Problems solved by technology

In the past, the design of 5G antenna arrays mostly focused on the narrower 28GHz frequency band, which could not meet the requirements of the newly defined 5G millimeter wave frequency band. Therefore, it is necessary to provide a dual-band 5G antenna suitable for 37GHz and 39GHz array system

Embodiment 1

[0052] Please refer to figure 1 , image 3 and Figure 5 , this embodiment provides a dual-frequency array antenna for fifth-generation wireless communication, which can simultaneously include large bandwidths of two frequency bands of 37GHz and 39GHz, and has the advantages of high gain and radiation efficiency and good directivity, and can be used for mobile The equipment provides a millimeter-wave antenna array system for future 5G communications.

[0053] The dual-frequency array antenna includes a plurality of antenna elements 1 and a feed network 2 , and the antenna elements 1 are connected to the feed network 2 . Each antenna unit 1 includes a three-dimensional antenna carrier 4 and a PCB board 7; the surface of the three-dimensional antenna carrier 4 is surrounded by a first antenna radiator 5 and a second antenna radiator 6, which generate different resonance points respectively to realize dual frequency characteristics. Each resonance point is generated by differ...

Embodiment 2

[0062] Please refer to figure 2 , this embodiment further expands the structure of the dual-frequency antenna unit on the basis of the first embodiment.

[0063] Specifically, the bottom surface of the three-dimensional antenna carrier 4 of the antenna unit 1 is respectively provided with a first pad 11 and a second pad 12 corresponding to two ends of the second antenna radiator 6 . The PCB board 7 includes a PCB substrate 8 and a PCB floor 9; the upper surface (PCB substrate 8) of the PCB board 7 is respectively provided with a third pad 13 corresponding to the first pad 11 and the second pad 12 and the fourth pad 14, which are connected to the PCB floor 9 through the via hole 10; the two ends of the second antenna radiator 6 are respectively connected to the first pad 11 and the second pad 12, and the first pad The pad 11 and the second pad 12 are correspondingly connected to the third pad 13 and the fourth pad 14 .

[0064] The solid connection between the three-dimensio...

Embodiment 3

[0069] In this embodiment, on the basis of the first and second embodiments, the structure of the dual-frequency antenna unit is further expanded.

[0070] Specifically, the three-dimensional antenna carrier 4 can be a rectangular three-dimensional structure (a cube structure or a cuboid structure), or a columnar three-dimensional structure such as a cylinder; its material can be ceramics or other materials with good permittivity. In this embodiment, the three-dimensional antenna carrier 4 is a rectangular three-dimensional ceramic.

[0071] Since the size of the antenna radiator is determined by the permittivity ε of the antenna carrier r It is determined that the larger the dielectric constant of the carrier, the shorter the wavelength. In this embodiment, due to the use of permittivity ε r =8.0 ceramic material, its dielectric constant is relatively large, so the size of the antenna radiator can be reduced, the size of the antenna monomer will also be reduced, and the ove...

Abstract

The invention provides a double-frequency array antenna used for 5G (the fifth generation) wireless communication. An antenna monomer of the double-frequency array antenna comprises a first antenna radiating body and a second antenna radiating body which are arranged on the surface of a stereoscopic antenna carrier; the first antenna radiating body is a monopole antenna; the second antenna radiating body is around the first antenna radiating body, and is in ground connection with a PCB to form an annular antenna. The monopole antenna formed by the first antenna radiating body is used for direct feeding so as to generate resonance in a frequency range of about 36 to 40 GHz; the second antenna radiating body forming the annular antenna is coupled to the first antenna radiating body so as to generate another resonance in the frequency range of about 36 to 40 GHz, so that the antenna has double resonance. According to the array antenna disclosed by the invention, two 5G frequency bands of 37 GHz and 39 GHz defined by an FCC can be perfectly contained in the operation bandwidth of the array antenna; and meanwhile, the array antenna also has the characteristics of high radiation efficiency, high gain, good directionality, high stability and the like.

Description

technical field [0001] The invention relates to the field of antenna communication, in particular to a dual-frequency array antenna for fifth-generation wireless communication. Background technique [0002] In the field of modern communication, from the first generation mobile communication system 2G to the fourth generation mobile communication system 4G LTE, the main solution is the communication between people. However, the fifth generation (5G) mobile communication system, that is, 5G, It will solve the communication between people and things, things and things other than people and people, that is, to realize the desire to connect everything. The transmission rate of 5G will be more than 100 times that of 4G and support massive device connections, thereby making the Internet of Everything possible, and at the same time, it can realize automatic driving of cars, 3D virtual reality, telemedicine, etc. It can be predicted that the 5th generation mobile communication syste...
