DETAILED DESCRIPTION

[0061] The exemplary embodiments will now be described in detail with reference to the accompanying drawings. The following description, with reference to the drawings, is made in connection with the exemplary embodiments. The same reference numerals are used in different drawings to refer to the same or like elements. The following exemplary embodiments described in the detailed description are not meant to be limiting in any way. Rather, they are provided to illustrate some of the many possible embodiments consistent with the present disclosure.

[0062] In the related art, as shown in Figure 1a The ferrite coil 31 is arranged at the rear camera deco 311 of the back cover of the mobile phone as an NFC antenna, which occupies the thickness of the whole machine. As the number of cameras of the mobile phone increases and the volume becomes larger, the size of the rear camera deco is directly increased, which squeezes the space of the original coil antenna. As shown in Figure 1b The NFC antenna 32 is arranged at the same position as the battery of the mobile phone, which is close to the bottom of the mobile phone in the wireless charging and NFC antenna combination scheme, resulting in poor experience of using NFC card. As the demand for magnetic attraction and accessories increases, the conflict between the NFC antenna 32 and the magnetic attraction and accessories also increases. As shown in Figure 1c The NFC antenna is independently arranged on the metal frame 33 of the mobile phone, which occupies the space of the conventional cellular antenna and short-distance communication antenna in the metal frame on-frame scheme, which affects the performance of other communication antennas.

[0063] Therefore, the antenna module provided by the embodiments of the present disclosure not only has better coverage effect of near field communication signals, but also reduces the occupied space of the antenna module. Figure 2 is a structural schematic diagram of an antenna module according to an example embodiment. As shown in Figure 2 The antenna module 10 can include:

[0064] At least two radiators 11 arranged at intervals;

[0065] Each radiator 11 can transmit and receive a first type of wireless signal, and can also be reused to transmit and receive a second type of wireless signal;

[0066] The second type of wireless signal includes a near field communication signal; the first type of wireless signal includes a wireless signal other than the near field communication signal.

[0067] The antenna module provided by the embodiments of the present disclosure can be arranged in a terminal device. The antenna module can be used to transmit and receive wireless signals. When the antenna module is used to transmit wireless signals, the terminal device can perform wireless signal transmission, such as wireless communication or wireless charging.

[0068] Specifically, the application scenario of the terminal device in which the antenna module provided by the embodiments of the present disclosure can include a wireless communication scenario.

[0069] For example, the wireless communication scenario can be a multi-device scenario. For example, in the scenario of configuring a network for a smart device, the terminal device can interact with other electronic devices through a router or a base station to complete the configuration of the network for the smart device.

[0070] Referring to Figure 3 The wireless communication network environment 200 includes a terminal device 1, other electronic devices 201, a Wireless Fidelity (Wi-Fi) access point 202, a cellular base station 203, and a network 204. Here, when the terminal device 1 and the other electronic devices 201 perform wireless signal transmission and reception using a wireless local area network or a cellular network, the terminal device 1 and the other electronic devices 201 can perform switching between the Wi-Fi and the cellular network through information transmission between the Wi-Fi access point 202 and the cellular base station 203 and the network 204, respectively. It should be noted that, according to the network environment shown in the present disclosure, the Wi-Fi connection is stopped when an instruction for wireless transmission by the cellular base station is received, and the Wi-Fi connection is resumed when an instruction for stopping wireless transmission by the cellular base station is received. Figure 3 It should be noted that, according to the network environment shown in the present disclosure, the Wi-Fi connection is stopped when an instruction for wireless transmission by the cellular base station is received, and the Wi-Fi connection is resumed when an instruction for stopping wireless transmission by the cellular base station is received.

[0071] The antenna module provided by the present disclosure can be applied in the field of wireless signal transmission, and the frequency of the wireless signal transmitted and received by the radiator can be changed, the frequency band of the wireless signal can be improved, and the performance of wireless communication can be optimized.

[0072] In the embodiments of the present disclosure, each of the radiators can transmit and receive the first type of wireless signal and the second type of wireless signal.

[0073] It should be noted that the specific type of each of the radiators can be set according to actual conditions, and the embodiments of the present disclosure do not limit the specific type of each of the radiators. For example, each of the radiators can be formed by a frame of the terminal device; or each of the radiators can be formed by a Flexible Printed Circuit (FPC) process; or each of the radiators can be formed by Laser-Direct-structuring (LDS) manufacturing.

