[0038] The example embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent the same or similar elements. The following example embodiments described in the detailed description are not meant to be an all-inclusive description of all aspects of the disclosure. Rather, they are merely example devices consistent with some aspects of the disclosure as detailed in the appended claims.

[0039] Reference Figure 1 is a schematic diagram of an antenna module, which comprises:

[0040] a plurality of antenna radiators 1;

[0041] a plurality of matching circuits 2, the matching circuits 2 being connected to the antenna radiators 1; the antenna radiators 1 connected to different matching circuits 2 are different;

[0042] wherein each matching circuit 2 is simultaneously tuned when the terminal device is in any of different working modes.

[0043] The antenna module can be applied to a terminal device. The terminal device can include mobile terminal devices and fixed terminal devices, etc., i.e., the execution subject of the method can at least include mobile terminal devices and fixed terminal devices. The mobile terminal devices can include mobile phones, tablets, vehicle-mounted central control devices, wearable devices, smart devices, and aircraft, etc., and the smart devices can further include smart office devices, smart home devices, and robots, etc. The wearable devices can include watches, glasses, bracelets, and earphones, etc.

[0044] The terminal device can include a controller or a processor, which can be used to control the above-mentioned tuning of each matching circuit.

[0045] The antenna radiators 1 can be part of the frame of a terminal device such as a mobile phone and a tablet, and are used to radiate and receive signals. The structure of the antenna radiators 1 can be determined according to the use requirements, such as the length, width, and position, etc., which can also be determined according to the use requirements, and these information of the antenna radiators 1 in different terminals can be different.

[0046] There can be a gap between the antenna radiators 1, and the two adjacent antenna radiators 1 through the gap can be coupled.

[0047] The connection point between the matching circuit 2 and the connected antenna radiator 1 is the feeding point. The feeding point is used to introduce the electrical signal on the radio frequency transceiver module in the electronic device to the antenna radiator 1 through the feed line, so that the antenna radiator 1 can radiate the wireless signal of the corresponding frequency band under the excitation of the electrical signal, and when the antenna radiator 1 receives the wireless signal of the corresponding frequency band, the electrical signal converted from the received wireless signal of the corresponding frequency band is input into the radio frequency transceiver module through the feed line.

[0048] The matching circuit 2 is used to tune the antenna radiator 1, so that the antenna radiator 1 can resonate with signals of different frequency bands and / or frequency points.

[0049] The matching circuit 2 is connected with the antenna radiator 1, and the connection position of the matching circuit 2 and the antenna radiator 1 is not limited and can be determined according to the use requirement. The structure of the matching circuit 2 is not limited and can include a switch and circuit branches. The switch can be electrically connected with different circuit branches, so as to realize different tuning.

[0050] The matching circuit 2 is also connected with the feed source, for example, one end away from the antenna radiator is connected with the feed source.

[0051] For example, referring to Figure 2 , a schematic diagram of a matching circuit, the matching circuit can include:

[0052] A switch assembly 201;

[0053] A plurality of circuit branches 202 connected with the switch assembly 201; different circuit branches 202 are used to resonate the connected antenna radiator 1 with wireless signals of different frequency bands.

[0054] The switch assembly 201 can be a single-pole multi-throw switch, a multi-pole multi-throw switch, a multi-pole single-throw switch, etc.

[0055] The number of the circuit branches 202 is not limited, and the number of the circuit branches 202 in different matching circuits can be different. The circuit structures of different circuit branches 202 can also be different. The circuit branch 202 can include electronic components for tuning, such as impedance components, capacitive components, and / or inductive components, etc. The same circuit branch 202 can separately include impedance components, capacitive components, or inductive components, and can also simultaneously include multiple impedance components, capacitive components, and inductive components.

[0056] Exemplarily, when impedance devices are included in the circuit branches, the number and impedance values of the impedance devices can be different, and the tuning effects can also be different. When capacitive devices are included in the circuit branches, the number and capacitance values of the capacitive devices can be different, and the tuning effects can also be different. When inductive devices are included in the circuit branches, the number and inductance values of the inductive devices can be different, and the tuning effects can also be different.

