[0034] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0035] like Figure 1 As shown, a related embodiment proposes an antenna module, including a metal frame A1, the metal frame A1 includes a radiation arm A11, the radiation arm A11 is provided with a feeding point A12 and a grounding point A13, the feeding point A12 is connected to the signal, and the grounding point A13 is grounded.

[0036] The signal is fed into the radiation arm A11 via the feeding point A12 to stimulate a radiation current on the radiation arm A11, thereby achieving radiation of the signal and satisfying the communication requirements of the antenna module.

[0037] At the same time, when the antenna module is subject to the extreme stacking environment, the distance between the radiating arm A11 and other metal parts A2 is too close. The radiating arm A11 is prone to couple current on the metal part A2 when radiating signals. The coupled current causes a freely radiated signal to be generated on the metal part A2, thereby affecting the radiation of the signal on the radiating arm A11, resulting in reduced radiation efficiency and radiation performance of the antenna module, making it difficult to meet usage requirements.

[0038] To solve the above technical problems, Figure 2 As shown, the embodiment of the present disclosure proposes an antenna module 1, including a metal frame 11 and a first conductive member 12, the metal frame 11 includes a first radiating arm 111, the first radiating arm 111 is provided with a first feeding point 112 and a first grounding point 113, the first feeding point 112 is connected to a first signal, the first grounding point 113 is grounded, the first end of the first conductive member 12 is connected to a metal member 21 close to the first radiating arm 111, the second end of the first conductive member 12 is grounded, and the first conductive member 12 is used to reduce the coupling current on the metal member 21.

[0039] It can be understood that the first signal is fed into the first radiating arm 111 using the first feeding point 112 to stimulate a radiation current on the first radiating arm 111, thereby realizing the radiation of the first signal and satisfying the communication requirements of the antenna module 1. At the same time, since the first end of the first conductive member 12 is connected to the metal member 21 and the second end of the first conductive member 12 is grounded, the coupling current on the metal member 21 can be introduced into the ground using the first conductive member 12, thereby effectively reducing the first signal freely radiated on the metal member 21 and improving the radiation efficiency of the first signal on the first radiating arm 111, thereby improving the radiation performance of the antenna module 1 and satisfying the use requirements.

[0040] Moreover, since the provision of the first conductive member 12 can effectively improve the radiation efficiency of the first signal on the first radiation arm 111, the antenna module 1 can make the first radiation arm 111 and the metal member 21 close to each other while maintaining a relatively high radiation efficiency, thereby being able to adapt to the increasingly compact and complex stacking inside the terminal device, thereby facilitating the development of the terminal device towards miniaturization, diversified functions, and the like.

[0041] It should be noted that the metal frame 11 is made of metal material, which is the structure of the edge of the metal middle frame. The metal frame 11 not only has greater structural strength, better texture, etc., but also can use its own metal material to radiate antenna signals. The specific type of the metal frame 11 can be set according to actual needs and is not limited to this. For example, the metal frame 11 can be rectangular, circular, etc.

[0042] The first radiation arm 111 is part or all of the metal frame 11 . The specific type of the first radiation arm 111 can be set according to actual needs and is not limited thereto.

[0043] The first conductive member 12 is used to conduct the coupling current in the metal member 21 to the ground to reduce the coupling current on the metal member 21. The specific type of the first conductive member 12 can be set according to actual needs and is not limited to this. For example, the first conductive member 12 can be a conductive cloth, and when the length, width and height of the middle frame are 45.5 mm, 36.2 mm and 5 mm respectively, the length, width and thickness of the first conductive member 12 can be 12.15±0.5 mm, 2±0.2 mm, and 0.035±0.004 mm respectively.

[0044] The metal part 21 is a device made of metal material. The specific type of the metal part 21 can be set according to actual needs and is not limited to this. For example, the metal part 21 can be a screen 2, microphone, speaker, motor, battery 14, etc. in the terminal device.

