Abstract

The invention provides a 5G millimeter wave dual-polarization broadband wide-angle tight coupling array antenna. The antenna comprises an antenna array plate (1), a metal floor (5), a feed array (6) and a radiation unit (7). A first matching layer (2) covers above the antenna array plate, a second matching layer (3) and a third matching layer (4) cover below the antenna array plate, and the feed array and the metal floor are respectively positioned in the middle and below the third matching layer; the radiation unit is composed of a dual-polarization dipole arm and a dual-polarization coupling metal patch, the y-polarization dipole arm and the x-polarization coupling metal patch are arranged in the first matching layer, and the x-polarization dipole arm and the y-polarization coupling metal patch are arranged in the second matching layer; and the feed array is composed of a y polarization probe and an x polarization probe, the lower end of the feed array is connected with the floor, and the upper end of the feed array feeds the dipole arm in a coupled mode. The antenna is small in size, simple in structure, good in radiation efficiency, high in antenna gain and small in number of feed ports, and can be used for 5G millimeter wave band communication.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a dual-polarized wide-bandwidth angular tightly coupled array antenna, which can be used for 5G millimeter wave band communication. Background technique [0002] With the increasing development of modern communication systems, mobile communication technology has played an increasingly important role in social development and era change. It took only a few decades for the communication network to transition from the original first-generation 1G mobile communication technology to the current fifth-generation 5G mobile communication technology. Millimeter wave has become a candidate frequency band for 5G communication system due to its advantages of high directivity, high resolution and abundant spectrum resources. The Ministry of Industry and Information Technology of my country approved the development of 5G system technology research and development tests, and the h...
