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 extremely low-profile microstrip stacked dual-polarized base station antenna and an array, which belong to the field of antennas and specifically include a floor with square ring gaps etched, a radiation patch with cross-shaped slots, and a multi-branch feed structure. , cross-grooved stacked patches, and three-layer dielectric boards. On the one hand, the microstrip stacked dual-polarized antenna of the present invention introduces a novel multi-twig feeding structure and cross-shaped slotted stacked patches, which realizes balanced feeding of the antenna and expands the bandwidth of the antenna. On the other hand, the radiation patch with cross-shaped slots and the antenna floor etched with square ring gaps jointly suppress the coupling current between ports and improve the isolation of antenna ports. The antenna array of the present invention has the advantages of high port isolation, low profile, simple structure, easy processing and assembly, etc., and can be well applied to 5G new base stations.

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 ...