[0045] like Figure 3As shown, in some embodiments, the metal frame 11 further includes a second radiation arm 114, and the second radiation arm 114 is provided with a second feeding point 115 and a second grounding point 116, the second feeding point 115 is connected to the second signal, and the second grounding point 116 is grounded.

[0046] It can be understood that the second signal is fed into the second radiating arm 114 using the second feeding point 115 to stimulate a radiation current on the second radiating arm 114, thereby achieving radiation of the second signal and satisfying the communication requirements of the antenna module 1. At the same time, since the metal frame 11 includes both the first radiating arm 111 and the second radiating arm 114, and the metal part 21 is close to the first radiating arm 111, the distance between the second radiating arm 114 and the metal part 21 is also close, causing the second radiating arm 114 to be easily affected by the metal part 21.

[0047] Therefore, by setting the first conductive part 12, the coupling current on the metal part 21 can be introduced into the ground by the first conductive part 12, thereby effectively reducing the second signal freely radiated on the metal part 21 and improving the radiation efficiency of the second signal on the second radiation arm 114, thereby improving the radiation performance of the antenna module 1 and meeting the use requirements.

[0048] Moreover, since the provision of the first conductive member 12 can effectively improve the radiation efficiency of the first signal on the first radiation arm 111 and the radiation efficiency of the second signal on the second radiation arm 114, the antenna module 1 can make the metal member 21 and the first radiation arm 111 and the second radiation arm 114 close to each other while maintaining a relatively high radiation efficiency, thereby being able to adapt to the increasingly compact and complex stacking inside the terminal device, thereby facilitating the development of the terminal device towards miniaturization, diversified functions, and the like.

[0049] It should be noted that the second radiation arm 114 is part or all of the metal frame 11 , and the specific type of the second radiation arm 114 can be set according to actual needs and is not limited thereto.

[0050] like Figure 4 As shown, in some embodiments, the antenna module 1 also includes a printed circuit board 13 (Printed Circuit Board, PCB), the printed circuit board 13 is arranged on the metal frame 11, and the metal frame 11 is located around the printed circuit board 13, the first output end of the printed circuit board 13 is connected to the first feeding point 112, the first grounding end of the printed circuit board 13 is connected to the first grounding point 113, the second output end of the printed circuit board 13 is connected to the second feeding point 115, the second grounding end of the printed circuit board 13 is connected to the second grounding point 116, and the third grounding end of the printed circuit board 13 is connected to the second end of the first conductive member 12.

[0051] It can be understood that the printed circuit board 13 uses the first output end to feed the first signal to the first feeding point 112, so that the first signal stimulates a radiation current on the first radiation arm 111, thereby realizing the radiation of the first signal. At the same time, the printed circuit board 13 uses the second output end to feed the second signal to the second feeding point 115, so that the second signal stimulates a radiation current on the second radiation arm 114, thereby realizing the radiation of the second signal, thereby meeting the communication requirements of the antenna module 1.

[0052] At the same time, since the first grounding end of the printed circuit board 13 is connected to the first grounding point 113, and the second grounding end of the printed circuit board 13 is connected to the second grounding point 116, the third grounding end of the printed circuit board 13 is connected to the second end of the first conductive member 12, the first radiation arm 111, the second radiation arm 114 and the first conductive member 12 are respectively grounded through the printed circuit board 13, thereby ensuring that the antenna module 1 radiates the first signal and the second signal efficiently.

[0053] It should be noted that the printed circuit board 13 is used to provide a feeding signal to the first radiation arm 111 and the second radiation arm 114, and provide a grounding point for the first radiation arm 111, the second radiation arm 114 and the first conductive member 12. The specific type of the printed circuit board 13 can be set according to actual needs and is not limited to this. For example, the printed circuit board 13 can be a mainboard in a terminal device. The printed circuit board 13 is set on a metal middle frame by screw fixation, adhesive fixation, etc. The printed circuit board 13 is provided with circuits, chips, motors, etc. The control chip in the printed circuit board 13 provides a first signal to the first radiation arm 111 and a second signal to the second radiation arm 114. At the same time, the shielding cover in the printed circuit board 13 provides a grounding point for the first radiation arm 111, the second radiation arm 114 and the first conductive member 12.

