[0036] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of structures consistent with some aspects of the present disclosure as detailed in the appended claims.

[0037] Figure 1 is a schematic diagram of the structure of an antenna module provided according to an exemplary embodiment Figure 1 ,like Figure 1 As shown, the antenna module 10 may include:

[0038] A first radiator 11 having a first feeding point 111;

[0039] The second radiator 12 has a gap 13 between it and the first radiator 11;

[0040] A ground return circuit 14, one end of which is connected between the first feeding point 111 and the break 13, and the other end of which is grounded;

[0041] When the first radiator 11 and the second radiator 12 are coupled to transmit and receive wireless signals, the current of the first radiator 11 , the current of the second radiator 12 and the current of the ground return circuit 14 can form a current loop A.

[0042] The antenna module provided in the embodiment of the present disclosure can be set in a terminal device. The antenna module can be used to send 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.

[0043] Specifically, the application scenario of the terminal device where the antenna module provided by the embodiment of the present disclosure is located may include a wireless communication scenario.

[0044] Exemplarily, the wireless communication scenario may be a multi-device scenario. For example, in a scenario of configuring a network for a smart device, a terminal device may perform multi-machine interaction with other electronic devices through a router or a base station to complete the configuration of the network for the smart device.

[0045] See also Figure 2 , the wireless communication network environment 200 includes: a terminal device 201A, other electronic devices 201B, a wireless LAN (Wireless Fidelity, Wi-Fi) access point 202, a cellular base station 203 and a network 204. Here, when the terminal device 201A and other electronic devices 201B use a wireless LAN or a cellular network to send and receive wireless signals, the Wi-Fi and cellular networks can be switched 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 present disclosure, Figure 2 In the network environment shown, the Wi-Fi connection is stopped upon receiving an instruction from a cellular base station to perform wireless transmission; and the Wi-Fi connection is restored upon receiving an instruction to stop the cellular base station from performing wireless transmission.

[0046] The antenna module provided by the present disclosure can be applied in the field of wireless signal transmission. By changing the frequency of the wireless signal received and sent by the radiator, the receiving and sending frequency band of the wireless signal is improved, thereby optimizing the performance of wireless communication.

[0047] In the disclosed embodiment, the first radiator radiates navigation positioning signals and wireless network communication signals, and the second radiator radiates mobile communication signals. For example, the first radiator can radiate L1 signals and Wi-Fi 2.4G signals, and the second radiator can radiate signals of the N77 frequency band of the fifth generation mobile communication technology (5G).

[0048] Here, the L1 signal radiated by the first radiator can be a navigation positioning signal with a carrier frequency of the L1 frequency band in the Global Positioning System (GPS). The center frequency of the L1 signal can be 1575.42 megahertz (MHz), with high signal strength and good penetration. The Wi-Fi 2.4G signal radiated by the first radiator can refer to a wireless LAN signal operating in the 2.4 gigahertz (GHz) frequency band. The 2.4G frequency band is one of the commonly used frequency bands in Wi-Fi technology. The 2.4G frequency band has strong penetration and a wide coverage range, and is suitable for environments such as homes and offices. The signal of the N77 frequency band radiated by the second radiator can be a frequency band in the New Radio (NR) signal, and the frequency range of the N77 frequency band can be 3.3GHz to 4.2GHz.

[0049] It should be noted that the specific types of the first radiator and the second radiator can be set according to the actual application scenario, and the embodiments of the present disclosure are not limited. For example, the first radiator and the second radiator can both be formed by the frame of the terminal device; or the first radiator and the second radiator can both be made by the FPC process; or the first radiator and the second radiator can both be made by LDS.

[0050] In some embodiments, the center frequency of the wireless signal received and sent by the second radiator is greater than the center frequency of the wireless signal received and sent by the first radiator. Exemplarily, when the wireless signal received and sent by the second radiator is a 5G+N77 signal and the wireless signal received and sent by the first radiator is an L1 signal, the center frequency of the wireless signal received and sent by the second radiator may be 3.75 GHz, while the center frequency of the wireless signal received and sent by the first radiator may be 1.5754 GHz; when the wireless signal received and sent by the second radiator is a 5G+N77 signal and the wireless signal received and sent by the first radiator is a Wi-Fi 2.4G signal, the center frequency of the wireless signal received and sent by the second radiator may be 3.75 GHz, while the center frequency of the wireless signal received and sent by the first radiator may be 2.4 GHz.

