The present invention proposes a 5G millimeter-wave dual-polarized wide-bandwidth angular tightly coupled array antenna. It includes an antenna array board (1), a metal floor (5), a feeding array (6) and a radiation unit (7). The top of the antenna array board is covered with a first matching layer (2), the bottom is covered with a second matching layer (3) and a third matching layer (4), and the feed array and the metal floor are respectively located in the middle and below the third matching layer; The radiating unit is composed of a dual-polarized dipole arm and a dual-polarized coupling metal patch, and the y-polarized dipole arm and the x-polarized coupled metal patch are placed in the first matching layer, and the x-polarized dipole The arm and the y-polarized coupling metal patch are placed in the second matching layer; the feeding array is composed of a y-polarized probe and an x-polarized probe, the lower end of which is connected to the ground, and the upper end couples and feeds the dipole arm. The invention has the advantages of small size, simple antenna structure, good radiation efficiency, high antenna gain, and few feeding 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...