[0054] like Figure 3 As shown, in some embodiments, the metal frame 11 includes a top 117, a bottom 118, and a first side 119 and a second side 110 located between the top 117 and the bottom 118 and opposite to each other, the first feeding point 112 is arranged at one end of the top 117 close to the first side 119, the first grounding point 113 is arranged at one end of the top 117 close to the second side 110, the second feeding point 115 is arranged at one end of the bottom 118 close to the second side 110, the second grounding point 116 is arranged at one end of the bottom 118 close to the first side 119, and the first conductive member 12 is close to the second side 110.

[0055] It can be understood that since the first feeding point 112 is arranged at one end of the top 117 close to the first side 119, and the first grounding point 113 is arranged at one end of the top 117 close to the second side 110, when the first feeding point 112 is fed with the first signal, the first radiating arm 111 is stimulated to emit a radiation current along the direction from the first side 119 to the second side 110, thereby ensuring that the first radiating arm 111 radiates the first signal efficiently.

[0056] Since the second feeding point 115 is arranged at one end of the bottom 118 close to the second side 110, and the second grounding point 116 is arranged at one end of the bottom 118 close to the first side 119, when the second feeding point 115 is fed with the second signal, the second radiation arm 114 is stimulated to emit a radiation current in the direction from the second side 110 to the first side 119, thereby ensuring that the second radiation arm 114 radiates the second signal efficiently.

[0057] Since the first conductive element 12 is close to the second side 110 , the first conductive element 12 does not occupy the space at the top 117 , the bottom 118 and the first side 119 of the metal frame 11 , thereby ensuring efficient integration of the antenna module 1 in the terminal device.

[0058] It should be noted that the relative position of the metal frame 11 in the terminal device can be set according to actual needs, and there is no limitation on this. For example, when the terminal device is a watch, the top 117 of the metal frame 11 can be the 12 o'clock position of the terminal device, the bottom 118 of the metal frame 11 can be the 6 o'clock position of the terminal device, the first side 119 of the metal frame 11 can be the 3 o'clock position of the terminal device, and the second side 110 of the metal frame 11 can be the 9 o'clock position of the terminal device. At the same time, the first feeding point 112 is close to the 1 o'clock position of the terminal device, the second feeding point 115 is close to the 7 o'clock position of the terminal device, the first grounding point 113 is close to the 11 o'clock position of the terminal device, and the second grounding point 116 is close to the 5 o'clock position of the terminal device.

[0059] Among them, the position of the first radiating arm 111 can be the area between the first grounding point 113 and the second grounding point 116 on the metal frame 11, and the first feeding point 112 is located in this area, the position of the second radiating arm 114 can be the area between the second grounding point 116 and the first grounding point 113 on the metal frame 11, and the second feeding point 115 is located in this area, the first side 119 of the metal frame 11 can be installed with the crown of the terminal device, the top 117 of the metal frame 11 can be installed with the first strap 5 of the terminal device, and the bottom 118 of the metal frame 11 can be installed with the second strap 6 of the terminal device.

[0060] like Figure 4As shown, in some embodiments, the antenna module 1 further includes a battery 14 , which is disposed on the printed circuit board 13 , and an output end of the battery 14 is connected to an input end of the printed circuit board 13 .

[0061] It is understandable that, by providing the battery 14 , the printed circuit board 13 can be powered, thereby ensuring that the printed circuit board 13 feeds power to the first radiation arm 111 and the second radiation arm 114 , thereby ensuring stable operation of the antenna module 1 .

[0062] It should be noted that the battery 14 is used to supply power to the printed circuit board 13. The specific type of the battery 14 can be set according to actual needs and is not limited to this. When the antenna module 1 is applied to a terminal device, the battery 14 can also supply power to the screen 2, microphone, speaker, motor, etc. of the terminal device.

