圆极化和水平极化天线在调频广播的应用对比分析

Application Comparison of Circular Polarization and Horizontal Polarization Antennas in FM Broadcasting

本文介绍了水平极化和圆极化两种天线的特点和参数,通过当地发射台安装的两副不同极化天线,在相同环境条件下收测其覆盖场强,将收测的数据进行对比,分析了两副天线的覆盖效果,并据此对调频广播发射天线的更新换代提出建议。

This paper introduces characteristics and parameters of horizontal polarization and circular polarization antennas.Two antennas with different polarizations installed at local transmitting station are used to measure coverage field strength under same environmental conditions.Measured data sre compared,and coverage effects of two antennas are analyzed.based on this,recommendations are proposed for the replacement of FM broadcast transmitting antenna.
