fi antenna 11 (specifically, a receiving antenna RX of the Wi-Fi antenna 11); the terminal device 10 may obtain channel setting information corresponding to the wireless access point 20 according to the received first Wi-Fi signal, where the channel setting information is used to indicate a channel adopted by the wireless access point 20 when sending the first Wi-Fi signal; the terminal device 10 may further acquire channel data corresponding to the channel setting information, and then adjust the resonant frequency of the Wi-Fi antenna 11 based on the channel data so that the resonant frequency of the Wi-Fi antenna 11 matches the channel data. The terminal device 10 adjusts the resonant frequency by controlling the Wi-Fi antenna 11 thereof, so that the resonant frequency of the Wi-Fi antenna 11 matches with a channel selected when the wireless access point 20 transmits the first Wi-Fi signal, and thus the resonant frequency of the Wi-Fi antenna 11 matches with the center frequency and the bandwidth of the first Wi-Fi signal, wherein when matching is achieved, the resonant frequency of the Wi-Fi antenna 11 is within a frequency range defined by the center frequency and the bandwidth of the first Wi-Fi signal, and thus the Wi-Fi antenna 11 can receive the first Wi-Fi signal with optimal antenna performance. On this basis, no matter how the Wi-Fi signal sent by the wireless access point 20 changes (for example, different channels are selected to send the Wi-Fi signal), the terminal device 10 can control the Wi-Fi antenna 11 to adjust the resonant frequency thereof along with the first Wi-Fi signal, and keep the resonant point thereof not deviating from the first Wi-Fi signal, so that the antenna performance of the Wi-Fi antenna 11 on each frequency band can be effectively improved, that is, the overall antenna performance of the wireless antenna is improved, and further, the OTA performance of the terminal device 10 in the OTA test is improved. The OTA performance may be used to characterize the overall radiation performance of the terminal device 10.
Illustratively, to achieve the adjustment of the resonant frequency of the Wi-Fi antenna 11 by the terminal device 10, as shown in fig. 2, the radio frequency link in the terminal device 10 may include the above-mentioned Wi-Fi antenna 11, a tuning circuit 12 and a Wi-Fi transceiver 13, wherein the Wi-Fi antenna 11 may be connected with the tuning circuit 12, and the tuning circuit 12 may also be connected with the Wi-Fi transceiver 13. The Wi-Fi antenna 11 may include a transmission antenna TX and a reception antenna RX (not shown separately). The tuning circuit 12 is a tunable circuit, and the resonant frequency of the tuning circuit 12 can be changed by adjusting the tuning circuit 12, thereby adjusting the resonant frequency of the Wi-Fi antenna 11. Optionally, the Wi-Fi transceiver 13 may have a processor built therein, or may be connected to the processor 14 of the terminal device 10, so as to send a control signal for changing the resonant frequency thereof to the tuning circuit 12 under the control of the processor 14, and receive an electrical signal transmitted by the tuning circuit 12 and corresponding to the Wi-Fi signal received by the Wi-Fi antenna 11, and transmit the electrical signal to the processor 14.
Specifically, when the terminal device 10 receives a first Wi-Fi signal sent by the wireless access point 20 through the Wi-Fi antenna 11 thereof, the terminal device may transmit an electrical signal corresponding to the first Wi-Fi signal through the radio frequency link, and acquire channel data (e.g., channel center frequency, bandwidth, etc.) corresponding to the wireless access point 20 therefrom. When the resonant frequency of the Wi-Fi antenna 11 needs to be adjusted, the processor 14 may control the Wi-Fi transceiver 13 to send a control signal to the tuning circuit 12, where the control signal is used to control the tuning circuit 12 to adjust its resonant frequency (e.g., adjust the impedance of the tuning circuit 12, switch the tuning circuit 12 with different dielectric materials, etc.), so that the resonant frequency of the tuning circuit 12 may be adjusted to match the channel data, and the resonant frequency of the Wi-Fi antenna 11 may be matched to the channel data. By implementing the method, the overall antenna performance of the Wi-Fi antenna 11 can be improved, and further the OTA performance of the terminal device 10 is improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for adjusting a wireless antenna according to an embodiment of the present application. As shown in fig. 3, the wireless antenna adjusting method may include the steps of:
302. and receiving a first Wi-Fi signal sent by the wireless access point through the wireless fidelity Wi-Fi antenna.