[0063] In some embodiments, the first signal is a GNSS (Global Navigation Satellite System) antenna signal; and / or the second signal is a BT (Bluetooth) antenna signal.

[0064] It can be understood that the GNSS antenna signal is fed into the first radiation arm 111 using the first feeding point 112 to stimulate a radiation current on the first radiation arm 111, thereby realizing the radiation of the GNSS antenna signal. At the same time, the BT antenna signal is fed into the second radiation arm 114 using the second feeding point 115 to stimulate a radiation current on the second radiation arm 114, thereby realizing the radiation of the BT antenna signal, thereby meeting the communication requirements of the antenna module 1.

[0065] Moreover, through the provision of the first conductive part 12, the coupling current on the metal part 21 can be introduced into the ground by the first conductive part 12, thereby effectively reducing the freely radiated GNSS antenna signals and BT antenna signals on the metal part 21, and improving the radiation efficiency of the GNSS antenna signals and BT antenna signals on the second radiation arm 114, thereby improving the radiation performance of the antenna module 1 and meeting the usage requirements.

[0066] like Figure 4 As shown, in some embodiments, the antenna module 1 further includes a flexible printed circuit board 15 (Flexible Printed Circuit board, FPC), a first end of the flexible printed circuit board 15 is connected to a first end of the first conductive member 12 , and a second end of the flexible printed circuit board 15 is connected to the metal member 21 .

[0067] It can be understood that since the first end of the flexible circuit board 15 is connected to the first end of the first conductive member 12, and the second end of the flexible circuit board 15 is connected to the metal member 21, the first conductive member 12 and the metal member 21 can be connected through the flexible circuit board 15, thereby ensuring the stable conduction of the coupling current on the metal member 21 to the ground, and meeting the requirements of extreme stacking inside the terminal device.

[0068] It should be noted that the specific type of the flexible circuit board 15 can be set according to actual needs and is not limited to this. For example, when the metal part 21 is a metal layer in the screen 2, the flexible circuit board 15 can be used to connect the screen 2 and the printed circuit board 13.

[0069] like Figure 4 As shown, the embodiment of the present disclosure further proposes a terminal device, including the antenna module 1 and the metal component 21 as in the embodiment of the present disclosure, wherein the metal component 21 is close to the metal frame 11 of the antenna module 1 .

[0070] It can be understood that the first signal is fed into the first radiating arm 111 using the first feeding point 112 to stimulate a radiation current on the first radiating arm 111, thereby realizing the radiation of the first signal and satisfying the communication requirements of the antenna module 1. At the same time, since the first end of the first conductive member 12 is connected to the metal member 21 and the second end of the first conductive member 12 is grounded, the coupling current on the metal member 21 can be introduced into the ground using the first conductive member 12, thereby effectively reducing the first signal freely radiated on the metal member 21 and improving the radiation efficiency of the first signal on the first radiating arm 111, thereby improving the radiation performance of the antenna module 1 and satisfying the use requirements.

[0071] Moreover, since the provision of the first conductive member 12 can effectively improve the radiation efficiency of the first signal on the first radiation arm 111, the antenna module 1 can make the first radiation arm 111 and the metal member 21 close to each other while maintaining a relatively high radiation efficiency, thereby being able to adapt to the increasingly compact and complex stacking inside the terminal device, thereby facilitating the development of the terminal device towards miniaturization, diversified functions, and the like.

[0072] It should be noted that the specific type of the terminal device can be set according to actual needs and is not limited to this. For example, the terminal device can be a bracelet, a watch, a mobile phone, a tablet computer, a car terminal, etc.

[0073] Compared with the antenna module 1 in the related embodiment, the antenna module 1 in this embodiment only adds a first conductive member 12, thereby avoiding changes to the original structure in the terminal device and without sacrificing the functions of other modules in the terminal device.

[0074] like Figure 4As shown, in some embodiments, the terminal device further includes a screen 2 , the screen 2 is disposed on the metal frame 11 , and the screen 2 includes a metal part 21 .

