DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0037] An embodiment of the present disclosure provides an antenna module. Figure 1 Schematic diagram of the antenna module provided in the embodiment of the present disclosure. Figure 1 As shown, the antenna module includes a carrier 1 and a conductive member 2. The conductive member 2 covers the first surface of the carrier 1 and gradually forms a cavity antenna with the carrier 1. The conductive member 2 includes a first plate 21, which is opposite to the first surface of the carrier 1 and has a window 23 provided on the first plate 21.

[0038] In the antenna module provided by the disclosed embodiments, the conductive member 2 and the carrier 1 form a cavity antenna, suitable for electronic devices using a full metal housing or circuit board as the carrier. A window 23 is provided on the first plate 21 of the conductive member 2, which faces the carrier 1. This window 23 is used to modify the current distribution within the antenna module, thereby reducing the size of the antenna module while still meeting the antenna's required radiation frequency, thereby optimizing the internal structure of the electronic device.

[0039] To make the technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be described in further detail below with reference to the accompanying drawings.

[0040] like Figure 1 As shown, the antenna module provided by the embodiment of the present disclosure includes a carrier 1 and a conductive member 2. The conductive member 2 covers the first surface of the carrier 1 and is connected to the carrier 1 to form a cavity antenna. The area of ​​the first surface of the carrier 1 is not less than the area of ​​the projection of the conductive member 2 on the first surface of the carrier 1. The conductive member 2 and the carrier 1 both include a conductive material. For example, the conductive member 2 and the carrier 1 are both made of metal or alloy materials such as aluminum and copper. The conductive member 2 and the carrier 1 form a cavity antenna, so that the antenna module provided by the embodiment of the present disclosure is suitable for electronic devices with an all-metal casing.

[0041] See also Figure 1 The conductive member 2 includes a first plate 21, which is opposite to the first surface of the carrier 1. The first plate 21 is in the shape of a flat plate, and the plane on which the first plate 21 is located is parallel to the first surface of the carrier 1. The cavity of the cavity antenna is located between the first plate 21 and the carrier 1, and a window 23 is provided on the first plate 21. The first plate 21 of the conductive member 2, which is opposite to the carrier 1, is provided with a window 23. The window 23 is used to allow the current in the cavity antenna to flow through the conductor around the window 23, thereby changing the current distribution of the antenna module. After testing, for conductive members 2 of the same size, the radiation frequency of the antenna module without the window 23 is greater than the radiation frequency of the antenna module with the window 23. It can be seen from this that, while meeting the required radiation frequency of the antenna, the antenna module with the window 23 can have a smaller size. That is, the antenna module provided by the embodiment of the present disclosure has a smaller size, which can reduce the space occupied by the antenna module and is conducive to optimizing the internal structure of the electronic device.

[0042] In some embodiments of the present disclosure, Figure 1 As shown, the first plate 21 is flat, the plane where the first plate 21 is located is parallel to the first surface of the carrier 1, and the distance between the plane where the first plate 21 is located and the first surface of the carrier 1 is no more than 5 mm.

[0043] In some embodiments of the present disclosure, Figure 1 As shown, the conductive member 2 also includes a second plate 22, which is located between the first plate 21 and the first surface of the carrier 1, and the opposite ends of the second plate 22 are respectively connected to the first plate 21 and the first surface of the carrier 1. The second plate 22 is used to connect the first plate 21 and the carrier 1, and together with the first plate 21 and the carrier 1, form a cavity antenna. It should be noted that the opposite ends of the second plate 22 refer to one end of the second plate 22 close to the first plate 21 and one end close to the carrier 1. Moreover, the second plate 22 is perpendicular to the first surface of the carrier 1 and the plane where the first plate 21 is located.

[0044] In some embodiments of the present disclosure, Figure 1 As shown, the side of the conductive member 2 near the opening 24 of the cavity antenna is used to connect to the feed circuit, while the side of the conductive member 2 away from the opening 24 is used for grounding. The opening 24 can adjust the current distribution on the conductive member 2, directing current from the feed position to the ground position. Optionally, the first edge 211 of the first plate 21 is adjacent to the opening 24.

[0045] Figure 2 This is a top view of an antenna module provided by an embodiment of the present disclosure. Figure 2 When looking down at the conductive member 2 , the second plate 22 is U-shaped, and the opening of the U-shaped second plate 22 is the opening 24 of the cavity antenna.

[0046] It should be noted that the second plate 22 and the first plate 21 can be integrally formed, with one plate being bent to form the conductive member 2. Alternatively, the second plate 22 is bent into a U-shape and welded to the flat first plate 21.

[0047] In some embodiments of the present disclosure, Figure 2 As shown, the feeding position 25 of the cavity antenna is located at the first edge 211 .