In the embodiment of the application, the terminal equipment has a Wi-Fi communication function, namely, the terminal equipment is provided with a Wi-Fi antenna, and Wi-Fi signals can be received and transmitted through the Wi-Fi antenna, so that the first Wi-Fi signals sent by the wireless access point are received. In one embodiment, when a terminal device accesses a wireless access point, a wireless communication connection can be established with the wireless access point, and then a first Wi-Fi signal sent by the wireless access point is received. In another embodiment, the terminal device may not access the wireless access point first, and only receive (or scan) the broadcast signal sent by the wireless access point. When the broadcast signal is received, the terminal device can take the broadcast signal as a first Wi-Fi signal, and acquire channel setting information corresponding to the wireless access point according to the broadcast signal by executing the following steps so as to acquire corresponding channel data, so that the resonant frequency of the Wi-Fi antenna can be adjusted, and after the adjustment is completed, the wireless access point is accessed, so that the performance of a receiving antenna of the Wi-Fi antenna is improved, and the situation that the terminal device is jammed when just accessing a wireless network is avoided.
304. And acquiring channel setting information corresponding to the wireless access point according to the first Wi-Fi signal.
Specifically, when the terminal device receives a first Wi-Fi signal through the Wi-Fi antenna, it actually receives a Wi-Fi data packet sent by the wireless access point. On this basis, the terminal device may unpack and analyze the Wi-Fi packet, and obtain channel setting information corresponding to the wireless access point from the packet message, where the channel setting information is used to indicate a channel (such as a channel identifier, a channel type, and the like) adopted by the wireless access point when sending the first Wi-Fi signal.
Illustratively, the channels may include a range of frequencies and may be distinguished by a channel center frequency and bandwidth for each channel. For example, if the channel center frequency of channel 1 is (a + b)/2 and the bandwidth is b-a, then channel 1 includes a frequency range of [ a, b ]; if the channel center frequency of channel 2 is (c + d)/2 and the bandwidth is d-c, then channel 2 includes a frequency range of [ c, d ]. When the wireless access point sends the first Wi-Fi signal, a certain channel can be selected, the signal to be sent is modulated according to the frequency range included by the channel, and finally the first Wi-Fi signal which is in accordance with the frequency range is output.
In the embodiment of the application, when the wireless access point sends the first Wi-Fi signal, the data to be sent may be packed according to information such as a channel of wireless communication between the wireless access point and the terminal device, so as to obtain and send a Wi-Fi data packet conforming to a Wi-Fi communication format (e.g., a format specified by IEEE 802.11 standard). After receiving the Wi-Fi data packet, the terminal device can obtain corresponding channel setting information by obtaining the data packet message header of the Wi-Fi data packet, so that a channel adopted by the wireless access point when sending the first Wi-Fi signal is accurately obtained. In some embodiments, the Wi-Fi packet may include a management frame and a data frame, where the management frame is used for device detection, device access, and other management functions, and the data frame is mainly used for data transmission between the terminal device and the wireless access point after the terminal device accesses the wireless access point. After receiving the management frame, the terminal device may obtain channel setting information corresponding to the wireless access point by analyzing the management frame.
306. Channel data corresponding to the channel setting information is acquired.
Illustratively, the channel setting information may correspond to channel data in a one-to-one manner, wherein the channel data may include channel data of a channel, such as a channel center frequency, a bandwidth, and the like, used by the wireless access point when transmitting the first Wi-Fi signal. The correspondence between the channel setting information and the channel data may be determined according to an existing Wi-Fi communication standard (e.g., IEEE 802.11 standard, including IEEE 802.11a standard, IEEE 802.11b standard, etc.), or may be determined according to a protocol established by the wireless access point itself. It will be appreciated that the terminal device needs to support the above-mentioned standards or protocols to be able to access the above-mentioned wireless access point.
In one embodiment, the terminal device may look up channel data corresponding to the above channel setting information in a channel data table stored therein, where the channel data table may record a mapping relationship between the channel setting information and the channel data, such as channel data corresponding to each different channel identifier, channel data corresponding to each different channel type, and the like.
In another embodiment, the terminal device may further send the channel setting information to a service device connected to the terminal device, and receive channel data corresponding to the channel setting information returned by the service device.
308. And adjusting the resonant frequency of the Wi-Fi antenna based on the channel data so that the resonant frequency of the Wi-Fi antenna is matched with the channel data.
