Abstract

The invention discloses a 5G circularly polarized multi-beam antenna, comprising a Butler feed network (1), a SIW connection part (2) and four waveguide aperture antennas (3). The waveguide aperture antenna (3) comprises a rectangle feed waveguide (4) and a rectangular radiation waveguide (5), the first end of the rectangular feed waveguide (4) serves as an input end of the waveguide aperture antenna and connected to the SIW connection part (2). The second end of the rectangular feed waveguide (4) is connected to the rectangular radiation waveguide (5); the rectangular feeding waveguide (4) isinternally provided with a rectangular metal wall (6), and the rectangular metal wall (6) divides the rectangular feed waveguide (4) into upper and lower parts. The rectangular metal wall (6) extendstoward the inside of the rectangular radiating waveguide (5) and gradually disappears in a triangular manner, and a triangular metal wall (7) is formed inside the rectangular radiation waveguide (5).The 5G circularly polarized multi-beam antenna has the advantages of simple structure, easy processing, and good circular polarization axis performance.

Description

technical field [0001] The invention relates to communication antennas, in particular to a 5G circularly polarized multi-beam antenna. Background technique [0002] With the rapid development of mobile communication technology, the number of wireless devices has increased significantly. Antenna is used as a transceiver converter for wireless communication signals, and its design will directly affect the overall performance of the wireless communication system, so antenna design plays an important role in the design of wireless communication systems. As the fifth-generation mobile communication technology, 5G has a peak theoretical transmission speed of tens of Gb / s. Its ultra-large-capacity data transmission and ultra-low delay provide technical support for the realization of emerging technologies such as driverless driving. It is expected that 5G will be launched in 2020. It will be commercially available in 2010, so the research on 5G antennas is particularly important. ...