[0057] Exemplarily, the impedance devices can include resistors, the capacitive devices can include capacitors, and the inductive devices can include inductors.

[0058] Exemplarily, the switch assemblies 201 and / or the plurality of circuit branches 202 included in different matching circuits can be different, and the resulting tuning effects can also be different.

[0059] Exemplarily, one matching circuit can be connected with one antenna radiator.

[0060] The terminal device transmits and receives signals through the antenna, and different antenna radiators 1 in the antenna can radiate and receive, and the matching circuit 2 can tune to control the antenna radiators 1 in the antenna to resonate with signals of a matching frequency band, so as to realize the transmission and reception of signals of the resonant frequency band.

[0061] The working mode of the terminal device can be determined according to the signal transmission and reception conditions of each antenna radiator 1 in the antenna. The signal transmission and reception conditions can include the data amount and / or signal strength of signal transmission and reception, etc.

[0062] Since different antenna radiators 1 can resonate with signals of different frequency bands, and the matching circuit is used to control the signals resonated by the antenna radiators 1. In the case that the signal transmission and reception conditions of each antenna radiator 1 are different, the tuning states of each matching circuit 2 will also be different, and the working mode of the terminal device will also be different.

[0063] Exemplarily, the signal transmission and reception conditions can be queried through a corresponding application or tool in the terminal device, that is, the terminal device has a function of obtaining the signal transmission and reception conditions of each antenna radiator. The signal transmission and reception conditions can be the signal transmission and reception conditions in a target period, and the length of the period can be determined according to business requirements.

[0064] The terminal device can also determine the current signal strength of the terminal device, and thus determine the signal strength state in which the antenna radiator 1 is located. The signal strength state in which the antenna radiator 1 is located can be a state related to the signal strength of the cellular network, such as a state related to the signal strength of the current cell. The terminal device has a function of detecting the current signal strength, and the detection manner is not limited. The current signal strength can be determined according to the manner set by the terminal device when it is manufactured, or by using an application program that can query the signal strength. Of course, the current signal strength can also be determined in other manners.

[0065] The signal strength can include one or more of the following, and is not limited. The signal strength can include Reference Signal Receiving Power (RSRP), Signal to Interference plus Noise Ratio (SINR), Receive Signal Channel Power (RSCP), or other information that can represent the signal strength.

[0066] Each signal strength state corresponds to a respective signal strength range, and different signal strength states correspond to different signal strength ranges. In this way, the signal strength state can be determined according to the signal strength.

[0067] The tuning state of each matching circuit can be determined according to the use requirement. Each matching circuit can be tuned individually. After the different matching circuits are tuned respectively, the antenna radiator connected to each matching circuit can resonate with the signal of the tuned frequency band, and thus transmit and receive the information. The tuning effect of different matching circuits can be different, and the frequency band of the signal that each antenna radiator resonates can be different. The tuning effect of different matching circuits can be the same, and the frequency band of the signal that each antenna radiator resonates can be the same.

[0068] After the tuning of the matching circuit, the frequency band range of the signal that each antenna radiator 1 can resonate can be the same. In this way, each antenna radiator 1 can resonate with the signal of the same frequency band after being tuned by the corresponding matching circuit, so that multiple antenna radiators 1 can transmit and receive the signal of the same frequency band, and the transmission and reception effect of the signal of the frequency band can be improved.

[0069] After the tuning of the matching circuit, the frequency band range of the signal that each antenna radiator 1 can resonate can have an overlapping frequency band, i.e., an overlapping or same frequency band.

[0070] Exemplarily, after the matching circuit tunes the signal resonated by the connected antenna radiator, the frequency band range of the signal resonated by each antenna radiator is the same. For example, the frequency band range of the signal resonated by each antenna radiator can all be the low frequency band, all be the medium frequency band, all be the high frequency band, etc.

[0071] Exemplarily, after the matching circuit tunes the signal resonated by the connected antenna radiator, the frequency band range of the signal resonated by each antenna radiator is different.

