中小型调频广播电台电波极化方式的讨论

The Discussion of the Different Polarizations of the Electromagnetic Wave from FM Broad casting Station

目前调频广播收音机广泛使用鞭状拉杆接收天线，不少听众处于靠近地面的移动状态，为了改善听众接收效果，本文讨论了中小型调频广播电台发射电波的极化方式，对水平极化、圆极化和垂直极化的优缺点进行了理论和实测的分析对比，以采用垂直极化较好．

With the widely application of whip antenna to FM radio receivers,to im-prove it's receiving effect,the paper discuses the different polarizations of the electro mag-netic wave from FM broad casting stations, it's better to radiate vertically polarised wavefor midle scale FM broad casting stations.