[0074] The first type of wireless signal can include a cellular mobile communication signal, a wireless fidelity communication signal, a Bluetooth communication signal, or a Global Positioning System (GPS) signal; and the second type of wireless signal can include an NFC signal.

[0075] It can be understood that the antenna module can adapt to different scenarios to perform wireless communication using different wireless signals. For example, the first type of wireless signal can be used in a call scenario of the terminal device, and at this time, the first type of wireless signal can be a Low Band (LB), a Middle High Band (MHB), or a New Radio (NR) cellular mobile communication signal; and the second type of wireless signal can be used in a scenario of access control or bus card swiping of the terminal device, and at this time, the second type of wireless signal can be an NFC signal.

[0076] In the embodiments of the present disclosure, each radiator is capable of transmitting and receiving the same first type of wireless signal or a different first type of wireless signal while transmitting and receiving the NFC signal.

[0077] For example, a first part of the radiators is capable of transmitting and receiving the cellular mobile communication signal and the NFC signal, and a second part of the radiators is capable of transmitting and receiving the GPS signal and the NFC signal; or each of the radiators is capable of transmitting and receiving the cellular mobile communication signal and the NFC signal, and the like.

[0078] Here, the center frequency of the first type of wireless signal can be greater than the center frequency of the second type of wireless signal. For example, when the first type of wireless signal is the MHB signal, the center frequency of the first type of wireless signal can be 700 megahertz (MHz); and when the second type of wireless signal is the NFC signal, the center frequency of the second type of wireless signal can be 13.56 MHz.

[0079] In the embodiments of the present disclosure, each of the radiators can be spaced apart in different directions or spaced apart in the same direction. For example, each of the radiators can be spaced apart in the same direction on different planes in a stacked manner, each of the radiators can be spaced apart in the same direction on the same plane, or each of the radiators can be spaced apart in different directions, and the like.

[0080] In addition, the specific shape of each of the radiators can also be set according to the actual application scenario, and the embodiments of the present disclosure do not make any limitation. For example, the shape of the radiator can be in the form of a linear type or an L-shaped type, and the like.

[0081] The antenna module provided by the embodiments of the present disclosure includes: at least two radiators spaced apart; each of the radiators is capable of transmitting and receiving the first type of wireless signal, and can be reused to transmit and receive the second type of wireless signal; the second type of wireless signal includes the near field communication signal; and the first type of wireless signal includes the wireless signal other than the near field communication signal. In this way, the antenna module of the embodiments of the present disclosure does not need to increase an additional radiator to transmit and receive the near field communication signal, but can reuse at least two radiators to transmit and receive the near field communication signal, which not only can realize that the antenna module has a better coverage effect of the NFC signal, improves the performance of the antenna module in transmitting and receiving the NFC signal, but also can reduce the occupied space of the antenna module and improve the space utilization.

[0082] Figure 4 is a structural schematic diagram of an antenna module provided according to an example embodiment Figure 2 As shown in Figure 4 the antenna module provided by the embodiments of the present disclosure, on the basis of the antenna module shown in Figure 2 further increases other devices, for example, the first radio frequency end and the second radio frequency end.

[0083] As shown in Figure 4As shown, the antenna module 10 can further include a first radio frequency end 12 corresponding to the second type of wireless signal and a second radio frequency end 13 corresponding to the first type of wireless signal;

[0084] The first radio frequency end 12 is connected to at least two radiators 11.

[0085] The second radio frequency end 13 is connected to at least one of the radiators 11.

[0086] In the embodiments of the present disclosure, the first radio frequency end can be a port for outputting and inputting signals of a first radio frequency module in the antenna module, and the first radio frequency module can establish a communication connection with each of the radiators through the first radio frequency end to realize the transmission and reception of the second type of wireless signal.

[0087] For example, the first radio frequency end can be an NFC antenna radio frequency end. The NFC antenna radio frequency end outputs a first NFC electrical signal and excites each of the radiators to emit an NFC signal through the first NFC electrical signal; or each of the radiators can convert a received wireless signal into a second NFC electrical signal and then transmit the second NFC electrical signal to the NFC antenna radio frequency end through a feed line, so as to realize the reception of the NFC signal by each of the radiators.