[0072] On the one hand, in this way, after the respective matching circuits tune, each antenna radiator 1 resonates with the signal of the same frequency band in the cross frequency band, so that multiple antenna radiators 1 can transmit and receive the signal of the same frequency band, and the transmission and reception effect of the signal of the frequency band is improved.

[0073] On the other hand, when different matching circuits perform different tuning, the frequency bands of the frequencies resonated by different antenna radiators 1 can be different. In addition to the signal of the cross frequency band, the antenna radiator 1 can also resonate with the signal of the frequency band outside the cross frequency band, thereby improving the signal transmission and reception range and improving the signal transmission and reception effect.

[0074] The matching circuits in the antenna module cooperate to perform tuning, which reduces the situation that when a single matching circuit performs tuning, the signal is transmitted and received through the antenna radiator currently resonating with the signal of the resonant frequency band, i.e., reduces the influence of the signal currently unable to resonate on the current antenna radiator caused by signal transmission and reception through a single antenna radiator. By tuning the antenna radiators connected to the respective matching circuits, the terminal device can transmit and receive signals through multiple antenna radiators in the same working mode, and multiple antenna radiators can transmit and receive signals of the same frequency band or signals of each frequency band used in the working mode, thereby improving the tuning effect and improving the signal transmission and reception effect and the user experience.

[0075] In one embodiment, each matching circuit has multiple tuning states, and different circuit branches in the matching circuit are connected to the antenna radiator, so that the tuning effect of the matching circuit is different.

[0076] The terminal device is in a first working mode, and the terminal device transmits and receives wireless signals of a first frequency band. Each matching circuit is in a respective first tuning state, and is used to resonate the antenna radiator connected thereto with the wireless signal of the first frequency band.

[0077] In this case, the first frequency band can be a frequency band used by the terminal device in the first working mode, each matching circuit is in a corresponding first tuning state, and each antenna radiator connected to the matching circuit resonates with signals of the first frequency band. In this way, the effect of receiving and transmitting signals of the first frequency band can be improved, thereby improving the user experience.

[0078] For example, when the different matching circuits are in the respective first tuning states, the circuit branches connected to the antenna radiators can be different, i.e., the electronic components used for tuning in the circuit branches connected to the antenna radiators are different.

[0079] For example, the first frequency band can be a frequency band corresponding to a cellular signal, a frequency band corresponding to a positioning signal, a frequency band corresponding to a Bluetooth signal, a frequency band corresponding to a satellite communication signal, or a frequency band corresponding to a wireless local area network signal, etc.

[0080] In an embodiment, the terminal device uses a function corresponding to the first frequency band to indicate that the terminal device is in the first working mode. That is, the function corresponding to the first frequency band used by the terminal device can be used to determine that the terminal device is in the first working mode, and thus the first frequency band used by the terminal device can be determined. The function corresponding to the first frequency band can also be associated with the working mode of the terminal device. After the function corresponding to the first frequency band is determined, the working mode of the terminal device can be determined according to the function corresponding to the first frequency band.

[0081] The first frequency band can be associated with the function corresponding to the first frequency band. When it is determined that the terminal device is using the function, the frequency band of the signal to be received and transmitted by the terminal device can be determined.

[0082] The function herein can be a function related to resonance of the antenna module, such as a function related to signal reception and transmission of different frequency bands, including but not limited to a voice service function, a data service function, a positioning function, a satellite communication function, a Bluetooth function, and / or a wireless local area network function, etc. Different functions correspond to different frequency bands, or at least not completely the same, and there can be partial overlap.

[0083] For example, the voice service can be a voice call service based on Voice over Long-Term Evolution (VoLTE) of a 4G network, a voice call service based on Voice over New Radio (VoNR) of a 5G network, a voice call (CS Call) service based on a 2G and / or 3G network, etc.

[0084] The data service can be a voice over long-term evolution (VoLTE) based on a 4G network, a voice over new radio (VoNR) based on a 5G network, a data service of a 2G and / or 3G network, or the like.