Illustratively, the terminal device may adjust the resonant frequency of the Wi-Fi antenna by adjusting a tuning circuit of the Wi-Fi antenna, for example, adjusting an impedance of the tuning circuit, switching the tuning circuit with different dielectric materials, and the like, so as to change the resonant frequency of the resonant circuit of the Wi-Fi antenna, and thus change the resonant frequency of the Wi-Fi antenna. By implementing the method, the resonant frequency of the Wi-Fi antenna is adjusted to be matched with the channel data, so that the resonant frequency can be matched with the channel selected when the wireless access point sends the first Wi-Fi signal, and the resonant frequency is matched with the center frequency and the bandwidth of the first Wi-Fi signal as much as possible, so that the Wi-Fi antenna can receive the first Wi-Fi signal with the optimal antenna performance, namely, the antenna gain and the antenna efficiency of the Wi-Fi antenna when receiving the first Wi-Fi signal are improved.
Therefore, by implementing the wireless antenna adjusting method described in the above embodiment, the Wi-Fi antenna is controlled to adjust the resonant frequency, so that the Wi-Fi antenna can receive the Wi-Fi signal sent by the wireless access point with optimal antenna performance. On the basis, no matter how the Wi-Fi signal sent by the wireless access point changes, the terminal equipment can control the Wi-Fi antenna to keep the resonance point of the Wi-Fi antenna not deviating from the Wi-Fi signal, so that the overall antenna performance of the wireless antenna can be effectively improved, and the OTA performance of the terminal equipment in the OTA test is further improved.
Referring to fig. 4, fig. 4 is a schematic flowchart illustrating another method for adjusting a wireless antenna according to an embodiment of the present application. As shown in fig. 4, the wireless antenna adjusting method may include the steps of:
402. and receiving a first Wi-Fi signal sent by the wireless access point through the wireless fidelity Wi-Fi antenna.
Step 402 is similar to step 302 described above, and is not described here again.
404. And acquiring channel setting information corresponding to the wireless access point according to the first Wi-Fi signal, wherein the channel setting information at least comprises a channel identifier corresponding to the first Wi-Fi signal sent by the wireless access point.
In this embodiment of the present application, the channel setting information may include at least a channel identifier corresponding to a channel adopted by the wireless access point when transmitting the first Wi-Fi signal, where the channel identifier may include a channel number (e.g., channel 1, channel 2, etc.), a channel identifier (e.g., channel a, channel b, etc.), and the like. Illustratively, a plurality of channels (i.e., a plurality of frequency ranges) for wireless communication are specified in the IEEE 802.11 standard, including at least 14 channels in the 2.4G band and at least 60 channels in the 5G band, each having its corresponding channel identification, from which the channel employed by the wireless access point when transmitting the first Wi-Fi signal can be accurately determined.
406. A stored channel data table is obtained.
In this embodiment, the terminal device may locally store a channel data table, where the channel data table may record a mapping relationship between the channel identifier and the corresponding channel data, so that the terminal device may directly look up a table according to the acquired channel identifier to obtain the channel data corresponding to the channel identifier.
For example, referring to table 1, table 1 shows a mapping relationship between channel identifications of partial channels of a 2.4G frequency band and corresponding channel data, where the channel data shown in the table may include a channel frequency (i.e., a channel center frequency) and a bandwidth of the channel. It should be noted that, the mapping relationship between the channel id and the corresponding channel data shown in table 1 is not only the entire available channels of the 2.4G band, but also is not unique. It is understood that the terminal device may store the data in table 1 in various manners, including tables, documents, etc., and the terminal device may also store the mapping relationship between the channel identifications of the 5G bands and the corresponding channel data in a similar manner.
Table 1:
| channel identification | Channel frequency (Hz) | Bandwidth (Hz) | Channel identification | Channel frequency (Hz) | Bandwidth (Hz) |
| 1 | 2412 | 20M | 8 | 2447 | 20M |
| 2 | 2417 | 20M | 9 | 2452 | 20M |
| 3 | 2422 | |
10 | 2457 | 20M |
| 4 | 2427 | |
11 | 2462 | 20M |
| 5 | 2432 | |
12 | 2467 | 20M |
| 6 | 2437 | |
13 | 2472 | 20M |
| 7 | 2442 | |
14 | 2422 | 40M |
408. And searching channel data corresponding to the channel identifier in the stored channel data table, wherein the channel data at least comprises a channel center frequency and a bandwidth.
