Problems solved by technology

However, the coupling current between antenna ports is difficult to suppress, and the isolation of antenna ports can only rely on additional feed circuits
The complex feed circuit that is not easy to process and install not only increases the cost of the antenna, but also brings difficulties to the antenna impedance matching

Abstract

The invention discloses an ultra-low profile microstrip laminated dual-polarized base station antenna and an array thereof, and belongs to the field of antennas. The antenna particularly comprises a floor etched with a square ring gap, a cross slotted radiation patch, a multi-branch feed structure, a cross slotted stacked patch and three layers of dielectric plates. The novel multi-branch feed structure and the cross slotted stacked patch are introduced into the microstrip laminated dual-polarized antenna disclosed by the invention, so that balanced feed of the antenna is realized, and the bandwidth of the antenna is expanded; and moreover, the cross slotted radiation patch and the antenna floor etched with the square ring gap jointly suppress the coupling current between the ports, and the isolation of the antenna ports is improved. The antenna array has the advantages of being high in port isolation, low in profile, simple in structure, easy to process and assemble and the like, andcan be well applied to a 5G novel base station.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an extremely low-profile microstrip laminated dual-polarization base station antenna and an array. Background technique [0002] For the fifth-generation wireless mobile communication system, the base station is developing towards miniaturization and integration, which puts forward higher requirements on the physical size of the antenna. For a multi-antenna system, when the distance between the antennas is limited, if useless signals are coupled to the antenna ports, the antenna pattern will be distorted and the port isolation will be deteriorated, which will greatly affect the antenna matching performance, thereby reducing the performance of the antenna system. [0003] In a dipole base station antenna array, the coupling between antenna elements is mainly carried out in the form of space wave, which is difficult to suppress, and additional complex structures need to be added ...