[0051] It should be noted that the specific shapes of the first radiator and the second radiator can also be set according to the actual application scenario, and the embodiments of the present disclosure are not limited. For example, the shape of the first radiator can be a straight line or an L-shaped shape, and the shape of the second radiator can also be a straight line or an L-shaped shape.

[0052] In the embodiment of the present disclosure, the first feeding point may be a connection point between a feeding circuit of the first radiator and the first radiator; the first radiator and the second radiator are spaced apart, that is, there is a gap between the first radiator and the second radiator.

[0053] The ground return circuit may be a circuit for grounding the first radiator; one end of the ground return circuit may be connected between the first feeding point and the break, and the other end may be connected to the ground wire.

[0054] Here, the return-to-ground circuit may include a capacitor element, one end of which is connected between the first feeding point and the break, and the other end is grounded. Alternatively, the return-to-ground circuit may also include two capacitor elements and an inductor element, one end of one capacitor element is connected between the first feeding point and the break, and the other end is grounded; one end of the other capacitor element is connected between the first feeding point and the break, and the other end is connected to the inductor element, and the inductor element is grounded, etc., and the embodiments of the present disclosure are not limited thereto.

[0055] It can be understood that the first radiator is grounded between the first feeding point and the break through the ground return circuit, which can stimulate a high-order circulating current mode between the first radiator and the second radiator; that is, when the first radiator and the second radiator are coupled to send and receive wireless signals, the current of the first radiator, the current of the second radiator and the current of the ground return circuit can form a current loop, which can change the radiation characteristics of the first radiator and the second radiator, so that the radiation patterns of the first radiator and the second radiator are superimposed to enhance the radiation intensity of the first radiator and the second radiator in different radiation directions, thereby optimizing the radiation pattern performance of the antenna module.

[0056] It should be noted that the specific position of the first feeding point on the first radiator can be set according to the actual application scenario, as long as one end of the return circuit is connected between the first feeding point and the fracture, and the embodiment of the present disclosure does not limit it. For example, the shape of the first radiator is a straight line, and the first feeding point can be located at the end of the first radiator away from the fracture; or the shape of the first radiator is L-shaped, and the first feeding point can be located at the corner of the L-shaped, etc.

[0057] The antenna module provided by the embodiment of the present disclosure includes: a first radiator having a first feeding point; a second radiator having a gap between the first radiator and the second radiator; a ground return circuit, one end of which is connected between the first feeding point and the gap, and the other end is grounded; wherein, when the first radiator and the second radiator are coupled to send and receive wireless signals, the current of the first radiator, the current of the second radiator and the current of the ground return circuit can form a current loop. Through the antenna module proposed in the present invention, one end of the ground return circuit is connected between the first feeding point and the break of the first radiator and the other end of the ground return circuit is grounded. When the first radiator is coupled with the second radiator to send and receive wireless signals, the current of the first radiator, the current of the second radiator and the current of the ground return circuit can form a current loop. The current loop can change the radiation characteristics of the first radiator and the second radiator to improve the radiation intensity of the first radiator and the second radiator in different radiation directions, thereby optimizing the directional pattern performance of the antenna module; at the same time, the first radiator and the second radiator can send and receive wireless signals after coupling, so that the wireless signals sent and received by the first radiator and the second radiator can cover a wider area, effectively improving the transmission distance and reception quality of the wireless signals sent and received by the antenna module.

[0058] Figure 3 is a schematic diagram of the structure of an antenna module provided according to an exemplary embodiment Figure 2 ,like Figure 3 As shown, in the antenna module provided by the embodiment of the present disclosure, the first radiator 11 further has a first return point 112 located between the first feeding point 111 and the break 13; the return circuit 14 includes:

[0059] The return capacitor 141 has one end connected to the first return point 112 and the other end connected to the ground, and is used to ground the first radiator 11 .