[0085] For example, the function currently used by the terminal device is a function based on a cellular network, and it can be determined that the frequency band to be resonated by the antenna is the frequency band of the cellular network. The frequency band can also indicate the working mode of the terminal device.

[0086] In one embodiment, the terminal device is in the second working mode, and the terminal device transmits and receives wireless signals of a plurality of different target frequency bands. Each matching circuit is in a respective second tuning state; and the wireless signals of each target frequency band resonate with at least one antenna radiator connected to the matching circuit.

[0087] In this embodiment, when the terminal device is in the second working mode, the frequency bands of the signals resonated by at least two antenna radiators are different, and the terminal device can transmit and receive wireless signals of a plurality of different target frequency bands, and the frequency bands of the signals transmitted and received by at least two different antenna radiators are different. The wireless signals of the same target frequency band resonate with at least one antenna radiator connected to the matching circuit.

[0088] When the number of target frequency bands is less than the number of antenna radiators, there are more than two antenna radiators connected to the matching circuit and the wireless signals of the same target frequency band. This reduces the signal interference caused by a single antenna radiator transmitting and receiving wireless signals of a plurality of different target frequency bands, and also reduces the poor effect caused by a single antenna radiator transmitting and receiving wireless signals of a target frequency band, thereby improving the transmission and reception effect of the wireless signals of the target frequency band, thereby improving the resonance effect and improving the user experience.

[0089] For example, the wireless signals of a plurality of different target frequency bands can include wireless signals of more than two target frequency bands. These include but are not limited to: a first frequency band that can be a frequency band corresponding to a cellular signal, a frequency band corresponding to a positioning signal, a frequency band corresponding to a Bluetooth signal, a frequency band corresponding to a satellite communication signal, or a frequency band corresponding to a wireless local area network signal, etc.

[0090] In one embodiment, the terminal device uses a function corresponding to each target frequency band to indicate that the terminal device is in the second working mode. That is, the target frequency band used by the terminal device can also be determined according to the function corresponding to the target frequency band used by the terminal device, so as to determine the target frequency band used by the terminal device. The function corresponding to the target frequency band can also be associated with the working mode of the terminal device, and after determining the function corresponding to the target frequency band, the working mode of the terminal device can be determined according to the function corresponding to the target frequency band.

[0091] Each target frequency band can be associated with a function corresponding to the target frequency band, and when it is determined that the terminal device is using the function, the frequency band of the signal to be received and transmitted by the terminal device can be determined.

[0092] The function here can be a function related to the resonance of the antenna module, such as a function related to the signal transmission and reception of different frequency bands, including but not limited to a voice service function, a data service function, a positioning function, a satellite communication function, a Bluetooth function, and / or a wireless local area network function, etc. Different functions correspond to different frequency bands, or at least not completely the same, and there can be partial overlap.

[0093] For example, if the function currently used by the terminal device is a function based on a cellular network and a positioning function, it can be determined that the target frequency band to be resonated by the antenna includes the frequency band of the cellular network, i.e., the first target frequency band, and the frequency band corresponding to the positioning signal, i.e., the second target frequency band. The target frequency band can also indicate the working mode of the terminal device. When there are multiple target frequency bands, receiving different frequency bands indicates that the terminal device is currently in a second working mode.

[0094] For example, the terminal device has the ability to determine the currently used function, and can detect and identify the currently used function.

[0095] In one embodiment, the terminal device is in a standby mode, and the tuning state of each matching circuit changes according to a preset period, and each antenna radiator resonates with the wireless signal of the same frequency band in the same time period. In different time periods, at least part of the tuning state of the matching circuit is different, and the frequency band of the wireless signal resonated by each antenna radiator is different.

[0096] This embodiment is for tuning in standby mode, which can include a mode without running background applications and a mode in idle state, etc. In this mode, the amount of wireless signal transmission and reception of the terminal device is less than a preset value.

