Description

Technical Field

[0001] This application relates to the field of intelligent control, and more particularly to a control method and electronic device. Background Technology

[0002] In current terminal products, antennas essentially surround the entire frame or casing. Some high-end products have more than 20 antennas within a limited space, covering frequencies from tens of MHz to tens of GHz. Due to various design considerations, the spacing between antennas is also very limited, often resulting in insufficient isolation. Meanwhile, the 4x4 MIMO (Multiple-Input Multiple-Output) technology of the 5G era brings new features such as higher reception rates, meaning that at least four antennas will be operating on the same frequency simultaneously. These antennas will also be affected by their neighboring antennas. If the isolation is insufficient, the signal will be scattered across neighboring antennas, leading to poor reception, affecting communication reception capabilities, and reducing data transmission efficiency.

Detailed Implementation

[0017] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] In order to reduce interference from other antennas to the signals emitted by the active antenna in an electronic device with multiple antennas, improve the isolation between antennas, enhance the communication reception capability of the active antenna, and improve data transmission efficiency, an embodiment of this application provides a control method, such as... Figure 1 As shown, the method includes: Step 101: In response to switching to the first antenna to transmit the first frequency band signal, determine the second antenna that meets the first target condition.

[0019] In response to switching to the first antenna to transmit the first frequency band signal, it refers to the working mode in an electronic device equipped with multiple antennas, where the first antenna switches from a standby state or other frequency band operating state to a signal transmission and reception operating state, and transmits and receives the first frequency band signal.

[0020] The first antenna and the second antenna are different antennas within the same electronic device. They can be the same or different types of antennas, such as 2 2 MIMO (Multiple-Input Multiple-Output), 4 4MIMO (4-input 4-output multiple-input multiple-output antenna), 8 8MIMO (Eight-input, Eight-output Multiple-input Multiple-output).

[0021] The second antenna is the only antenna in the electronic device besides the first antenna that meets the first target condition. An antenna that meets the first target condition is defined as one whose optimal resonant frequency differs from the frequency of the first band signal transmitted by the first antenna by less than the target difference. Meeting the first target condition means that the optimal resonant frequency of this antenna is relatively close to the frequency of the first band signal currently transmitted by the first antenna. In this case, the second antenna will have a strong absorption, coupling, and interference effect on the first band signal of the first antenna. The isolation between the two antennas cannot meet the communication requirements, resulting in significant signal interference. Therefore, tuning control is required, and this antenna is designated as the second antenna.

[0022] It is understandable that the target difference is used to measure the isolation between the first antenna and the second antenna. If the difference is less than the target difference, it means that the isolation between the two is insufficient, which will lead to mutual interference.

[0023] In one example, the target difference is used to characterize the minimum acceptable frequency spacing threshold in the first antenna operating frequency band. The target difference can be determined based on the bandwidth of the first frequency band signal, the system's target requirement for antenna isolation, or a threshold for the coupling strength between antennas. For example, the target difference can be set to a preset proportional threshold related to the bandwidth of the first frequency band signal, and / or set to a preset frequency spacing threshold, so that the absorption and coupling of the first antenna operating frequency band signal by the resonant frequency of the second antenna outside this threshold is significantly reduced. For example, the target difference can be set to a frequency band difference of 100MHz between the two.

[0024] For example, such as Figure 2 As shown, antenna 1 is switched from standby mode to signal transmission and reception mode, transmitting and receiving signals in the first frequency band, and is thus designated as the first antenna. Among antennas 2, 3, and 4, only the optimal resonant frequency of antenna 2 is less than the target difference between the frequency of the first frequency band signal and the optimal resonant frequency of antenna 2. Therefore, antenna 2 is designated as the second antenna.

[0025] In one example, the second resonant frequency can be the frequency corresponding to the minimum reflection coefficient obtained by frequency sweep measurement during the factory calibration of the second antenna, and stored in the memory unit of the electronic device.

[0026] In another example, the second resonant frequency can be estimated by the control module during operation based on parameters such as the reflection coefficient, VSWR, received signal strength indication, or coupling power of the second antenna.

