circularly polarized antenna

There are inherent contradictions among bandwidth, gain and miniaturization, on the basis of study on key technologies such as miniaturization and wide-band, the structure of circularly polarized antenna is innovated by digging a hole on medium board which solves contradictions among them.

从圆极化波产生理论出发,建立了三种分别采用双馈点馈电、微带馈电和探针馈电的圆极化天线的理论模型,对性能参数进行了优化,并对天线的关键尺寸进行分析,用仿真图形及表格清晰地描述了寄生单元的长宽、切角、辐射面大小等关键尺寸对于增益、轴比、阻抗等性能的影响规律,并由得出的规律对三种馈电方式的优缺点进行分析总结,得出结论:双馈点馈电的带宽良好但设计复杂,微带馈电的匹配网络简单但不易实现小型化,探针馈电使性能过于敏感。
