| 摘 要： | 分析了平面等角螺旋天线的研究方法，设计了工作于0．4～2GHz的双臂平面等角螺旋天线。根据天线的平衡结构和宽带特性，设计了一种阻抗为指数渐变的微带线-平行双线形式的宽带巴伦，并可采用50Ω同轴电缆馈电。测量结果显示天线和巴伦表现出良好的圆极化和宽频带特性。

| Abstract: | Analyzed the research technique of the planar equiangular spiral antenna. In this work the design and test of a wideband antenna and its match circuit is presented. The antenna is a double-armed planar equiangular spiral antenna and fed by 50 ohm coaxial-cable. To match the balance structure and the wideband character of the antenna, its balun is microstrip line-parallel wire which is exponentially gradual type. Test result shows that antenna and balun present good circular polarization and wideband character. |