[0060] In the embodiment of the present disclosure, the first return point may be a connection point between the first radiator and the return circuit; the return capacitor may be a device in the return circuit that grounds the first radiator.

[0061] It can be understood that connecting a return capacitor between the first return point of the first radiator and the ground wire can stimulate a high-order circulating current mode between the first radiator and the second radiator; that is, by setting the return capacitor, when the first radiator and the second radiator are coupled and wireless signals are received and sent, the current of the first radiator, the current of the second radiator and the current on the return capacitor can form a current loop, and the electromagnetic fields between the first radiator and the second radiator will interact to change the radiation characteristics of the first radiator and the second radiator, and the directional patterns of the first radiator and the second radiator will be superimposed to enhance the radiation intensity of the first radiator and the second radiator in different radiation directions, thereby optimizing the directional pattern performance of the antenna module.

[0062] It should be noted that the specific number of the return capacitors can be set according to the actual application scenario, and the embodiments of the present disclosure do not limit it. For example, there can be one return capacitor, which is connected between the first return point and the ground wire; or there can be multiple return capacitors, which are connected in parallel between the first return point and the ground wire.

[0063] In some embodiments, Figure 3 As shown, the length of the first radiator 11 between the first return point 112 and the break 13 is smaller than the length of the first radiator 11 between the first feeding point 111 and the first return point 112 .

[0064] In this way, the length of the first radiator between the first return point and the break on the first radiator can be made shorter than the length of the first radiator between the first feeding point and the first return point, so that when the first radiator and the second radiator are coupled and wireless signals are received and sent, the current of the first radiator, the current of the second radiator and the current of the return circuit can form a current loop, thereby effectively improving the radiation intensity of the first radiator and the second radiator in different radiation directions, thereby optimizing the directional pattern performance of the antenna module.

[0065] In the embodiment of the present disclosure, the first return point on the first radiator may be close to the break between the first radiator and the second radiator, and the first feeding point on the first radiator may be far away from the break between the first radiator and the second radiator.

[0066] It should be noted that the specific positions of the first return point and the first feeding point on the first radiator can be set according to the actual application scenario, as long as the length of the first radiator between the first return point and the break on the first radiator is less than the length of the first radiator between the first feeding point and the first return point, the embodiment of the present disclosure is not limited.

[0067] Exemplarily, when the shape of the first radiator is in the shape of a straight line, the distance between the first return point and the break on the first radiator may be smaller than the distance between the first feeding point and the first return point; when the shape of the first radiator is in the shape of an L, the first radiator may include a first radiating branch close to the break and a second radiating branch connected to the first radiating branch, in which case the first return point may be located on the first radiating branch, and the second return point may be located on the second radiating branch, that is, the length of the first radiator between the first return point and the break on the first radiator is smaller than the length of the first radiator between the first feeding point and the first return point.

[0068] In some embodiments, Figure 3 As shown, the direction of the current on the first radiator 11 and the second radiator 12 in the current loop A flows from the first return point 112 to the second radiator 12 .

[0069] In this way, the current direction located on the first radiator and the second radiator in the current loop can flow from the first return point to the second radiator, so that the first radiator can better assist the second radiator in sending and receiving wireless signals, thereby effectively improving the performance of the second radiator in sending and receiving wireless signals.

[0070] Here, when the first radiator is located on the left side of the second radiator, that is, the first radiator is located on the left side of the break and the second radiator is located on the right side of the break, the current direction in the current loop can be clockwise, and the current direction at this time is from the first return point on the first radiator to the second radiator; when the first radiator is located on the right side of the second radiator, that is, the first radiator is located on the right side of the break and the second radiator is located on the left side of the break, the current direction in the current loop can be counterclockwise, and the current direction at this time is also from the first return point on the first radiator to the second radiator.

[0071] In the disclosed embodiment, a return-to-ground capacitor can be connected between the first return point of the first radiator and the ground wire, so that when the first radiator is coupled with the second radiator and transmits and receives wireless signals, the current of the first radiator, the current of the second radiator and the current on the return-to-ground capacitor can form a current loop, and the current loop can change the radiation characteristics of the first radiator and the second radiator to enhance the radiation intensity of the first radiator and the second radiator in different radiation directions, thereby optimizing the directional pattern performance of the antenna module; at the same time, wireless signals can be transmitted and received after the first radiator and the second radiator are coupled, so that the wireless signals transmitted and received by the first radiator and the second radiator can cover a wider area, effectively improving the transmission distance and reception quality of the wireless signals transmitted and received by the antenna module.