[0097] In this mode, the frequency band of the signal resonated by each antenna radiator can be adjusted to the same frequency band in the same period or time period. In different periods or time periods, the frequency band of the signal resonated by each antenna radiator is different. In this way, the polling transmission and reception of signals of each frequency band can be realized, thereby maintaining the signal transmission and reception service of the terminal device. Signals of each frequency band can be transmitted and received, reducing the influence of signal transmission and reception of each frequency band, and improving the user experience.

[0098] For example, the period or time period here can be preset, and the unit can be minutes, seconds, or milliseconds, etc. The shorter the period or time period, the better the polling effect, which can reduce the interval of the resonance of the antenna radiator with the signal of the same frequency band, balance the transmission and reception of wireless signals of each frequency band, improve the tuning effect, and further improve the signal transmission and reception effect.

[0099] In one embodiment, the terminal device is in a fourth operating mode corresponding to the target operation.

[0100] Each matching circuit is in a fourth tuning state and remains unchanged, and each antenna radiator resonates with the wireless signals of the second frequency band.

[0101] In this embodiment, the target operation can be a user inputted operation that determines the operating mode of the terminal device, and the target operation can cause the terminal device to accept signals of a specified frequency band.

[0102] In this case, each matching circuit can be adjusted to a fourth tuning state and remains unchanged. In this tuning state, each antenna radiator can resonate with the wireless signals of the second frequency band, i.e., the signals of the frequency band to be transmitted and received by the terminal device in the fourth operating mode. In this way, the effect of transmitting and receiving the wireless signals of the second frequency band can be enhanced, and the user's experience can be improved.

[0103] In one embodiment, each antenna radiator is located on the same side of the terminal device, and at least some of the plurality of antenna radiators have a coupling relationship or are parasitic branches to each other.

[0104] Each antenna radiator is located on the same side of the terminal device, such as the top frame, or the bottom frame, or the side frame.

[0105] In addition, at least some of the plurality of antenna radiators have a coupling relationship or are parasitic branches to each other, for example, some adjacent antenna radiators have a coupling relationship or are parasitic branches to each other, or each adjacent antenna radiator has a coupling relationship or is a parasitic branch to each other.

[0106] Since each antenna radiator is connected with a matching circuit, each matching circuit can tune the signal frequency band resonated by the antenna radiator connected thereto, and at least some of the plurality of antenna radiators have a coupling relationship or are parasitic branches to each other. Therefore, in combination with the positions of the antenna radiators in the terminal device and the relative positional relationship between the antenna radiators, each matching circuit can tune the resonated signals of the connected antenna radiators and the resonated signals of the antenna radiators having a coupling relationship or being parasitic branches to each other with the connected antenna radiators.

[0107] The coupling relationship or parasitic relationship exists between at least some of the plurality of antenna radiators, which are located on the same side of the terminal device. Therefore, the tuning of the resonant signals of the antenna radiators can be realized when the matching circuits are simultaneously tuned, and the frequency bands of the resonant signals of the antenna radiators can be realized through the tuning of the matching circuits, so that the frequency bands of the resonant signals of the antenna radiators can be more accurately determined, and the signal transmission and reception efficiency can be improved. At the same time, the space occupied by the terminal device can be reduced, and the distance between the antenna radiators can be reduced.

[0108] In one embodiment, a gap exists between adjacent antenna radiators. The coupling or parasitic relationship between the adjacent antenna radiators can be realized through the gap. The size of the gap can be determined according to requirements.

[0109] For example, the plurality of antenna radiators are arranged in a straight line, and each antenna radiator is in a strip shape. Alternatively, some of the antenna radiators are in a bent state, and some of the antenna radiators are in a strip shape.

[0110] For example, the lengths of the antenna radiators are the same.

[0111] For example, at least one of the plurality of antenna radiators is grounded, and each of the antenna radiators can be ungrounded.

[0112] In one embodiment, a terminal device is also provided, which includes the antenna module in any of the above embodiments.

[0113] Reference Figure 3 A schematic diagram of a control method of an antenna module is provided, and the method includes the following steps.

