Abstract

The invention provides a radiation unit and a base station antenna. The radiation unit comprises a radiation arm group and a support balun. The radiation arm group comprises four radiation arms distributed in a central symmetry manner, a coupling slot extending along the circumferential direction is arranged between any two adjacent radiation arms, and each coupling slot comprises at least two coupling slot sections with different sizes. The supporting balun is electrically connected with the radiation arm group. According to the radiation unit, a coupling slot extending along the circumferential direction is arranged between any two adjacent radiation arms, and each coupling slot comprises at least two coupling slot sections with different sizes, so that the radiation unit has a good broadband matching characteristic and has excellent cross polarization ratio and front-to-back ratio indexes.

Description

technical field [0001] The invention relates to the technical field of mobile communication equipment, in particular to a radiation unit and a base station antenna. Background technique [0002] With the rapid development of the fifth-generation mobile communication technology, large-scale test network trials have entered the commercial stage, and major operators have started 5G coverage trials in some cities in China. 5G large-scale array antenna technology is the core technology of 5G, and the radiation unit is the core component of 5G antenna. The radiation unit itself needs to have good high-frequency radiation performance, cross polarization and front-to-back ratio indicators, so as to reduce signal interference and improve the signal quality of coverage. Contents of the invention [0003] The invention provides a radiation unit and a base station antenna, which are used to solve the problem in the prior art that the performance of the radiation unit is difficult to ...