[0088] In the embodiments of the present disclosure, the second radio frequency end can be a port for outputting and inputting signals of a second radio frequency module in the antenna module, and the second radio frequency module can establish a communication connection with at least one of the radiators through the second radio frequency end to realize the transmission and reception of the first type of wireless signal.

[0089] For example, the second radio frequency end can be an NR antenna radio frequency end. The NR antenna radio frequency end outputs a first NR electrical signal and excites at least one of the radiators to emit an NR signal through the first NR electrical signal; or at least one of the radiators can convert a received wireless signal into a second NR electrical signal and then transmit the second NR electrical signal to the NR antenna radio frequency end through a feed line, so as to realize the reception of the NR signal by at least one of the radiators.

[0090] In the embodiments of the present disclosure, the connection of the second radio frequency end to at least one of the radiators can include that a first part of the radiators is connected to the second radio frequency end and a second part of the radiators is not connected to the second radio frequency end; or each of the radiators is connected to the second radio frequency end.

[0091] It can be understood that the connection of each of the radiators to the second radio frequency end can include that each of the radiators is connected to one second radio frequency end, and the radiators connected to different second radio frequency ends transmit and receive different first type of wireless signals. That is, each of the radiators is connected to a different second radio frequency end, so that each of the radiators can transmit and receive different first type of wireless signals.

[0092] For example, as shown in FIG. 1, the antenna module 10 can include a plurality of radiators 11, a first radio frequency module 12 and a second radio frequency module 13. Figure 4As shown, the at least two radiators 11 can include a first radiator 116 and a second radiator 117; at this time, the first radiator 116 is connected to the second radio frequency end 13 capable of transmitting cellular mobile communication signals, and the second radiator 117 is connected to the second radio frequency end 13 capable of transmitting GPS signals.

[0093] Here, the first part of the radiator is connected to the second radio frequency end, and the second part of the radiator is not connected to the second radio frequency end, which can be understood as: the at least two radiators include the first part of the radiator and the second part of the radiator, the first part of the radiator is connected to the second radio frequency end, and the second part of the radiator transmits and receives the first type of wireless signal after being coupled with the first part of the radiator. That is, the second part of the radiator not connected to the second radio frequency end can transmit and receive the first type of wireless signal through coupling.

[0094] Exemplarily, the at least two radiators can include a first radiator, a second radiator and a third radiator, and the first radiator is located between the second radiator and the third radiator. At this time, the first radiator is connected to the second radio frequency end capable of transmitting cellular mobile communication signals, and the second radiator and the third radiator are not connected to the second radio frequency end, but transmit and receive cellular mobile communication signals by being coupled with the first radiator respectively.

[0095] In the embodiments of the present disclosure, the antenna module can connect different first radio frequency ends and second radio frequency ends, so that the radiators can simultaneously transmit and receive the first type of wireless signal and the second type of wireless signal, thereby not only improving the signal transmission and reception performance of the antenna module, but also reducing the occupied space of the antenna module. Moreover, by setting multiple connection modes of the at least two radiators and the second radio frequency end, the flexibility of the antenna module layout can be improved on the basis of realizing that each radiator can transmit and receive the first type of wireless signal.

[0096] In some embodiments, as Figure 4 As shown, each radiator 11 has a ground point 111 and a first upper frame point 112 connected to the first radio frequency end 12;

[0097] When each radiator 11 transmits and receives the second type of wireless signal, a current is formed between the first upper frame point 112 and the ground point 111;

[0098] The current direction of each radiator 11 is clockwise or counterclockwise.

[0099] In the embodiments of the present disclosure, the ground point can be the connection point of each radiator and the ground wire; and the first upper frame point can be the connection point of each radiator and the first radio frequency end.

[0100] It can be understood that the first upper frame point can be a feed point corresponding to the second type of wireless signal received and transmitted by each radiator, and thus the current path in each radiator can be a path between the first upper frame point and the return point. That is, when the positional relationship between the first upper frame point and the return point on each radiator changes, the current direction of each radiator also changes, that is, the current direction of each radiator changes from clockwise to counterclockwise, or the current direction of each radiator changes from counterclockwise to clockwise.