The mobile terminal device can include a mobile phone, a tablet computer, a vehicle-mounted central control device, a wearable device, a smart device, and an aircraft, and the smart device can include a smart office device, a smart home device, and a robot.

[0117] The description of this part can refer to the description of the corresponding embodiments of the antenna module part, and the description will not be repeated.

[0118] In one embodiment, each matching circuit has multiple tuning states;

[0119] S200, according to the current working mode, control each matching circuit in the antenna module to tune simultaneously, including:

[0120] When the terminal device is in the first working mode, adjust each matching circuit to a respective first tuning state, so that the antenna radiator connected to each matching circuit resonates with the wireless signal of the first frequency band;

[0121] Wherein, the terminal device transmits and receives the wireless signal of the first frequency band when in the first working mode.

[0122] In one embodiment, S100, determine the current working mode of the terminal device, including:

[0123] When the terminal device uses the function corresponding to the first frequency band, determine that the terminal device is in the first working mode.

[0124] In one embodiment, each matching circuit has multiple tuning states;

[0125] S200, according to the current working mode, control each matching circuit in the antenna module to tune simultaneously, including:

[0126] When the terminal device is in the second working mode, adjust each matching circuit to a respective second tuning state, so that the wireless signal of each target frequency band resonates with the antenna radiator connected to at least one matching circuit;

[0127] Wherein, the terminal device transmits and receives the wireless signal of multiple target frequency bands when in the second working mode.

[0128] In one embodiment, S100, determine the current working mode of the terminal device, including:

[0129] When the terminal device uses the function corresponding to multiple target frequency bands, determine that the terminal device is in the second working mode.

[0130] In one embodiment, the terminal device is in standby mode;

[0131] S200, according to the current working mode, control each matching circuit in the antenna module to tune simultaneously, including:

[0132] Adjust the tuning state of each matching circuit according to a preset period, so that each antenna radiator resonates with the wireless signal of the same frequency band within the same time period;

[0133] The tuning states of the at least partial matching circuits are different in different time periods, and the frequency bands of the wireless signals resonated by the respective antenna radiators are different.

[0134] In one embodiment, the terminal device is in a fourth working mode corresponding to the target operation.

[0135] In one embodiment, S200, according to the current working mode, the respective matching circuits in the antenna module are controlled to be tuned at the same time, including:

[0136] The respective matching circuits are adjusted to the respective fourth tuning states and remain unchanged, so that the respective antenna radiators resonate with the wireless signals of the second frequency band.

[0137] In one embodiment, S100, the current working mode of the terminal device is determined, including:

[0138] The data transceiving amount of the respective antenna radiators in the target period is determined, and the current working mode is determined according to the data transceiving amount.

[0139] The data transceiving amount of the respective antenna radiators in the target period can be compared with a preset threshold value. When the data transceiving amount of one antenna radiator in the target period exceeds the preset threshold value, the current working mode is determined to be the first working mode.

The tuning states of y matching circuits other than the matching circuits connected to the x antenna radiators are adjusted. After adjusting the tuning states of the y matching circuits, the frequency bands of the signals resonated by the antenna radiators connected to the y matching circuits are close to the frequency bands resonated by the top k antenna radiators with the largest proportion. Alternatively, after adjusting the tuning states of the y matching circuits, the frequency bands of the signals resonated by the antenna radiators connected to r matching circuits in the y matching circuits are moved to the frequency bands resonated by the top k antenna radiators with the largest proportion. r is less than y, and k is less than x.

[0143] In this way, the transceiving effect of the wireless signal of the frequency band with more data transceiving in the second working mode can be improved.

[0153] In one embodiment, each matching circuit has multiple tuning states;

[0155] When the terminal device is in a second working mode, adjust each matching circuit to a respective second tuning state, so that the wireless signal of each target frequency band resonates with the antenna radiator connected to at least one matching circuit;

[0156] In the second working mode, the terminal device transceives the wireless signal of multiple target frequency bands.

[0157] In one embodiment, the determining module 10 is configured to:

[0158] When the terminal device uses a function corresponding to multiple target frequency bands, determine that the terminal device is in the second working mode.

