摘　　要：发射天线是地面电视传输系统的重要组成部分,是确保实际覆盖效果的关键,传统的电视发射天线以水平或垂直极化应用为主,往往不能兼顾接收端的各种接收场景。圆极化天线可以有效解决单一极化天线的覆盖缺陷,改善用户的接收效果。本文以安徽广播电视台大蜀山发射台圆极化天线安装为例,介绍了U波段圆极化天线的设计原理及调试、测试步骤,分析了圆极化天线的应用前景。Antenna is an important part of terrestrial television transmission system,and it is also the key to ensure actual coverage effect.Traditional TV transmitting antenna is mainly used in horizontal or vertical polarization,and it can’t adapt to all kinds of receiving scenarios.Circularly polarized antenna can effectively solve coverage defect of single polarized antenna and improve receiving effect of users.This paper takes the installation of circularly polarized antennas at Dashushan transmitting station of Anhui Broadcasting Corporation as an example,introduces design principle,debugging and testing steps of U-Band circularly polarized antennas,and analyzes application prospect of circularly polarized antenna.