[0101] It should be noted that the specific number of the return points and the first upper frame points can be set according to actual application conditions, as long as the number of the return points and the first upper frame points is the same as the number of the radiators, and the present disclosure does not limit.

[0102] In the present embodiment, the antenna module can ensure that the current direction between the first upper frame point and the return point in each radiator is clockwise or counterclockwise, thereby ensuring that the magnetic flux direction of each radiator when receiving and transmitting the second type of wireless signal is consistent.

[0103] In some embodiments, as shown in FIG. 1, each of the radiators 11 has a first upper frame point 112 and a return point 113. Figure 4 As shown in FIG. 1, each of the radiators 11 has a first upper frame point 112 and a return point 113.

[0104] When the current direction of the first radiator 116 and the current direction of the second radiator 117 are both clockwise P1, the length of the first radiator 116 between the first upper frame point 112 and the gap 114 is greater than the length of the second radiator 117 between the first upper frame point 112 and the gap 114.

[0105] When the current direction of the first radiator 116 and the current direction of the second radiator 117 are both counterclockwise P2, the length of the first radiator 116 between the first upper frame point 112 and the gap 114 is less than the length of the second radiator 117 between the first upper frame point 112 and the gap 114.

[0106] Here, since at least two radiators are spaced apart, each of the radiators has a gap between adjacent radiators. For example, in the case where the antenna module includes two radiators spaced apart, the two radiators have one gap therebetween; in the case where the antenna module includes three radiators spaced apart, the three radiators have two gaps therebetween.

[0107] It can be understood that when the current direction of the first radiator and the current direction of the second radiator are both clockwise, the first upper frame point on the first radiator is far away from the above-mentioned break, and the return point on the first radiator is close to the break; the first upper frame point on the second radiator is close to the break, and the return point on the second radiator is far away from the break.

[0108] like Figure 4 As shown, when the current direction of the first radiator 116 and the current direction of the second radiator 117 are both counterclockwise P2, the first upper frame point 112 on the first radiator 116 is close to the break 114, and the return point 111 on the first radiator 116 is far away from the break 114; the first upper frame point 112 on the second radiator 117 is far away from the break 114, and the return point 111 on the second radiator 117 is close to the break 114.

[0109] For example, when the first radiator and the second radiator are both in the shape of a straight line, and the current directions of the first radiator and the second radiator are both clockwise, the first upper frame point on the first radiator is set away from the break, and the first upper frame point on the second radiator is set close to the break; in this case, the first upper frame points on the first radiator and the second radiator are both located to the left of the return point. When the first radiator and the second radiator are both in the shape of a straight line, and the current directions of the first radiator and the second radiator are both counterclockwise, the first upper frame point on the first radiator is set close to the break, and the first upper frame point on the second radiator is set away from the break; in this case, the first upper frame points on the first radiator and the second radiator are both located to the right of the return point.

[0110] In the embodiment of the present disclosure, the antenna module can increase the effective radiation length of each radiator when sending and receiving the second type of wireless signal by setting the positional relationship between the first upper frame point, the return point and the break in each radiator, thereby improving the effect of each radiator in sending and receiving the second type of wireless signal.

[0111] In some embodiments, as Figure 4 As shown, the radiator 11 connected to the second RF end 13 further has a second upper frame point 113 connected to the second RF end 13;

[0112] The second upper frame point 113 and the first upper frame point 112 of the same radiator 11 are located at the same position; or,

[0113] In the same radiator 11 , the second upper frame point 113 is located between the first upper frame point 112 and the return point 111 .

[0114] In the embodiments of the present disclosure, the second upper frame point can be a connection point of the radiator and the second radio frequency end, that is, the second upper frame point can be a feeding point of the radiator connected to the second radio frequency end for receiving and transmitting the first type of wireless signal.

[0115] It can be understood that when the second upper frame point and the first upper frame point are located at the same position in the same radiator, the first radio frequency end and the second radio frequency end can be connected to the radiator through the same connection point. When the second upper frame point is located between the first upper frame point and the ground point in the same radiator, the connection point of the first radio frequency end and the radiator can be different from the connection point of the second radio frequency end and the radiator.

[0116] In the embodiments of the present disclosure, the antenna module can be configured to share or not share the second upper frame point and the first upper frame point in the same radiator, so that each radiator can receive and transmit the first type of wireless signal and the second type of wireless signal, thereby improving the flexibility of the antenna module layout.