[0075] It can be understood that since the first end of the first conductive member 12 is connected to the metal member 21 and the second end of the first conductive member 12 is grounded, the coupling current on the metal member 21 can be introduced into the ground by the first conductive member 12, thereby effectively reducing the first signal freely radiated on the metal member 21, improving the radiation efficiency of the first signal on the first radiation arm 111, and further improving the radiation performance of the antenna module 1 to meet the usage requirements.

[0076] It should be noted that the screen 2 is used for display of terminal equipment, etc. The specific type of the screen 2 can be set according to actual needs and is not limited to this. For example, the screen 2 may include a glass cover layer, a metal layer, an adhesive layer, etc., wherein the metal layer is the metal part 21.

[0077] like Figure 4 As shown, in some embodiments, the terminal device further includes a second conductive member 3 , a first end of the second conductive member 3 is connected to the screen 2 , and a second end of the second conductive member 3 is connected to the printed circuit board 13 of the antenna module 1 .

[0078] It can be understood that since the first end of the second conductive member 3 is connected to the screen 2, and the second end of the second conductive member 3 is connected to the printed circuit board 13 of the antenna module 1, the printed circuit board 13 and the screen 2 can be connected through the second conductive member 3, thereby facilitating the transmission of image signals, fingerprint signals, etc. between the printed circuit board 13 and the screen 2, thereby ensuring the function of the screen 2.

[0079] It should be noted that the specific type of the second conductive member 3 can be set according to actual needs and is not limited to this. For example, the second conductive member 3 may include a connecting wire between the third output terminal of the printed circuit board 13 and the input terminal of the screen 2, and may also include a connecting wire between the input terminal of the printed circuit board 13 and the output terminal of the screen 2, and may also include a connecting wire between the fourth ground terminal of the printed circuit board 13 and the metal layer of the screen 2. When the second conductive member 3 includes a connecting wire between the fourth ground terminal of the printed circuit board 13 and the metal layer of the screen 2, it can be understood that the first conductive member 12 and the wire are connected in parallel, that is, by setting the first conductive member 12, the impedance between the metal layer of the screen 2 and the ground is reduced.

[0080] like Figure 4 As shown, in some embodiments, the terminal device also includes a back cover 4, which is disposed on a side of the metal frame 11 away from the screen 2, and the printed circuit board 13 and the battery 14 of the antenna module 1 are located between the screen 2 and the back cover 4.

[0081] It can be understood that, through the provision of the rear shell 4, protection of various components in the terminal device is achieved, thereby reducing interference of the external environment on the terminal device and ensuring stable operation of the terminal device.

[0082] It should be noted that the rear shell 4 and the screen 2 are respectively arranged on both sides of the metal frame 11 and form a closed accommodating cavity, and the metal middle frame, printed circuit board 13, battery 14, first conductive member 12, second conductive member 3, etc. are all located in the accommodating cavity. Among them, a heart rate detection module, a speaker, etc. can also be arranged on the rear shell 4.

[0083] like Figure 3 As shown, in some embodiments, the terminal device further includes a first strap 5 and a second strap 6 , the first strap 5 is disposed on the top 117 of the metal frame 11 , and the second strap 6 is disposed on the bottom 118 of the metal frame 11 .

[0084] It can be understood that, by providing the first strap 5 and the second strap 6, it is easier to wear the terminal device and make the use of the terminal device more convenient.

[0085] It should be noted that the specific types of the first strap 5 and the second strap 6 can be set according to actual needs and are not limited to this. For example, when the terminal device is a watch, the first strap 5 and the second strap 6 are watch straps.

[0086] Based on the simulation of the antenna module 1 of this embodiment, the following is obtained: Figure 5 and Figure 6 The simulation diagram shown.

[0087] in, Figure 5 The ordinate is the radiation efficiency, the abscissa is the frequency, the first curve represents the first radiation arm 111 in the antenna module 1 of this embodiment, and the second curve represents the first radiation arm 111 in the antenna module of the related embodiment.
