| 摘 要： | 介绍一种新型宽带圆极化微带天线。该天线采用同轴线单点馈电，通过在圆形贴片上开C型缝的方法，实现了圆极化并辰宽了阻抗带宽；采用层叠结构，使上下两层贴片谐振于相近的频率，从而显著提高了天线的轴比带宽和阻抗带宽。仿真结果显示，该新型天线工作于X波段时，3dB轴比带宽为13．9％，VSWR〈2的阻抗带宽达到35．4％。结果证明，在贴片上开C型缝是实现圆极化的有效方法。

| Abstract: | A novel single-layer single-patch broadband Circularly Polarized(CP) microstrip antenna is introduced.The antenna is fed by a single coaxial probe.It can not only creat circularly polarized but also enhance the standing wave ratio by embedding a C shape slot in the patch.The simulated results show that the 3 dB axial ratio of this patch antenna is up to 13.9% and the 2 V standing wave ratio bandwidth(VSWR<2) is up to 35.4%.It is demonstrated through the simulated resultes that circularly polarized can be ac... |
