Abstract

The invention relates to a unipolar sixteen-beam antenna for a mobile communication base station. The unipolar ten-beam antenna for the mobile communication base station comprises a metal floor, at least eight lines of parallel linear aerial arrays, at least eight first power dividers, at least eight second power dividers, a first Butler matrix feed network and a second Butler matrix feed network, wherein each line of linear aerial array consists of at least two same antenna radiation units. According to the antenna structure, eight beams with fixed orientation can be formed in the horizontal direction; two beams with fixed orientation can be formed in the vertical direction; small interference exists among the eight beams in the horizontal direction; and small interference exists between the two beams in the vertical direction. The sixteen-beam antenna manufactured according to the technical scheme has a good anti-interference effect and stable performance, is easy to assemble, and can effectively reduce cost and well meet the requirements of users.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a single-polarization sixteen-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 single-polarization sixteen-beam antenna for a mobile communication base station with a good anti-interference effect to address the above problems. [0005] A single-polarization sixteen-beam antenna for a mobile communication base station, comprising a metal floor, ...
