DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] The directional nouns involved in the embodiments of this application, such as "upper", "lower", "side", etc., are generally expressed in the form of Figure 1 The relative relationships shown in the figure are used as a reference, and these directional terms are used only to more clearly describe the relationship between structures, not to describe absolute directions. When the product is placed in different postures, the direction may change, for example, "up" and "down" may be interchangeable.

[0034] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those skilled in the art.

[0035] In order to make the technical solutions and advantages of the present application clearer, the implementation methods of the present application will be described in further detail below with reference to the accompanying drawings.

[0036] A first aspect of the present application provides an antenna assembly, such as Figure 1 As shown, the antenna assembly includes a first radiating branch 1 and a second radiating branch 2, with a gap between the first radiating branch 1 and the second radiating branch 2. The gap includes a first portion 100, a second portion 200, and a third portion 300. The first portion 100 and the second portion 200 both extend along the width of the first radiating branch 1. The third portion 300 extends along the length of the first radiating branch 1. The first portion 100 and the second portion 200 are respectively located at opposite ends of the third portion 300.

[0037] It is understood that the first radiating branch 1 and the second radiating branch 2 can participate in both signal radiation and reception. The gap can reduce the mutual influence between the two, which is conducive to improving the operational independence between the first radiating branch 1 and the second radiating branch 2. The first portion 100 and the second portion 200, which extend along the width direction of the first radiating branch 1 and are enclosed between the first radiating branch 1 and the second radiating branch 2, are conducive to improving the space utilization efficiency of the antenna assembly of the present application and reducing the size of the antenna assembly of the present application.

[0038] In summary, the antenna assembly of the present application can improve the structural compactness of the antenna assembly of the present application while maintaining the working performance of the first radiating branch 1 and the second radiating branch 2 and reducing the size of the antenna assembly by setting a gap extending in multiple directions between the first radiating branch 1 and the second radiating branch 2.

[0039] In some embodiments of the present application, the first radiation branch 1 includes a first radiator 11 and a second radiator 12, the second radiation branch 2 includes a third radiator 21 and a fourth radiator 22, the first part 100 is formed between the first radiator 11 and the fourth radiator 22, the second part 200 is formed between the third radiator 21 and the second radiator 12, and the third part 300 is formed between the second radiator 12 and the fourth radiator 22.

[0040] In related art, when an antenna assembly has multiple radiating branches, adjacent radiating branches generally cannot directly contact each other but must maintain a certain distance. Specifically, the two radiating branches do not overlap in a projection plane perpendicular to the width. Because the overall length of the antenna assembly is equal to the sum of the lengths of the two radiating branches plus the distance, this distance increases the size of the antenna assembly, specifically, making it longer. In the design process of electronic devices, their dimensions are generally fixed, so an overly long antenna assembly would conflict with the electronic device's structure.

[0041] The antenna assembly of the present application shortens the length of the antenna assembly of the present application by reducing the distance between the first radiation branch 1 and the radiation branch while enabling both to maintain their normal working performance.

[0042] The fourth radiator 22 partially overlaps with the first radiating branch 1 in a projection plane perpendicular to the width direction. This means that the overall length of the antenna assembly is the length of the first radiator 11, the length of the third radiator 21, the length of the third radiator 21, and the distance between the third radiator 21 and the first radiating branch 1 in the length direction, minus the length of the overlapping portion. Compared to the length of antenna assemblies in related arts, the antenna assembly of the present application can be shortened due to the presence of this portion that needs to be subtracted.

[0043] The second radiator 12 and the second radiating branch 2 partially overlap in a projection plane perpendicular to the width direction. This means that the overall length of the antenna assembly is the length of the first radiator 11, the length of the third radiator 21, plus the distance between the third radiator 21 and the first radiating branch 1 in the length direction, minus the length of the overlapping portion. Compared to the length of antenna assemblies in related arts, the antenna assembly of the present application can be shortened due to the presence of this portion.

[0044] In addition, the first portion 100 and the second portion 200 also increase the relative area between the first radiating branch 1 and the second radiating branch 2 , which is beneficial to improving the gripping ability.

[0045] In some embodiments of the present application, when the second radiator 12 protrudes from the first radiator 11 in the width direction, the overall width of the antenna assembly increases and occupies more space. Figure 1 As shown, the orthographic projection of the second radiator 12 on the first projection plane is located within the orthographic projection of the first radiator 11 on the first projection plane. The first projection plane is a plane perpendicular to the arrangement direction of the first radiator 11 and the second radiator 12 .

[0046] It can be understood that the orthographic projection of the second radiator 12 on the first projection plane is located within the orthographic projection of the first radiator 11 on the first projection plane, so that the second radiator 12 does not protrude from the first radiator 11 in the width direction, which is conducive to reducing the size of the antenna assembly of the present application in the width direction.

[0047] Optionally, the first radiator 11 and the second radiator 12 are arranged in parallel.

[0048] Optionally, the first radiator 11 and the second radiator 12 form an angle smaller than 90°.