For example, after the terminal device obtains the channel identifier corresponding to the wireless access point according to the first Wi-Fi signal, the terminal device may first obtain a channel data table stored in the terminal device, and then search for the channel data corresponding to the channel identifier on the channel data table, so as to obtain a channel center frequency and a bandwidth adopted by the wireless access point when sending the first Wi-Fi signal, so as to adjust the resonant frequency of the Wi-Fi antenna of the terminal device according to the channel center frequency and the bandwidth in the next step.
As an alternative implementation, since the frequency ranges available for wireless communication may be different in different countries or regions, and therefore the legal channel identifiers may also be different, the terminal device may further limit the table lookup range when looking up the channel data table according to the country code in the channel setting information, thereby reducing the table lookup time and improving the table lookup efficiency.
For example, after acquiring the stored channel data table, the terminal device may first determine a frequency range corresponding to a country code included in the channel setting information according to the country code, and then look up channel data corresponding to the channel identifier and belonging to the frequency range in the channel data table. For example, for the 2.4G band, when the country code included in the channel setting information is "CN", the terminal device may look up the channel data table only in the range of channel identifiers 1 to 13; when the country code included in the channel setting information is "US", the terminal apparatus can look up the channel data table only in the range of channel identifications 1 to 11.
By implementing the method, the search range of the channel data table can be further limited according to the country code included in the channel setting information, so that the speed of searching the table by using the channel identifier is increased, and the efficiency of adjusting the wireless antenna is improved.
410. And adjusting the resonant frequency of the Wi-Fi antenna based on the channel data so that the resonant frequency of the Wi-Fi antenna is matched with the channel data.
Step 410 is similar to step 308, and will not be described herein again.
It can be seen that, by implementing the method for adjusting a wireless antenna described in the above embodiment, channel data of a channel used by a wireless access point when the wireless access point sends a Wi-Fi signal can be quickly and accurately determined in a table lookup manner, and then the Wi-Fi antenna of the terminal device can be controlled according to the channel data to adjust a resonant frequency, so that the Wi-Fi antenna receives the Wi-Fi signal sent by the wireless access point with an optimal antenna performance, thereby improving the overall antenna performance of the wireless antenna and further improving the OTA performance of the terminal device; in addition, the table searching range when the channel data table is searched is limited by acquiring the country code in the channel setting information, so that the table searching time is reduced, the table searching speed is increased, and the adjustment efficiency of the wireless antenna is improved.
Referring to fig. 5, fig. 5 is a flowchart illustrating another method for adjusting a wireless antenna according to an embodiment of the present application. As shown in fig. 5, the wireless antenna adjusting method may include the steps of:
502. and receiving a first Wi-Fi signal sent by the wireless access point through the wireless fidelity Wi-Fi antenna.
Step 502 is similar to step 302 described above, and is not described here again.
504. And acquiring channel setting information corresponding to the wireless access point according to the first Wi-Fi signal, wherein the channel setting information at least comprises a channel identifier corresponding to the first Wi-Fi signal sent by the wireless access point.
506. A stored channel data table is obtained.
508. And searching channel data corresponding to the channel identifier in the stored channel data table, wherein the channel data at least comprises a channel center frequency and a bandwidth.
510. A target tuning circuit matching the channel data is determined from the plurality of tuning circuits of the Wi-Fi antenna.
In the embodiment of the application, the Wi-Fi antenna of the terminal equipment can be connected with a plurality of tuning circuits, and the switch is used for ensuring that the Wi-Fi antenna is only conducted with the determined target tuning circuit at the same time. The number of the plurality of tuning circuits may be equal to the number of channels in the channel data table. In one embodiment, a switch may be provided between the Wi-Fi antenna and each tuning circuit, and when a target tuning circuit is determined, the switch corresponding to the target tuning circuit may be turned on, while the switches of the other tuning circuits are turned off. In another embodiment, the Wi-Fi antenna and the plurality of tuning circuits may be connected in a single-pole multi-throw manner, thereby ensuring that only the determined target tuning circuit can be conductively connected to the Wi-Fi antenna at the same time. Illustratively, as shown in fig. 6, fig. 6 is a modular schematic diagram of a plurality of tuning circuits disclosed in the embodiments of the present application. It should be noted that the multiple tuning circuits shown in fig. 6 are connected to the Wi-Fi antenna through a single-pole multi-throw switch, which is merely an example. In some embodiments, the selection and switching of the plurality of tuning circuits may also be implemented by an FPGA (Field Programmable Gate Array), a PLD (Programmable Logic Devices), or the like.