[0027] Step 102: Adjust the matching tuning component parameters of the second antenna to make the second antenna deviate from the second resonant frequency; wherein, the first target condition indicates that the frequency difference between the first frequency band signal and the second resonant frequency is less than the target difference; the second resonant frequency is the optimal resonant frequency for the second antenna to use for communication; the frequency difference between the adjusted resonant frequency of the second antenna and the first frequency band signal is greater than the target difference.

[0028] Adjusting the matching tuning component parameters of the second antenna can be achieved by sending a control signal to the corresponding tuning component of the second antenna via a control module in the electronic device. This adjusts the matching tuning component parameters of the tuning component, thereby changing the resonant frequency of the second antenna. This causes the second antenna to deviate from its original optimal resonant frequency for communication, i.e., the second resonant frequency.

[0029] The resonant frequency of the second antenna after adjustment needs to have a frequency difference greater than the target difference with the first frequency band signal. A frequency difference greater than the target difference indicates that, by adjusting the matching tuning component parameters of the second antenna, the resonant frequency of the second antenna has moved away from the frequency of the first frequency band signal currently transmitted by the first antenna.

[0030] The above-described solution effectively reduces interference from other antennas to the signal transmitted by the working antenna in electronic devices with multiple antennas, significantly improves the isolation between antennas, and makes the communication reception capability of the working antenna more stable and reliable, while also improving data transmission efficiency. When the first antenna switches to the corresponding frequency band, the second antenna, which is prone to interference, can be accurately identified. By adjusting the matching and tuning components of the second antenna, the second antenna is made to deviate from its original optimal resonant frequency and move away from the frequency of the first frequency band signal transmitted by the first antenna. This reduces signal absorption and coupling between antennas, prevents signals from being dispersed to neighboring antennas and affecting communication performance, and allows multiple antennas to maintain good communication performance even in a limited space.

[0031] In one example of this application, a control method is also provided, wherein in response to switching to the first antenna to transmit a first frequency band signal, a second antenna that satisfies a first target condition is determined, comprising: In response to switching to the first antenna as the main antenna to transmit the first frequency band signal, a second antenna that meets the first target condition is determined among the secondary antennas.

[0032] The main antenna is the antenna selected to undertake the primary signal transmission and reception task in the current operating state, used for transmitting and receiving signals in the first frequency band. The secondary antenna may include "other antennas that are not currently undertaking the primary transmission task of the main antenna (which may include cooperative reception / standby states, etc.)". The secondary antenna is in standby state or undertaking other non-primary signal transmission and reception tasks when the main antenna is working.

[0033] In one example, the control module may first determine a set of candidate antennas from multiple secondary antennas based on the spatial proximity of the antenna arrangement. For example, it may determine secondary antennas whose distance from the first antenna radiator is less than a target distance value, and / or secondary antennas arranged on the side adjacent to the side where the first antenna is located. Subsequently, from this set of candidate antennas, a second antenna is further determined based on a first target condition (i.e., the frequency difference is less than the target difference value).

[0034] In the above scheme, when the first antenna switches to act as the main antenna to undertake the main signal transmission and reception tasks, a second antenna that can interfere with the first antenna is identified from the secondary antenna, and the matching and tuning components of the second antenna are then adjusted. This effectively reduces the impact of the secondary antenna on the main antenna signal, improves the isolation between the main and secondary antennas, makes the main antenna's signal transmission and reception more stable, improves communication reception, and enhances data transmission efficiency. Simultaneously, it allows multiple antennas to maintain stable operation within a limited space.

[0035] In one example of this application, a control method is also provided, wherein if the frequency difference between the adjusted resonant frequency of the second antenna and the first frequency band signal is not greater than a target difference, the method further includes: Adjust the matching tuning component parameters of the second antenna so that the second antenna exhibits impedance mismatch with the signal in the operating frequency band of the first antenna.

[0036] Adjust the matching tuning component parameters of the second antenna, such as capacitance and / or inductance, to disrupt the resonance condition of the second antenna on the first frequency band signal, so that the second antenna enters a non-resonant state on that frequency band, thereby exhibiting an impedance mismatch state on that frequency band.