[0159] In one embodiment, the terminal device is in a standby mode;

[0160] The control module 20 is configured to:

[0161] adjust the tuning state of each of the matching circuits according to a preset period, so that each of the antenna radiators resonates with wireless signals of a same frequency band in a same time period;

[0162] wherein in different time periods, the tuning state of at least part of the matching circuits is different, and the frequency band of the wireless signals resonated by each of the antenna radiators is different.

[0163] In one embodiment, the terminal device is in a fourth working mode corresponding to a target operation;

[0164] The control module 20 is configured to:

[0165] adjust each of the matching circuits to a respective fourth tuning state and keep unchanged, so that each of the antenna radiators resonates with wireless signals of a second frequency band.

[0166] In one embodiment, the determination module 10 is configured to:

[0167] determine the amount of data transmission and reception of each of the antenna radiators in a target period;

[0168] determine the current working mode according to the amount of data transmission and reception.

[0169] In one embodiment, the matching circuit comprises:

[0170] a switch assembly;

[0171] a plurality of circuit branches connected with the switch assembly, and different circuit branches are configured to resonate the connected antenna radiators with wireless signals of different frequency bands.

[0172] In one embodiment, another embodiment of a control method of an antenna module is also provided.

[0173] Generally, the antenna used by each communication system in a terminal device can only maintain balanced performance. This cannot reasonably optimize the antenna performance according to the current service condition of the terminal device, and cannot make the antenna performance optimal for the scene.

[0174] Taking a mobile phone as an example, the antenna radiators are located on the middle frame of the mobile phone, and the length of each radiator and the position of the gap can have different lengths according to the supported frequency band. If it is a folding type, the left radiator and the right extension branch are symmetrically distributed on both sides of the shaft.

[0175] In the antenna module provided in this embodiment, with reference to Figure 1On the antenna radiator, the connection point between the antenna of each communication system and the matching circuit is the feed point. For example, the antenna feed point of a satellite communication system, the antenna feed point of a cellular communication system, and the antenna feed point of a WIFI communication system. In the vicinity of the antenna feed point, there is a matching circuit 2, and each antenna radiator is connected with its own matching circuit 2. The matching circuit 2 here can include antenna tuning active devices, which can be used for resonance frequency tuning, parasitic resonance frequency tuning, radiation efficiency optimization, etc.

[0176] Figure 1 The folding screen terminal device shown in the middle has a parasitic branch on the right side of the antenna radiator, which is also connected with a corresponding matching circuit, mainly used for parasitic resonance tuning.

[0177] For example, each antenna tuning active device is located on a printed circuit board (PCB), and there is a controller, such as a central processing unit, including a device control module, on the PCB. The device control module adjusts the state of the antenna tuning active device.

[0178] For example, the antenna state switching method:

[0179] In the non-mandatory mode, the antenna active tuning device is dynamically adjusted.

[0180] In the working mode:

[0181] For example, in the first working mode, when working in a single communication system, the control module pre-stores the state and issues it to the antenna tuning device, so that it remains in the optimal antenna state of the communication system; the phone can remain in the best state of the current communication system.

[0182] In the second working mode, when working in multiple communication systems, the control module needs to make multiple judgments to determine the service volume of the current phone service through the communication system to determine the main state S0 and the auxiliary states S1, S2, and S3. The control module issues the main state S0 and the auxiliary states S1, S2, and S3 to adjust the current phone state, so that the phone always remains in the best data state.

[0183] In the third working mode, in the standby mode:

[0184] The control module polls in the self-defined state to maintain the phone connection service. In the large service volume scenario, the working mode is triggered.

[0185] In the fourth working mode, in the mandatory mode, the antenna active tuning device is locked in a fixed state, and the antenna remains in the best performance of the set communication system.

[0186] The scheme of the embodiment can reduce the physical distance between antennas, solve the problem of insufficient space for the layout of the antenna of the mobile phone, improve the peak performance of the antenna of each communication system, and reduce the compatibility problem of the antenna of each communication system.