[0117] Figure 5 is a structure diagram of an antenna module provided according to an example embodiment Figure 3 As shown in Figure 5 , the antenna module provided by the embodiments of the present disclosure further increases other devices on the basis of the antenna module shown in Figure 4 , for example, a first matching circuit, a filtering circuit, an isolation component and a second matching circuit.

[0118] As shown in Figure 5 , the antenna module 10 can further include:

[0119] The first matching circuit 14 is connected to the connection line between each radiator 11 and the first radio frequency end 12, and is configured to adjust the frequency of the second type of wireless signal received and transmitted by the radiator 11.

[0120] In the embodiments of the present disclosure, the first matching circuit can be a circuit capable of adjusting the impedance on the connection line between each radiator and the first radio frequency end.

[0121] It can be understood that the first electric signal output by the first radio frequency end can be transmitted to each radiating body through the connecting line between the first radio frequency end and each radiating body, so that each radiating body emits the second type of wireless signal under the excitation of the first electric signal; or the second electric signal obtained by each radiating body converting the second type of wireless signal can be transmitted to the first radio frequency end through the connecting line between the first radio frequency end and each radiating body, so as to realize that each radiating body receives the second type of wireless signal. At this time, in the transmission process of the first electric signal or the second electric signal, the first matching circuit can adjust the impedance on the connecting line between the first radio frequency end and each radiating body, so as to reduce the loss caused by the mismatch between the impedance of each radiating body and the impedance of the first radio frequency end, thereby improving the transmission power of the first electric signal or the second electric signal.

[0122] In the embodiment of the present disclosure, the antenna module can adjust the frequency of the radiating body receiving and transmitting the second type of wireless signal by setting the first matching circuit on the connecting line between each radiating body and the first radio frequency end, thereby improving the effect of the radiating body receiving and transmitting the second type of wireless signal.

[0123] In an embodiment of the present disclosure, as shown in Figure 6 The first matching circuit includes at least one first impedance component 141 and / or at least one second impedance component 142.

[0124] The connecting line between each radiating body 11 and the first radio frequency end 12 is provided with a connection node A.

[0125] The at least one first impedance component 141 is connected to the connecting line between the corresponding radiating body 11 and the connection node A.

[0126] One end of the at least one second impedance component 142 is connected to the connecting line between the connection node A and the first radio frequency end 12, and the other end of the at least one second impedance component 142 is grounded; or the at least one second impedance component 142 is connected to the connecting line between the connection node A and the first radio frequency end 12.

[0127] In the embodiment of the present disclosure, the first impedance component can include an inductive element, or the first impedance component can also include an inductive element and a capacitive element.

[0128] For example, at least one inductive element is connected in series on the connecting line between each radiating body and the connection node; at this time, the number of inductive elements can be greater than or equal to the number of radiating bodies.

[0129] It can be understood that the first impedance component can adjust the frequency of each radiating body receiving and transmitting the second type of wireless signal, and can also be used to isolate the high-frequency signal input to the first radio frequency end.

[0130] Here, the second impedance component can include a capacitive element, or the second impedance component can include a capacitive element and an inductive element.

[0131] For example, the first matching circuit includes at least one second impedance component, and the second impedance component includes a capacitive element. When the at least one capacitive element is one, one end of the capacitive element is connected to a connection line between the connection node and the first radio frequency end, and the other end of the capacitive element is grounded; or when the at least one capacitive element is two, one of the capacitive elements is connected in parallel to the connection line between the connection node and the first radio frequency end, and the other of the capacitive elements is connected in series to the connection line between the connection node and the first radio frequency end, and so on.

[0132] In the embodiments of the present disclosure, the connection node can be a convergence point of each radiator on a connection line between each radiator and the first radio frequency end.

[0133] For example, as shown in Figure 6 When the at least two radiators 11 include a first radiator 116 and a second radiator 117, the first impedance component 141 can include two inductive elements, i.e., an inductive element L1 and an inductive element L2, and the second impedance component 142 can include two capacitive elements, i.e., a capacitive element C1 and a capacitive element C2. At this time, the inductive element L1 is connected in series between the first radiator 116 and the connection node A, the inductive element L2 is connected in series between the second radiator 117 and the connection node A, one end of the capacitive element C1 is connected between the connection node A and the first radio frequency end 12, the other end of the capacitive element C1 is grounded, and the capacitive element C2 is connected in series between the connection node A and the first radio frequency end 12.