[0037] In one example, the matching tuning components may include an array of switched capacitors and / or an array of switched inductors, and the control module selects different levels by outputting a control word to change the equivalent impedance and resonant frequency of the second antenna.

[0038] In another example, the matching tuning component could be... A type-T matching network, wherein at least one element is an adjustable element to achieve a shift of the resonant frequency.

[0039] For example, the capacitance and / or inductance can be changed by one level to estimate the frequency difference between the two antennas until the frequency difference between the two antennas is greater than the target difference or reaches the upper limit. If the upper limit is reached but the frequency difference is still not greater than the target difference, the matching tuning component parameters of the second antenna are adjusted to make the second antenna exhibit impedance mismatch in that frequency band.

[0040] It should be noted that the upper limit here can be the upper limit of the number of gears / the upper limit of the adjustable range / the upper limit of the physical range of capacitors and inductors, etc.

[0041] In one example, the second antenna is considered to be in mismatch when the VSWR (Voltage Standing Wave Ratio) is greater than a preset threshold or the reflected power is greater than a threshold.

[0042] In the above scheme, due to limitations in actual multi-antenna equipment such as operating frequency band planning, antenna layout space, or communication standard requirements, the resonant frequency of the second antenna cannot be adjusted to a point where the frequency difference between it and the first antenna's first frequency band signal is greater than the target difference. Alternatively, by adjusting the matching tuning component parameters of the second antenna, the second antenna can exhibit impedance mismatch in the main operating frequency band of the first antenna. This means the second antenna cannot normally receive and conduct signals in that band, thus creating a significant high reflection characteristic on the operating frequency band signal transmitted by the first antenna. This improves the isolation between the two antennas, reduces signal interference, and ensures normal signal transmission and reception and communication performance of the first antenna.

[0043] In one example of this application, a control method is also provided, the method further comprising: If the first antenna is the first target antenna, then the second antenna that satisfies the first target condition is the second target antenna.

[0044] If the first antenna is the third target antenna, then the second antenna that satisfies the first target condition is the fourth target antenna.

[0045] In this document, terms such as "first target antenna" and "third target antenna" are used to indicate different antenna identifiers that can be configured as the main antenna. Terms such as "second target antenna" and "fourth target antenna" are used to indicate at least one secondary antenna identifier that meets the first target condition and requires tuning avoidance control when the corresponding main antenna is in operation. It should be understood that "second target antenna" and "fourth target antenna" can be the same or different, depending on the current operating frequency band of the main antenna and the antenna mapping data.

[0046] When the first antenna changes, the corresponding second antenna will also change.

[0047] For example, such as Figure 2 As shown, the antenna mapping data may include the following entries: When the main antenna is identified as Antenna 1 (i.e., the first target antenna) and it transmits a signal in the first frequency band, the corresponding sub-antenna to be tuned is identified as Antenna 2 (i.e., the second target antenna). When the main antenna is identified as Antenna 3 (i.e., the third target antenna) and it transmits a signal in the corresponding frequency band, the corresponding sub-antenna to be tuned is identified as Antenna 4 (i.e., the fourth target antenna).

[0048] In one example, during the calibration phase, different antennas can be switched sequentially to become the main antenna, and the absorption or coupling strength of each sub-antenna to the main antenna signal can be tested in its operating frequency band. When the frequency difference between a sub-ant and the main antenna operating frequency band is less than the target difference or the isolation is lower than a preset threshold, the sub-ant is recorded as the sub-ant to be tuned under the corresponding main antenna, thereby forming the antenna mapping data.

[0049] In the above scheme, when the first antenna changes, the corresponding second antenna can also be updated synchronously, identifying the second antenna that can interfere with the first antenna in real time. This makes the interference suppression between antennas more closely resemble the actual working conditions, ensuring that different antennas can achieve stable isolation when used as operating antennas, and improving the reliability of the entire antenna system.

[0050] In one example of this application, a control method is also provided, the method further comprising: If the first frequency band signal is the first target frequency band signal, the second antenna that satisfies the first target condition is the fifth target antenna.