In particular, the plurality of tuning circuits may correspond to a plurality of sub-circuits of a tunable circuit module of the terminal device, and each tuning circuit may be provided with a different dielectric material having a different dielectric constant, so that each tuning circuit may be tuned with the Wi-Fi antenna at a different frequency, i.e., each tuning circuit corresponds to different tuning data, respectively. When the terminal device finds the channel data corresponding to the channel identifier, a matching target tuning circuit may be determined from the multiple tuning circuits according to the channel data, and tuning data of the target tuning circuit is matched with the found channel data (for example, the tuning data is equal to the channel data, and a difference between the tuning data and the channel data is smaller than a threshold).
Optionally, when there is no tuning circuit matching with the channel data in the plurality of tuning circuits, the tuning circuit having the tuning frequency (i.e., the tuning data) closest to the frequency of the first Wi-Fi signal may be determined as the target tuning circuit, so as to improve the overall antenna performance of the Wi-Fi antenna as much as possible by adjusting the resonant frequency of the Wi-Fi antenna.
512. And controlling the Wi-Fi antenna to be switched to the target tuning circuit so that the resonant frequency of the Wi-Fi antenna is adjusted to be the resonant frequency of the target tuning circuit, and the resonant frequency of the target tuning circuit is matched with the frequency of the first Wi-Fi signal.
Specifically, the terminal device may control the Wi-Fi antenna to switch to the determined target tuning circuit, so that the resonant frequency of the Wi-Fi antenna is adjusted to the resonant frequency of the target tuning circuit, and the resonant frequency is matched with the channel data, that is, the resonant frequency may be matched with the frequency of the first Wi-Fi signal sent by the wireless access point (that is, in a frequency range corresponding to a channel used by the wireless access point to send the first Wi-Fi signal), thereby improving antenna gain and antenna efficiency when the Wi-Fi antenna receives the first Wi-Fi signal, and enabling the Wi-Fi antenna to receive the first Wi-Fi signal with optimal antenna performance. When the wireless access point selects different channels to send the first Wi-Fi signal, the terminal device can control the Wi-Fi antenna to be switched to another tuning circuit, so that the resonant frequency of the Wi-Fi antenna is kept matched with the frequency of the first Wi-Fi signal, and the overall antenna performance of the Wi-Fi antenna is improved.
As an alternative, the channel data may belong to different channel groups, each channel group may include channel data corresponding to at least one adjacent channel, and the number of the tuning circuits may be equal to the number of the channel groups. For example, please refer to table 2, table 2 shows an example of grouping partial channels of the 2.4G band.
Table 2:
for example, after finding the channel data corresponding to the channel identifier, the terminal device may first determine a channel group corresponding to the channel data, and then may determine a target tuning circuit matching the channel group from the plurality of tuning circuits. Because the channel data phase difference of the adjacent channels is small, namely the channel data phase difference corresponding to the channels included in the same channel group is small, by setting the tuning circuit corresponding to the channel group, a plurality of adjacent channels can be considered by the same tuning circuit, the number of the tuning circuits required to be set can be reduced, the circuit design is simplified, and the efficiency of determining the target tuning circuit is improved; and the less tuning circuits can be matched with the channel data in a larger range as much as possible, so that the condition that the tuning circuits matched with the channel data do not exist is reduced, and the reliability of the adjustment of the wireless antenna is ensured.
Therefore, by implementing the wireless antenna adjustment method described in the above embodiment, the resonant frequency of the Wi-Fi antenna can be adjusted by setting the switchable tuning circuits, so that the Wi-Fi antenna receives Wi-Fi signals sent by the wireless access point with optimal antenna performance, the overall antenna performance of the wireless antenna is improved, and the OTA performance of the terminal device is improved; in addition, the target tuning circuit required to be switched is determined by setting the channel group comprising at least one adjacent channel, so that the number of tuning circuits required to be set can be reduced, the efficiency of determining the target tuning circuit is improved, and simultaneously, the target tuning circuit can be matched with channel data in a larger range as much as possible by using fewer tuning circuits, and the reliability of adjusting the wireless antenna is favorably ensured.
