[0233] Please also refer to image 3 , Figure 9 and Figure 22 , in the first embodiment, the antenna unit 100 has one radiating structure 20 , and the radiating structure 20 is located on one side of the ground structure 30 . Thus, the antenna unit 100 as a whole can radiate only one beam, that is, only one beam can be radiated by one radiation structure 20 .

[0234] Specifically, see Figure 9 , Figure 9 The size of the fan-shaped area C in is only schematically representing the radiation angle range of the main radiation direction of the projection of the beam radiated by the radiation structure 20 on the XOZ plane in this embodiment, and does not refer to Figure 9 The size of the fan-shaped area C shown in this embodiment limits the actual radiation angle range of the main radiation direction of the projection of the beam radiated by the radiation structure 20 on the XOZ plane. Such as Figure 9 As shown, it can be observed that in this embodiment, the antenna un...

[0285] Please also refer to Figure 5 , Figure 10 and Figure 36 , in the second embodiment, the same content as the above-mentioned first embodiment will not be repeated. The difference from the above-mentioned first embodiment is that the number of radiation structures 20 of the antenna unit 100 is two, and each radiation structure 20 is It is located on one side of the ground structure and is used to radiate a beam facing away from the side where the ground structure 30 is located.

[0286] Specifically, the two radiating structures 20 are respectively a first radiating structure 21 and a second radiating structure 22 , and the first radiating structure 21 and the second radiating structure 22 are located at two sides of the ground structure 30 . Since the first radiating structure 21 and the second radiating structure 22 can each radiate one beam, the antenna unit 100 has the characteristic of being able to radiate two beams.

[0287] It can be understood that the firs...

[0315] Please also refer to Figure 7 , Figure 11 , Figure 47 and Figure 48 , in the third embodiment, the same content as the above-mentioned second embodiment will not be repeated, and the difference from the above-mentioned second embodiment is that the first radiating structure 21 and the second radiating structure 22 are about the center line of the feeding part 33 I is rotationally symmetric, so that the beam radiated by the first radiating structure 21 is projected on the XOZ plane and the beam radiated by the second radiating structure 22 is projected on the XOZ plane on the center line I of the grounding structure 30. rotational symmetry at any point.

[0316] It can be understood that, in this embodiment, the feeding part 33 may be a symmetrical structure, while the first radiating structure 21 and the second radiating structure 22 have rotational symmetry. For example, the second radiating structure 22 can be obtained by rotating the first radiating structure...

Abstract

The technical scheme of the invention provides an antenna unit and electronic equipment. The antenna unit comprises N radiation plates and M grounding plates, wherein N and M are integers greater than 1; the N radiation plates are arranged at intervals along a first direction, and at least parts of any two adjacent radiation plates are overlapped, so that the N radiation plates are electrically connected with each other to form a radiation structure; the M grounding plates are also arranged at intervals along the first direction, and at least parts of any two adjacent grounding plates are overlapped, so that the M grounding plates are electrically connected with each other to form a grounding structure; and through cooperation of the radiation structure and the grounding structure, the radiation structure radiates an inclined wave beam opposite to the side where the grounding structure is located. According to the antenna unit and the electronic equipment, the negative influence of the metal frame on the antenna performance can be improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an antenna unit and electronic equipment. Background technique [0002] Millimeter wave technology is one of the core technologies of the fifth-generation mobile communication (5th-Generation, 5G) system, however, a higher frequency means greater transmission loss. Therefore, the 5G mmWave frequency band requires high-performance antenna arrays to meet the demand. The current millimeter-wave solution for terminals is to install several millimeter-wave antenna modules inside the mobile phone to achieve as wide a range of coverage as possible. However, due to the existence of the metal frame, it will have a negative impact on the antenna performance of some millimeter-wave antenna modules. How to improve the negative impact of the metal frame on the antenna performance is a problem that the industry continues to explore. Contents of the invention [0003] E...