[0051] If the first frequency band signal is the second target frequency band signal, the second antenna that satisfies the first target condition is the sixth target antenna.

[0052] In this paper, "first target frequency band signal" and "second target frequency band signal" are used to refer to different operating frequency band signals that the first antenna can transmit, which may correspond to different frequency band identifiers or different frequency band sets. It should be understood that different target frequency band signals may correspond to different bandwidth configurations, carrier frequencies, or communication standard configurations, thereby causing changes in the secondary antenna objects that need to be tuned and avoided.

[0053] In one example, when the first antenna is in operation to transmit signals in the first target frequency band, one of the secondary antennas can be selected as the second antenna. When the first antenna switches to operation to transmit signals in the second target frequency band, at least one secondary antenna can be selected as the second antenna, and the at least one secondary antenna may include two or more antennas.

[0054] When the first frequency band signal of the first antenna changes, the corresponding second antenna will also change.

[0055] For example, antenna mapping data may also include entries distinguished by frequency band: when the first antenna transmits a signal in the first target frequency band, the corresponding sub-antenna to be tuned is identified as antenna 2 (i.e., the fifth target antenna). When the first antenna transmits a signal in the second target frequency band, the corresponding sub-antenna to be tuned is identified as antenna 3 and / or antenna 4 (i.e., members in the sixth target antenna set).

[0056] In the above scheme, when the first frequency band signal transmitted by the first antenna changes, the corresponding second antenna can also be updated synchronously, identifying in real time the second antenna that can interfere with the first frequency band signal of the first antenna. This makes the interference suppression between antennas more closely resemble the actual working state, ensuring that different antennas can achieve stable isolation effects when used as working antennas, and improving the reliability of the entire antenna system.

[0057] This application also provides a control method in one example, such as Figure 3 As shown, the method further includes: Step 201: In response to switching to the third antenna as the main antenna to transmit the third frequency band signal, determine the fourth antenna among the secondary antennas that satisfies the second target condition.

[0058] In this paper, the second objective condition is used to characterize the situation where the frequency difference between the third band signal and the optimal resonant frequency of the fourth antenna is less than the target difference. When the second objective condition is met, the fourth antenna exerts strong absorption, coupling, and interference on the third band signal of the third antenna. Therefore, it is necessary to perform matched tuning control on the fourth antenna to improve isolation.

[0059] In response to switching to the third antenna as the main antenna to transmit third-band signals, it refers to the working mode in an electronic device equipped with multiple antennas, where the third antenna switches from standby mode or other frequency band operating mode to signal transmission and reception mode, and transmits and receives third-band signals.

[0060] In one example, the control module can, based on antenna mapping data, directly determine at least one sub-antenna to be tuned as the fourth antenna when the third antenna is transmitting a third frequency band signal as the main antenna.

[0061] In another example, the control module can calculate the frequency difference between the optimal resonant frequency of each sub-antenna and the third band signal, and identify the sub-antenna with a frequency difference less than the target difference as the fourth antenna.

[0062] The first antenna, second antenna, third antenna, and fourth antenna are different antennas within the same electronic device. They can be the same type of antenna or different types of antennas, such as 2 2 MIMO (Multiple-Input Multiple-Output), 4 4MIMO (4-input 4-output multiple-input multiple-output antenna), 8 8 MIMO (Eight-input, Eight-output Multiple-input Multiple-output).

[0063] The fourth antenna is the only antenna in the electronic device, besides the first and third antennas, that meets the second target condition. An antenna meeting the second target condition is one whose optimal resonant frequency differs from the frequency difference of the third band signal transmitted by the third antenna by less than the target difference. Meeting the first target condition means that the optimal resonant frequency of this antenna is relatively close to the frequency of the third band signal currently transmitted by the third antenna. In this case, the antenna will have a strong absorption, coupling, and interference effect on the third band signal of the third antenna. The isolation between the two antennas cannot meet the communication requirements, resulting in significant signal interference. Tuning control is required, therefore this antenna is designated as the fourth antenna.