[0072] In some embodiments, Figure 3 As shown, the first radiator 11 includes at least two radiating branches, and the first feeding point 111 is located at the angle formed by two adjacent radiating branches.

[0073] In this way, by setting the first feeding point on the first radiator at the angle formed by two adjacent radiating branches, it can be better ensured that when the first radiator and the second radiator are coupled to each other and transmit and receive wireless signals through the return circuit, the current of the first radiator, the current of the second radiator and the current on the return capacitor can form a current loop, thereby better optimizing the directional pattern performance of the antenna module.

[0074] It can be understood that the first feeding point on the first radiator including at least two radiating branches is set at the angle formed by two adjacent radiating branches, and the first return point is set near the break; at this time, the return circuit connected to the first return point can better stimulate the high-order circulating current mode between the first radiator and the second radiator, that is, when the first radiator and the second radiator are coupled and send and receive wireless signals, the current of the first radiator, the current of the second radiator and the current of the return circuit can form a current loop to change the radiation characteristics of the first radiator and the second radiator, so that the radiation patterns of the first radiator and the second radiator are superimposed, thereby improving the radiation intensity of the first radiator and the second radiator in different radiation directions, and better optimizing the radiation pattern performance of the antenna module.

[0075] In some embodiments, Figure 3 As shown, the second radiator 12 has a second feeding point 121 and a second return point 122 spaced apart from the second feeding point 121;

[0076] The second return point 122 is located at an end of the second radiator 12 away from the break 13 , and the second feeding point 121 is located between the break 13 and the second return point 122 .

[0077] In this way, the second return point on the second radiator can be set at the end of the second radiator away from the break, and the second feeding point can be set between the break and the second return point, so that when the first radiator and the second radiator are coupled, the wireless signal can be better transmitted and received. The current of the first radiator, the current of the second radiator and the current of the return circuit can form a current loop to optimize the directional performance of the antenna module.

[0078] In the embodiment of the present disclosure, the second feeding point may be a connection point between a feeding circuit of the second radiator and the second radiator; and the second return point may be a connection point between the second radiator and the ground wire.

[0079] It should be noted that the specific positions of the second return point and the second feeding point on the second radiator can be set according to the actual application scenario, as long as the second feeding point is located between the break and the second return point, and the embodiment of the present disclosure does not limit it. For example, the shape of the second radiator is a straight line, the second return point can be located at the end of the second radiator away from the break, and the second feeding point can be located at any position between the break and the second return point; or, the shape of the second radiator is L-shaped, the second feeding point can be located at the corner of the L-shape, and the second return point can be located at the end of the second radiator away from the break, in which case the second feeding point is also located between the break and the second return point.

[0080] In related technologies, such as Figure 4 As shown, the antenna feed point 22 on the first antenna 21 in the traditional antenna module 20 is close to the gap between the first antenna 21 and the second antenna 23, while the grounding point on the first antenna 21 is far away from the gap; at this time, a current loop cannot be formed between the first antenna and the second antenna, and the directional performance of the antenna module cannot be optimized. At present, it is usually necessary to add an antenna such as Laser-Direct-structuring (LDS) or Flexible Printed Circuit (FPC) to the original frame antenna of the mobile phone for coupling to optimize the directional performance of the antenna. However, this solution requires the additional connection of a new antenna, which will occupy the internal space of the mobile phone and affect the miniaturization of the terminal device.

[0081] Based on this, the present disclosure provides an antenna module, such as Figure 5 As shown, by setting the first return point 112 on the first radiator 11 between the first feeding point 111 and the break 13, that is, the first return point 112 is closer to the break 13 than the first feeding point 111. Figure 6As shown, the current signal analysis of the first radiator and the second radiator receiving and sending wireless signals shows that, by connecting the ground return circuit between the first return point and the ground wire of the first radiator, when the first radiator and the second radiator are coupled and sending and receiving wireless signals, the current of the first radiator, the current of the second radiator and the current of the ground return circuit can form a current loop A, and the current loop A can change the radiation characteristics of the first radiator and the second radiator to enhance the radiation intensity of the first radiator and the second radiator in different radiation directions, thereby optimizing the directional pattern performance of the antenna module.

