Abstract

A novel printed antenna with broadband circular polarization (CP) characteristics is presented. The antenna design is based on a recently developed uniplanar quasi-Yagi. The antenna measures VSWR<2 and AR<3 dB in the frequency range from 3.40 to 6.34 GHz (60.4%). The bandwidth is more than twice that of the best planar CP antenna to our knowledge. The measured dual-linear pattern at 5 GHz shows that the antenna has excellent CP performance, with its AR below 6 dB over a wide range of scan angles (/spl plusmn/80/spl deg/) from the mainbeam direction.

一种新型宽带圆极化印刷天线

提出了一种具有宽带圆极化特性的新型印刷天线。天线的设计是基于最近发展的一种准八木天线。在3.40 ~ 6.34 GHz频率范围内，VSWR<2, AR<3 dB(60.4%)。其带宽是目前已知的最佳平面CP天线的两倍以上。在5 GHz频段测量的双线方向图表明，该天线具有良好的CP性能，在较宽的扫描角度(/spl plusmn/80/spl度/)范围内，其AR值低于6 dB。