[0064] It should be noted that multiple main antennas can exist in the same electronic device, that is, the first antenna and the third antenna can simultaneously serve as main antennas, transmitting signals in the frequency bands corresponding to their respective tasks.

[0065] For example, such as Figure 2 As shown, antenna 1 is determined to switch from standby mode to signal transceiver mode, transmitting and receiving signals in the first frequency band, and is therefore designated as the first antenna. Among antennas 2, 3, and 4, only antenna 2's optimal resonant frequency has a frequency difference less than the target value between it and the first frequency band signal. Therefore, antenna 2 is designated as the second antenna. Antenna 3 is determined to switch from standby mode to signal transceiver mode, transmitting and receiving signals in the third frequency band, and is therefore designated as the third antenna. Among antennas 2 and 4, only antenna 4's optimal resonant frequency has a frequency difference less than the target value between it and the third frequency band signal. Therefore, antenna 4 is designated as the fourth antenna.

[0066] Step 202: Adjust the matching tuning component parameters of the fourth antenna so that the fourth antenna deviates from the fourth resonant frequency; wherein, the second target condition indicates that the frequency difference between the third frequency band signal and the fourth resonant frequency is less than the target difference; the fourth resonant frequency is the optimal resonant frequency for the fourth antenna to be used for communication; the frequency difference between the adjusted resonant frequency of the fourth antenna and the third frequency band signal is greater than the target difference.

[0067] Adjusting the matching tuning component parameters of the fourth antenna can be achieved by sending a control signal to the corresponding tuning component of the fourth antenna via a control module in the electronic device. This adjusts the matching tuning component parameters of the fourth antenna, thereby changing its resonant frequency. This causes the fourth antenna to deviate from its original optimal resonant frequency for communication, i.e., the fourth resonant frequency.

[0068] The resonant frequency of the adjusted fourth antenna needs to have a frequency difference greater than the target difference with the third band signal. A frequency difference greater than the target difference indicates that by adjusting the matching tuning component parameters of the fourth antenna, the resonant frequency of the fourth antenna has moved away from the frequency of the third band signal currently transmitted by the third antenna.

[0069] In the above scheme, when multiple main antennas exist in the electronic device, the secondary antennas that need to be adjusted can be determined for each main antenna. That is, the second and fourth antennas are adjusted accordingly, so that each secondary antenna is far away from the operating frequency band of its corresponding main antenna. This effectively reduces the signal interference of different secondary antennas to the corresponding main antenna, improves the isolation between each main antenna and its corresponding secondary antenna, and ensures that multiple main antennas do not affect each other when working at the same time, maintains stable communication reception capability, and improves the overall data transmission efficiency of the electronic device.

[0070] In one example of this application, a control method is also provided, the method further comprising: Obtain mapping data, which includes the mapping relationship between frequency band signals and matching tuning component parameters.

[0071] The mapping data is pre-set data used to store the mapping relationship between signals of each frequency band and parameters of the matching and tuning components.

[0072] The target matching tuning component parameters are determined based on the first frequency band signal and / or the third frequency band signal, as well as the mapping data.

[0073] When the first antenna transmits the first frequency band signal as the main antenna and / or the third antenna transmits the third frequency band signal as the main antenna, the corresponding matching tuning component parameters can be quickly matched from the mapping data based on the currently operating frequency band signal, and used as the target parameters for adjusting the second antenna and / or the fourth antenna. This allows for quick and accurate adjustment of the matching tuning component parameters of the second antenna or the fourth antenna.

[0074] This application also provides an electronic device, Figure 4 A schematic block diagram of an example electronic device 400 that can be used to implement embodiments of the present disclosure is shown. The electronic device is intended to represent various forms of digital computers, such as laptop computers, desktop computers, workstations, personal digital assistants, servers, blade servers, mainframe computers, and other suitable computers. The electronic device may also represent various forms of mobile devices, such as personal digital processors, cellular phones, smartphones, wearable devices, and other similar computing devices. The components shown herein, their connections and relationships, and their functions are merely illustrative and are not intended to limit the implementation of the present disclosure described and / or claimed herein.