[0049] In some embodiments of the present application, when the fourth radiator 22 protrudes from the third radiator 21 in the width direction, the overall width of the antenna assembly increases and occupies more space. Figure 1 As shown, the orthographic projection of the fourth radiator 22 on the second projection plane is located within the orthographic projection of the third radiator 21 on the second projection plane. The second projection plane is a plane perpendicular to the arrangement direction of the third radiator 21 and the fourth radiator 22 .

[0050] It can be understood that the orthographic projection of the fourth radiator 22 on the third projection plane is located within the orthographic projection of the third radiator 21 on the third projection plane, so that the fourth radiator 22 does not protrude from the third radiator 21 in the width direction, which is conducive to reducing the size of the antenna assembly of the present application in the width direction.

[0051] Optionally, the third radiator 21 and the fourth radiator 22 are arranged in parallel.

[0052] Optionally, the third radiator 21 and the fourth radiator 22 form an angle smaller than 90°.

[0053] In some embodiments of the present application, for the first radiation branch 1 and the second radiation branch 2, the capacitance between the two is affected by their relative areas. Figure 1 As shown, the side surface of the second radiator 12 facing the third radiator 21 is parallel to the side surface of the third radiator 21 facing the second radiator 12 .

[0054] It is understandable that such a configuration is beneficial to improving the uniformity of the electric field between the second radiator 12 and the third radiator 21 , thereby helping to maintain the capacitance of the first radiating branch 1 and the second radiating branch 2 in a relatively stable state.

[0055] In some of the embodiments of this application, Figure 1 As shown, the end surface of the second radiator 12 facing the fourth radiator 22 is parallel to the end surface of the fourth radiator 22 .

[0056] It can be understood that by setting the end face of the second radiator 12 facing the fourth radiator 22 to be parallel to the end face of the fourth radiator 22, the present application can improve the uniformity of the electric field between the second radiator 12 and the fourth radiator 22, which is beneficial to maintain the capacitance of the first radiating branch 1 and the second radiating branch 2 in a relatively stable state.

[0057] In some of the embodiments of this application, Figure 1 As shown, the end surface of the third radiator 21 facing the first radiator 11 is parallel to the end surface of the first radiator 11 .

[0058] It is understandable that such a configuration is beneficial to improving the uniformity of the electric field between the third radiator 21 and the first radiator 11 , thereby helping to maintain the capacitance of the first radiating branch 1 and the second radiating branch 2 in a relatively stable state.

[0059] In some of the embodiments of this application, Figure 2 As shown, the second radiator 12 has a plurality of first grooves 1201 . The plurality of first grooves 1201 are located on a side of the second radiator 12 facing the third radiator 21 and are spaced apart along the length direction of the second radiator 12 .

[0060] It can be understood that the first groove 1201 is conducive to forming cross-coupling between the first radiation branch 1 and the second radiation branch 2, and is conducive to maintaining the working performance of the antenna assembly of the present application.

[0061] In some of the embodiments of this application, Figure 2 As shown, the fourth radiator 22 has multiple second grooves 2201, which are located on the side of the fourth radiator 22 facing the second radiator 12 and are spaced apart along the length direction of the third radiator 21. The multiple first grooves 1201 and the multiple second grooves 2201 are staggered.

[0062] It can be understood that the second groove 2201 is conducive to forming cross-coupling between the first radiation branch 1 and the second radiation branch 2, and is conducive to maintaining the working performance of the antenna assembly of the present application.

[0063] In some of the embodiments of this application, Figure 3 As shown, the antenna assembly includes a power supply 3 , and the first radiation branch 1 and the second radiation branch 2 are both electrically connected to the power supply 3 .

[0064] It can be understood that the power supply 3 can supply power to the first radiation branch 1 and the second radiation branch 2 by being electrically connected to the first radiation branch 1 and the second radiation branch 2, so that the first radiation branch 1 and the second radiation branch 2 can radiate and receive signals.

[0065] In the embodiment of the present application, the power supply 3 may be a circuit board, a power supply or other components.

[0066] In some of the embodiments of this application, Figure 3 As shown, the power supply 3 includes a first power supply 31 and a second power supply 32 . The first power supply 31 is electrically connected to the first radiation branch 1 , and the second power supply 32 is electrically connected to the second radiation branch 2 .

[0067] It can be understood that by setting the first power supply 31 and the second power supply 32 to be electrically connected to the first radiating branch 1 and the second radiating branch 2 respectively, the antenna assembly of the present application can improve the working independence of the first radiating branch 1 and the second radiating branch 2, which is beneficial to the normal operation of the antenna assembly of the present application.

[0068] In the embodiment of the present application, the first power supply 31 can be electrically connected to the first radiating branch 1 by being electrically connected to the first radiator 11 , and the first power supply 31 can also be electrically connected to the first radiating branch 1 by being electrically connected to the second radiator 12 .

[0077] In some embodiments of the present application, the second radiation branch 2 serves as a frame of the electronic device.

[0078] It is understandable that the second radiation branches 2 serve as the frame of the electronic device, which helps to avoid the second radiation branches 2 being arranged in the electronic device, thereby reducing the internal space occupied by the second radiation branches 2 of the electronic device.