[0048] Alternatively, see Figure 2 The first plate body 21 is rectangular, and the first plate body 21 has a second edge 212 opposite to the first edge 211, and a third edge 213 and a fourth edge 214 located between the first edge 211 and the second edge 212. The first edge 211 and the second edge 212 are the long sides of the rectangular first plate body 21, and the third edge 213 and the fourth edge 2142 are the short sides of the rectangular first plate body 21.

[0049] Figure 3 A top view of a conductive member 2 provided in an embodiment of the present disclosure. In some embodiments of the present disclosure, such as Figure 3 As shown, the distance d between the window 23 and the first edge 211 is not less than 10% of the width W of the first plate 21 , and the distance c between the window 23 and the second edge 212 is not less than 20% of the width W of the first plate 21 .

[0050] In some embodiments of the present disclosure, Figure 3 As shown, the distance a between the window 23 and the third edge 213 is not less than 10% of the length L of the first plate 21 , and the distance b between the window 23 and the fourth edge 214 is not less than 25% of the length L of the first plate 21 .

[0051] In the conductive member 2 , one side of the second plate 22 is connected to the second edge 212 , the third edge 213 and the fourth edge 214 of the first plate 21 , and the other side of the second plate 22 is connected to the first surface of the carrier 1 .

[0052] Alternatively, as Figure 3 As shown, the window 23 is rectangular, and each edge of the window 23 is parallel to each edge of the first plate 21. Specifically, the long side of the rectangular window 23 is parallel to the first edge 211 and the second edge 212, and the short side of the rectangular window 23 is parallel to the third edge 213 and the fourth edge 214.

[0053] In other embodiments, the first plate 21 and the window 23 may be other shapes, such as a circle, a parallelogram, a trapezoid, etc., and the shapes of the first plate 21 and the window 23 may be the same or different, which is not specifically limited in the embodiment of the present disclosure.

[0054] For example, see Figure 3 The first plate 21 provided in the embodiment of the present disclosure has a length L of 80 mm and a width W of 40 mm. The distance between the side of the first plate 21 away from the carrier 1 and the side of the carrier 1 away from the conductive member 2 is 3 mm. The window 23 is a square with a side length of 18 mm. The distance d between the window 23 and the first edge 211 is 5 mm, the distance c between the window 23 and the second edge 212 is 27 mm, the distance a between the window 23 and the third edge 213 is 10 mm, and the distance b between the window 23 and the fourth edge 214 is 52 mm.

[0055] Alternatively, as Figure 2As shown, the edge of the window 23 near the third edge 213 is aligned with the feed position 25. Alternatively, the projection of the window 23 on the first edge 211 is located between the feed position 25 and the fourth edge 214. The arrangement of the window 23 enables the current of the cavity antenna to be primarily distributed between the window 23 and the first edge 211 and the fourth edge 214, as well as between the window 23 and the third edge 213.

[0056] For example, see Figure 2 , the window 23 can be located in the first position 231, the second position 232, or the third position 233. The distance between the feeding position 5 and the third edge 213 is 10 mm. The windows 23 located in the first position 231, the second position 232, and the third position 233 are all squares with a side length of 18 mm. When the window 23 is located in the first position 231, the distance a between the window 23 and the third edge 213 is 10 mm, and the distance d between the window 23 and the first edge 211 is 5 mm. When the window 23 is located in the second position 232, the distance a between the window 23 and the third edge 213 is 15 mm, and the distance d between the window 23 and the first edge 211 is 5 mm. When the window 23 is located in the third position 233, the distance a between the window 23 and the third edge 213 is 20 mm, and the distance d between the window 23 and the first edge 211 is 5 mm.

[0057] Figure 4 A top view of another antenna module provided in an embodiment of the present disclosure. In some embodiments of the present disclosure, such as Figure 4 As shown, the projection area of ​​the window 23 on the first surface of the carrier 1 is no greater than 40% of the projection area of ​​the first plate 21 on the first surface of the carrier 1. An excessively large area of ​​the window 23 may affect the radiation frequency and current distribution of the cavity antenna, resulting in the radiation frequency of the cavity antenna failing to reach the desired frequency band.

[0058] For example, for a first plate 21 with a length L of 80 mm and a width W of 40 mm, the maximum area of ​​the window 23 is 1280 mm. 2 When the window 23 is rectangular, the distance a between the window 23 and the third edge 213 is at least 10 mm, the distance d between the window 23 and the first edge 211 is at least 5 mm, the distance c between the window 23 and the second edge 212 is at least 8 mm, and the distance b between the window 23 and the fourth edge 214 is at least 20 mm.