[0134] In the embodiments of the present disclosure, the antenna module can improve the flexibility of the antenna module layout on the basis of being capable of adjusting the frequency of each radiator to transceive the second type of wireless signal through different connection modes of the first impedance component and / or the second impedance component in the first matching circuit.

[0135] In some embodiments, as shown in Figure 5 The antenna module 10 can further include:

[0136] The filtering circuit 15 is connected to a connection line between the first matching circuit 14 and the first radio frequency end 12, and is configured to filter spurious signals output by the first radio frequency end 12 or input to the first radio frequency end 12.

[0137] In the embodiments of the present disclosure, the filtering circuit can be a circuit capable of filtering spurious signals output by the first radio frequency end or input to the first radio frequency end; and the filtering circuit can include at least one inductive element and at least one capacitive element.

[0138] Here, the filtering principle of the filtering circuit is the combination of the inductive element and the capacitive element based on their respective basic characteristics. Because the capacitive reactance of the capacitive element decreases with the increase of the signal frequency, and the inductive reactance of the inductive element increases with the increase of the signal frequency, if the capacitive element and the inductive element are connected in series, in parallel or mixed, the impedance of their combination also changes with the signal frequency, so that different filtering circuits can present very small or very large impedance to a certain frequency signal, so as to allow the signal to pass through smoothly or hinder it from passing through, thereby playing a role in selecting a certain frequency signal and filtering a certain frequency signal.

[0139] For example, as shown in FIG. 1, the filtering circuit 15 can include an inductive element L3 connected in series and a capacitive element C3 connected in parallel. Figure 6 In the case where the at least two radiators 11 include a first radiator 116 and a second radiator 117, the filtering circuit 15 can include an inductive element L3 connected in series and a capacitive element C3 connected in parallel. The inductive element L3 is connected in series between the capacitive element C2 in the first matching circuit and the first radio frequency end 12. One end of the capacitive element C3 is connected to the connecting line between the capacitive element C2 and the inductive element L3 in the first matching circuit, and the other end of the capacitive element C3 is grounded.

[0140] In the embodiments of the present disclosure, the antenna module can filter the spurious signal output by the first radio frequency end or input to the first radio frequency end by arranging the filtering circuit on the connecting line between the first matching circuit and the first radio frequency end, thereby improving the effect of the radiator in transmitting and receiving the second type of wireless signal.

[0141] In some embodiments, as shown in FIG. 1, the antenna module 10 can further include: Figure 5

[0142] The isolation component 16 is connected to the connecting line between the radiator 11 and the second radio frequency end 13, and is configured to isolate the first type of wireless signal.

[0143] In the embodiments of the present disclosure, the isolation component can be composed of at least one capacitive element. For example, when the isolation component is composed of one capacitive element, the capacitive element can be connected in series to the connecting line between the radiator and the second radio frequency end. When the isolation component is composed of multiple capacitive elements, the multiple capacitive elements are connected in parallel to each other, and each capacitive element is connected to the connecting line between the radiator and the second radio frequency end.

[0144] It can be understood that when the radiator transmits the second type of wireless signal, the second radio frequency end outputs the signal corresponding to the first type of wireless signal; when the radiator receives the second type of wireless signal, the second radio frequency end inputs the signal corresponding to the first type of wireless signal.

[0145] ​Here, the capacitor element or the plurality of capacitor elements arranged on the connecting line between the radiator and the second radio frequency end can isolate the signal corresponding to the first type of wireless signal output by the second radio frequency end or input to the second radio frequency end when the radiator transceives the second type of wireless signal, so as to reduce the influence of the radiator transceiving the second type of wireless signal on the antenna performance of transceiving the first type of wireless signal, and further realize the compatibility between the first type of wireless signal and the second type of wireless signal transceived by each radiator.

[0146] In the embodiments of the present disclosure, the antenna module can isolate the first type of wireless signal by arranging the isolation component on the connecting line between the radiator and the second radio frequency end, so as to avoid the interference of the radiator transceiving the second type of wireless signal on the transceiving of the first type of wireless signal, and improve the signal transceiving performance of the antenna module.