[0082] For example, see Figure 7a , Figure 7a The dotted line in the directional diagram shown represents the directional diagram of the traditional antenna module in the 5G CH36 frequency band when the terminal device is in both portrait and landscape scenarios. The solid line represents the directional diagram of the antenna module in the 5G CH36 frequency band when the terminal device is in both portrait and landscape scenarios. At this time, regardless of whether the terminal device is in portrait or landscape scenarios, the directional diagram performance of the antenna module is better than that of the traditional antenna module. Compared with the traditional antenna module, the antenna module can improve the directional diagram by an average of 58%. See Figure 7b , Figure 7b The dotted line in the shown radiation pattern represents the radiation pattern corresponding to the traditional antenna module under the 5G CH149 frequency band when the terminal device is in both portrait and landscape scenarios. The solid line represents the radiation pattern corresponding to the antenna module under the 5G CH149 frequency band when the terminal device is in both portrait and landscape scenarios. At this time, regardless of whether the terminal device is in portrait or landscape scenarios, the radiation pattern performance of the antenna module is better than that of the traditional antenna module. Compared with the traditional antenna module, the antenna module can improve the radiation pattern by an average of 58%.

[0083] Furthermore, the first radiator and the second radiator can transmit and receive wireless signals after coupling, so that the wireless signals transmitted and received by the first radiator and the second radiator can cover a wider area, effectively improving the transmission distance and reception quality of the wireless signals transmitted and received by the antenna module. At the same time, by changing the positional relationship between the first return point and the first feeding point on the first radiator, the antenna module can be optimized while reducing the internal space occupied by the antenna module in the terminal device, thereby miniaturizing the terminal device.

[0084] A terminal device provided in an embodiment of the present disclosure at least includes:

[0085] Conductive housing;

[0086] The antenna module of the first aspect;

[0087] Different parts of the conductive shell are reused as the first radiator and the second radiator of the antenna module.

[0088] In the disclosed embodiment, the conductive shell may be a metal part having a conductive area; the conductive shell may be an outer frame of a terminal device such as a mobile phone, used to support functional components inside the mobile phone.

[0089] The antenna module proposed in the present disclosure can be set on a conductive shell; or, different parts of the conductive shell are used as antennas in a mobile phone to send and receive wireless signals, that is, they are multiplexed as the first radiator and the second radiator of the antenna module of an embodiment of the present disclosure.

[0090] In some embodiments, the conductive housing includes a first conductive edge and a second conductive edge and a third conductive edge that are arranged opposite to each other, the first conductive edge is connected between the second conductive edge and the third conductive edge; a portion of the first conductive edge and the second conductive edge are reused as a first radiator, and another portion of the first conductive edge and the third conductive edge are reused as a second radiator. In this way, by reusing the conductive edges of the conductive housing as the first radiator and the second radiator, the layout of other functional components of the terminal device can be better coordinated, and the space occupied by the antenna module in the terminal device can be reduced.

[0091] Exemplarily, the shape of the conductive shell may be a rectangle, that is, the conductive shell may include opposite long sides and opposite short sides; in this case, the first conductive side may be a short side, such as the top of a mobile phone, and the second conductive side and the third conductive side may be opposite long sides of the rectangle. The first radiator proposed in the present disclosure may be located at a short side and a long side connected to the short side, and the second radiator may be located at the short side and another long side opposite to the long side.

[0092] In the embodiment of the present disclosure, by multiplexing different conductive edges of the conductive shell as the first radiator and the second radiator, the space occupied by the antenna module in the terminal device is reduced and the flexibility of the layout of other functional components of the terminal device is improved.

[0093] It should be noted that the “first” and “second” in the embodiments of the present disclosure are only for the convenience of description and distinction and have no other specific meanings.

[0094] Figure 8 1 is a block diagram of a terminal device according to an exemplary embodiment.