[0059] For example, Figure 4As shown, window 23 can be located in fourth position 234, fifth position 235, or sixth position 236. The distance between feed position 5 and third edge 213 is 10 mm. The windows 23 located in fourth position 234, fifth position 235, and sixth position 236 have different areas. When window 23 is located in fourth position 234, window 23 is a square with a side length of 12 mm, a distance a between window 23 and third edge 213 is 10 mm, and a distance d between window 23 and first edge 211 is 5 mm. When window 23 is located in fifth position 235, window 23 is a square with a side length of 15 mm, a distance a between window 23 and third edge 213 is 10 mm, and a distance d between window 23 and first edge 211 is 5 mm. When window 23 is located in sixth position 236, window 23 is a square with a side length of 18 mm, a distance a between window 23 and third edge 213 is 10 mm, and a distance d between window 23 and first edge 211 is 5 mm.

[0060] Figure 5 for Figure 2 The standing wave diagram of the antenna module is shown in FIG. Figure 5 As shown, when window 23 is at the first position 231, the antenna standing wave is located at the position of the 001 curve, the center frequency is 1.76 GHz, and the antenna radiation efficiency is -10 dB. When window 23 is at the second position 232, the antenna standing wave is located at the position of the 002 curve, the center frequency is 1.82 GHz, and the antenna radiation efficiency is -8.4 dB. When window 23 is at the third position 233, the antenna standing wave is located at the position of the 003 curve, the center frequency is 1.99 GHz, and the antenna radiation efficiency is -8.4 dB. When window 23 is not set, the antenna standing wave is located at the position of the 004 curve, the center frequency is 2 GHz, and the antenna radiation efficiency is -8.8 dB. It can be seen that when the window 23 is not provided, the current of the cavity antenna is concentrated near the feeding position 25. When the window 23 is provided, more current is distributed in the area near the third edge 213 and the fourth edge 214. That is, the window 23 enables the current to flow through the first plate 21 around the window 23, avoiding excessive current concentration near the feeding position 25, thereby changing the current distribution of the antenna module and the radiation frequency of the cavity antenna. Figure 5 It can be seen that for conductive members 2 of the same size, the radiation frequency of the antenna module without windows 23 is greater than the radiation frequency of the antenna module with windows 23 at the first position 231, the second position 232, and the third position 233. Therefore, while meeting the required radiation frequency of the antenna, the antenna module with windows 23 can have a smaller size. In other words, the antenna module provided by the embodiments of the present disclosure has a smaller size, which can reduce the space occupied by the antenna module and facilitate optimization of the internal structure of the electronic device.

[0061] Figure 6 for Figure 4 The standing wave diagram of the antenna module is shown in FIG. Figure 6 As shown, when the window 23 is at the fourth position 234, the antenna standing wave is at the position of the 004 curve, the center frequency is 2 GHz, and the radiation efficiency of the antenna is -9.9 dB. When the window 23 is at the fifth position 235, the antenna standing wave is at the position of the 005 curve, the center frequency is 1.82 GHz, and the radiation efficiency of the antenna is -9.6 dB. When the window 23 is at the sixth position 236, the antenna standing wave is at the position of the 006 curve, the center frequency is 1.76 GHz, and the radiation efficiency of the antenna is -9.5 dB. Based on Figure 6 It can be seen that for a conductive member 2 of the same size, when the distance between the window 2 and the first edge 211 and the third edge 213 is constant, the larger the area of ​​the window 23, the more current is distributed in the area near the third edge 213 and the fourth edge 214, and the more obvious the change in the current distribution caused by the window 23. Because an antenna with a larger window 23 has a lower radiation frequency, the size of the antenna module can be reduced to a greater extent. Therefore, while meeting the required radiation frequency of the antenna, an antenna module with a larger window 23 can have a smaller size. That is, the antenna module provided by the embodiment of the present disclosure has a smaller size, which can reduce the space occupied by the antenna module and is conducive to optimizing the internal structure of the electronic device.

[0062] In addition, an embodiment of the present disclosure also provides an electronic device. Figure 7 A schematic diagram of an electronic device provided in an embodiment of the present disclosure, such as Figure 7 As shown, the electronic device includes an antenna module, wherein the carrier 1 is a shell of the electronic device, or the carrier 1 is a circuit board of the electronic device.

[0063] In the electronic device provided by the embodiment of the present disclosure, the conductive member 2 forms a cavity antenna with the housing or circuit board of the electronic device. For electronic devices with a full metal housing, the cavity antenna can effectively improve the signal strength of the electronic device. A window 23 is provided on the first plate 21 opposite to the carrier 1 of the conductive member 2. The window 23 is used to allow the current in the cavity antenna to flow through the conductor around the window 23, thereby changing the current distribution of the antenna module. When the radiation frequency required by the antenna is met, the antenna module provided with the window 23 can have a smaller size, that is, the antenna module of the electronic device provided by the embodiment of the present disclosure has a smaller size, which reduces the internal space of the electronic device occupied by the antenna module.

[0064] Optionally, the electronic device further includes a camera module 3 and a circuit board, wherein the camera module 3 is connected to the carrier 1. The circuit board is electrically connected to the antenna module.