[0147] In some embodiments, as shown in FIG. 1, the antenna module 10 can further include: Figure 5

[0148] The second matching circuit 17 is connected to the isolation component 16 at different positions of the connecting line between the radiator 11 and the second radio frequency end 13, and is configured to adjust the frequency of the first type of wireless signal transceived by the radiator.

[0149] In the embodiments of the present disclosure, the second matching circuit can be a circuit capable of adjusting the impedance on the connecting line between the radiator and the second radio frequency end.

[0150] Here, the second matching circuit can also include at least one inductive element and / or at least one capacitor element. The second matching circuit can adjust the impedance on the connecting line between the second radio frequency end and the radiator through the at least one inductive element and / or the at least one capacitor element, so as to adjust the frequency of the first type of wireless signal transceived by the radiator, and further improve the effect of the first type of wireless signal transceived by the radiator.

[0151] It should be noted that the isolation component can be connected between the radiator and the second matching circuit, or the isolation component can also be connected between the second matching circuit and the second radio frequency end, and the embodiments of the present disclosure do not make any limitation.

[0152] ​It can be understood that the third electric signal output by the second radio frequency end can be transmitted to the radiator through the connecting line between the second radio frequency end and the radiator, so that the radiator emits the first type of wireless signal under the excitation of the third electric signal; or the fourth electric signal obtained by converting the first type of wireless signal by the radiator connected to the second radio frequency end can be transmitted to the second radio frequency end through the connecting line between the second radio frequency end and the radiator, so as to realize the reception of the first type of wireless signal by the radiator connected to the second radio frequency end. At this time, in the transmission process of the third electric signal or the fourth electric signal, the second matching circuit can adjust the impedance on the connecting line between the second radio frequency end and the radiator, so as to reduce the loss caused by the mismatch between the impedance of the radiator and the impedance of the second radio frequency end, thereby improving the transmission power of the third electric signal or the fourth electric signal.

[0153] In the embodiments of the present disclosure, the antenna module can adjust the frequency of the radiator receiving and transmitting the first type of wireless signal by arranging the second matching circuit and the isolation component at different positions of the connecting line between the radiator and the second radio frequency end, so as to improve the effect of the radiator receiving and transmitting the first type of wireless signal.

[0154] Exemplarily, as shown in Figure 6 In the case that the at least two radiators 11 include a first radiator 116 and a second radiator 117, the first impedance component 141 can include an inductive element L1 and an inductive element L2, the second impedance component 142 can include a capacitive element C1 and a capacitive element C2, the filter circuit 15 can include an inductive element L3 in series and a capacitive element C3 in parallel, and the second radio frequency end 13, the isolation component 16 and the second matching circuit 17 can also be two. At this time, the connecting line between the first radiator 116 and the second radio frequency end 13 can have an isolation component 16 and a second matching circuit 17 connected in series in sequence; similarly, the connecting line between the second radiator 117 and the second radio frequency end 13 can also have another isolation component 16 and another second matching circuit 17 connected in series in sequence. The connecting line between the first radiator 116 and the connecting node A can have the inductive element L1 connected in series, and the connecting line between the second radiator 117 and the connecting node A can also have the inductive element L2 connected in series; the connecting line between the connecting node A and the first radio frequency end 12 can have the capacitive element C2 and the inductive element L3 connected in series in sequence; the connecting line between the connecting node A and the capacitive element C2 can also have the capacitive element C1 connected in parallel, and the connecting line between the capacitive element C2 and the inductive element L3 can also have the capacitive element C3 connected in parallel.

[0155] Therefore, the antenna module in the embodiment of the present disclosure can reuse two radiators to transmit and receive NFC signals, which can not only realize better coverage effect of the antenna module for NFC signals, improve the performance of the antenna module for transmitting and receiving NFC signals, but also reduce the occupied space of the antenna module and improve the space utilization rate; and can reduce the influence of the radiator for transmitting and receiving the second type of wireless signals on the antenna performance for transmitting and receiving the first type of wireless signals, thereby realizing the compatibility between the two radiators for simultaneously transmitting and receiving the first type of wireless signals and the second type of wireless signals.
