摘要

对单馈圆极化谐振腔天线(RCA)进行了高轴比带宽的研究。探讨了在介质谐振器天线(DRA)上放置金属层的设计方法。通过深入的参数研究，优化了AR-BW。该天线能够提供高轴向比以及匹配带宽(超过12.6%)，波束宽度超过28°。

New circularly polarized resonance cavity antenna

Single feed circularly polarized resonance cavity antenna (RCA) has been studied for high axial ratio bandwidth (AR-BW). Metallic superstrate layer placed over a dielectric resonator antenna (DRA) is explored for such design. Optimized AR-BW has been achieved through intensive parametric study. The antenna is capable to deliver high axial ratio as well as matching bandwidth (over 12.6%) with more than 28° of beamwidth.