[0075] like Figure 4 As shown, the electronic device 400 includes: First antenna 401; Second antenna 402; The second tuning component 403 is connected to the second antenna 402 and is used to adjust the matching tuning component parameters of the second antenna 402; The radio frequency module 404 is connected to the first antenna 401 and the second antenna 402, and is used to drive the first antenna 401 to transmit a first frequency band signal.

[0076] When the radio frequency module 404 drives the first antenna 401 as the main antenna to transmit the first frequency band signal, it sends the frequency band of the first frequency band signal of the first antenna to the control module 405.

[0077] The control module 405 is connected to the second tuning component 403 and the radio frequency module 404, respectively.

[0078] The control module 405 is used for at least: In response to switching to the first antenna 401 as the main antenna to transmit the first frequency band signal, the second antenna 402 is determined among the secondary antennas.

[0079] When the control module 405 receives the frequency band of the first frequency band signal from the first antenna 401 sent by the radio frequency module 404, it determines that the first antenna 401 should be switched as the main antenna to transmit the first frequency band signal. The second antenna 402 is then identified among the secondary antennas of the electronic device 400.

[0080] Adjust the matching tuning component parameters of the second tuning component 403 so that the second antenna 402 deviates from the second resonant frequency.

[0081] The matching tuning component parameters of the second tuning component 403 are adjusted so that the second antenna 402 deviates from the second resonant frequency, and the frequency difference between the resonant frequency of the adjusted second antenna and the frequency of the first frequency band signal is greater than the target difference.

[0082] For example, the electronic device 400 may also include a first tuning component 406.

[0083] Wherein, the frequency difference between the first frequency band signal and the second resonant frequency is less than the target difference; the second resonant frequency is the optimal resonant frequency for the second antenna 402 to be used for communication; the frequency difference between the adjusted resonant frequency of the second antenna 402 and the first frequency band signal is greater than the target difference.

[0084] Wherein, the distance between the radiator of the first antenna 401 and the radiator of the second antenna 402 is less than the target distance value.

[0085] The target distance value is the pre-set minimum physical distance between antennas. This target distance value is used for initial screening of antennas that pose a risk of signal interference due to their proximity to the radiator of the first antenna 401. When the actual physical distance between any two antennas is less than the target distance value, it indicates that the two antennas are spatially close, making signal coupling and interference between them highly likely, thus meeting the location conditions for being listed as candidate antennas.

[0086] For example, the target distance value is set to 3mm-8mm.

[0087] In one example, antennas whose distance to the radiator of the first antenna 401 is less than the target distance can be first identified as a candidate antenna set. Then, antennas in the candidate antenna set whose resonant frequency differs from the frequency difference of the first frequency band signal by less than the target difference are identified as the second antenna 402. For example, such as... Figure 2 As shown, antenna 2 is determined to switch from standby mode to signal transmission and reception mode, transmitting and receiving signals in the first frequency band, and is thus designated as the first antenna 401. At this time, antennas 1 and 3 in the electronic device have a distance between their radiators and the radiator of antenna 2 that is less than the target distance value, while the distances between the radiators of antenna 4 and the radiators of antenna 1 are all greater than or equal to the target distance value. Therefore, antennas 1 and 3 are designated as the candidate antenna set. Furthermore, among the candidate antennas, only antenna 3 has a resonant frequency whose frequency difference from the first frequency band signal is greater than the target difference value. Therefore, antenna 3 is designated as the second antenna 402.

[0088] The first antenna 401 is disposed on the first side of the electronic device, and the second antenna 402 is disposed on the second side of the electronic device. The first side and the second side are adjacent sides of the electronic device.

[0089] The first and second sides are edges on the frame, casing, or internal structure of an electronic device. Adjacent edges refer to two edges that meet at one end. For example, ... Figure 2 As shown, if the side containing antenna 2 is the first side, then the sides containing antenna 1 and antenna 4 can both be the second side.