Referring to fig. 7, fig. 7 is a flowchart illustrating another method for adjusting a wireless antenna according to an embodiment of the present application. As shown in fig. 7, the wireless antenna adjusting method may include the steps of:
702. and receiving a first Wi-Fi signal sent by the wireless access point through the wireless fidelity Wi-Fi antenna.
Step 702 is similar to step 302 described above, and is not described here again.
704. And acquiring channel setting information corresponding to the wireless access point according to the first Wi-Fi signal, wherein the channel setting information at least comprises a channel identifier corresponding to the first Wi-Fi signal sent by the wireless access point.
706. A stored channel data table is obtained.
708. And searching channel data corresponding to the channel identifier in the stored channel data table, wherein the channel data at least comprises a channel center frequency and a bandwidth.
710. A channel packet corresponding to the channel data is determined.
712. From the plurality of tuning circuits of the Wi-Fi antenna, a target tuning circuit matching the channel minute is determined.
714. And controlling the Wi-Fi antenna to be switched to the target tuning circuit so that the resonant frequency of the Wi-Fi antenna is adjusted to be the resonant frequency of the target tuning circuit, and the resonant frequency of the target tuning circuit is matched with the frequency of the first Wi-Fi signal.
716. And receiving a second Wi-Fi signal sent by the wireless access point.
In the embodiment of the application, after the terminal device controls the Wi-Fi antenna to adjust the resonant frequency, the terminal device can re-receive the second Wi-Fi signal sent by the wireless access point. Illustratively, the terminal device may re-access the wireless access point and establish a wireless communication connection, and then receive a second Wi-Fi signal transmitted by the wireless access point. According to the received second Wi-Fi signal, the terminal device may repeat the above steps 702 to 708 to obtain channel data of a channel used by the wireless access point when transmitting the second Wi-Fi signal. When the reacquired channel data matches the current resonant frequency of the Wi-Fi antenna, it indicates that the adjustment of the Wi-Fi antenna is completed, otherwise, the above steps 710 to 714 may be continued to perform another adjustment.
718. And detecting the antenna performance of the Wi-Fi antenna according to the second Wi-Fi signal.
The antenna performance may include parameters such as antenna gain and antenna efficiency, for example. After the terminal device detects the antenna performance of the Wi-Fi antenna according to the second Wi-Fi signal, whether the antenna performance meets the expected performance requirement or not can be judged in the next step, so that the effectiveness of adjusting the wireless antenna can be ensured.
720. And when the performance of the antenna is lower than a performance threshold value, sending a channel switching request to the wireless access point, wherein the channel switching request is used for requesting the wireless access point to switch a channel for sending a second Wi-Fi signal.
For example, when the terminal device detects that the Wi-Fi antenna performance is lower than the performance threshold according to the received second Wi-Fi signal, it may be considered that, through adjustment of the Wi-Fi antenna, the resonant frequency of the Wi-Fi antenna still cannot be made to match with channel data of a channel used by the wireless access point to transmit the second Wi-Fi signal (for example, the wireless access point switches the channel used to transmit the second Wi-Fi signal, a resonant circuit on the terminal device cannot be adjusted to a required resonant frequency, and the like). On this basis, the wireless access point can be requested to switch the channel for sending the second Wi-Fi signal by sending a channel switching request to the wireless access point, and then the terminal device can re-execute the steps 702 to 714 according to the second Wi-Fi signal after the channel is switched so as to adjust the resonant frequency of the Wi-Fi antenna again, so that the resonant frequency of the Wi-Fi antenna is matched with the channel data of the switched channel, thereby improving the overall antenna performance of the wireless antenna and ensuring the effectiveness and reliability of the adjustment of the wireless antenna.
Therefore, by implementing the wireless antenna adjusting method described in the above embodiment, the Wi-Fi antenna is controlled to adjust the resonant frequency, so that the Wi-Fi antenna can receive the Wi-Fi signal sent by the wireless access point with optimal antenna performance; in addition, when the resonant frequency of the Wi-Fi antenna cannot be adjusted to the required resonant frequency, the effectiveness and the reliability of the adjustment of the wireless antenna can be ensured by requesting the wireless access point to switch the channel adopted by the wireless access point to transmit the Wi-Fi signal and carrying out the adjustment again.
