Abstract

The invention relates to a dual-polarization three-beam antenna for a mobile communication base station, which comprises a metal floor board, at least three lines of mutually parallel linear aerial arrays, at least three first power dividers, at least three second power dividers, a first Butler matrix feed network and a second Butler matrix feed network. Each line of linear aerial arrays is composed of at least two same aerial radiation units. The antenna structure of the dual-polarization three-beam antenna can form three dual-polarization beams with fixed directing in the horizontal direction and a single dual-polarization beam with the fixed directing in the vertical direction, and interference between the three beams in the horizontal direction is small. The three-beam antenna made by using the technical scheme of the dual-polarization three-beam antenna is good in anti-interference effect, stable in performance, large in signal capacity, easy to install and capable of effectively reducing cost, and well meets user requirements.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a dual-polarized three-beam antenna for a mobile communication base station. Background technique [0002] With the rapid development of mobile communication technology and the sharp increase of mobile communication business volume, the coverage area of ​​mobile communication network is constantly expanding and perfecting. and become increasingly important. [0003] Traditional base station antennas communicate by generating a fixed wide beam in the coverage area, which reduces communication capacity due to interference. Contents of the invention [0004] In view of this, it is necessary to provide a dual-polarization three-beam antenna for mobile communication base stations with good anti-interference effect in view of the above problems. [0005] To achieve the above object, the present invention adopts the following technical solutions: [0006] A dual-polarized thre...