[0090] In one example, antennas positioned on the adjacent sides of the first antenna 401 can be identified as a candidate antenna set. Then, antennas in the candidate antenna set whose resonant frequency differs from the first frequency band signal by a frequency less than a target difference are identified as the second antenna 402. For example, such as... Figure 2As shown, antenna 1 switches from standby mode to signal transmission and reception mode, transmitting and receiving signals in the first frequency band, and is thus designated as the first antenna 401. At this time, on the second side adjacent to the first side where antenna 1 is located, there are antennas 2 and 3, which are then designated as the candidate antenna set. Further, it is determined that among the candidate antennas, only antenna 3 has a resonant frequency whose frequency difference from the first frequency band signal is greater than the target difference. Therefore, antenna 3 is designated as the second antenna 402.

[0091] In another example, antennas whose distance to the radiator of the first antenna 401 is less than the target distance, and which are located on the side adjacent to the first antenna 401, can be identified as a candidate antenna set. Then, antennas in the candidate antenna set whose resonant frequency differs from the frequency of the first frequency band signal by less than the target difference are identified as the second antenna 402. For example, such as... Figure 2 As shown, antenna 1 is determined to switch from standby mode to signal transmission and reception mode, transmitting and receiving signals in the first frequency band, and is thus designated as the first antenna 401. At this time, antennas 2, 3, and 4 are located at a distance less than the target distance between their radiators and the radiator of antenna 1. However, only antennas 2 and 3 are positioned on the adjacent side of the first antenna 401. Therefore, antennas 2 and 3 are selected as the candidate antenna set. Furthermore, among the candidate antennas, only antenna 3 has a resonant frequency whose frequency difference from the first frequency band signal is greater than the target difference. Therefore, antenna 3 is designated as the second antenna 402.

[0092] Among them, such as Figure 5 As shown, the electronic device 400 also includes: Third antenna 501.

[0093] The fourth antenna is 502.

[0094] The fourth tuning component 503 is connected to the fourth antenna 502 and is used to adjust the matching tuning component parameters of the fourth antenna 502.

[0095] The radio frequency module 404 is also connected to the third antenna 501 and the fourth antenna 502, and is also used to drive the third antenna 501 to transmit a third frequency band signal.

[0096] When the radio frequency module 404 drives the third antenna 501 as the main antenna to transmit the third frequency band signal, it sends the frequency band of the third frequency band signal of the third antenna 501 to the control module 405.

[0097] The control module 405 is also connected to the fourth tuning component 503 and the radio frequency module 404, respectively.

[0098] The control module 405 is also used for: In response to switching to the third antenna 501 as the main antenna to transmit the third frequency band signal, the fourth antenna 502 is determined among the secondary antennas.

[0099] When the control module 405 receives the frequency band of the third frequency band signal of the third antenna 501 sent by the radio frequency module 404, it determines that it is currently switching to the third antenna 501 as the main antenna to transmit the first frequency band signal. The fourth antenna 502 is then selected from the secondary antennas of the electronic device 400.

[0100] For example, the electronic device 400 may also include a third tuning component 504.

[0101] The matching tuning component parameters of the fourth tuning component 503 are adjusted so that the fourth antenna 502 deviates from the fourth resonant frequency.

[0102] The matching tuning component parameters of the fourth tuning component 503 are adjusted so that the fourth antenna 502 deviates from the fourth resonant frequency, and the frequency difference between the resonant frequency of the adjusted fourth antenna 502 and the frequency of the first frequency band signal is greater than the target difference.

[0103] Wherein, the frequency difference between the third frequency band signal and the fourth resonant frequency is less than the target difference; the fourth resonant frequency is the optimal resonant frequency for the fourth antenna 502 to be used for communication; the frequency difference between the adjusted resonant frequency of the fourth antenna 502 and the third frequency band signal is greater than the target difference.

[0105] The calculation module 601 is further configured to determine a second antenna among the secondary antennas that meets the first target condition in response to switching the first antenna to be used as the main antenna to transmit the first frequency band signal.

[0106] The control module 602 is further configured to adjust the matching and tuning component parameters of the second antenna so that the second antenna exhibits impedance mismatch with the signal in the operating frequency band of the first antenna.
