| 摘 要： | 圆极化全向天线由于其自身的性能特点，在现代无线应用中越来越受到广泛的关注。提出一种宽轴比带宽的L频段圆极化微波贴片天线，该天线有上下两个介质层，下层微带馈线耦合馈电，接地面蚀刻十字交叉缝隙以帮助实现圆极化和改善上层贴片的耦合度。设计结果显示，该天线3dB轴比带宽可以达到3．5％（1.0231．060GHz），在有效带宽内天线增益高于5．68dBi，在中心频率点（1．04GHz）天线的前后瓣比高于20dB。

| Abstract: | The circularly polarized omni-directional antennas are paid more and more attention in the modern wireless applications because of its specific performance characteristics.A L-band circularly polarized microstrip patch antenna working in wide axial ratio bandwidth is presented.This antenna has two substrates and is fed by a feed line on the top of the lower substrate.A cross slot is etched on the bottom of the lower substrate,which helps to realize circular polarization and couple more energy to the patch o... |
