摘要
通信系统中使用不同旋向的圆极化天线可以扩充通信容量,提高系统抗干扰能力。本文据此设计了一种双圆极化微带天线,能同时工作在收、发两个频段。天线利用单馈电法实现圆极化,利用双层贴片堆叠实现双频工作。最后借助三维电磁场仿真软件对天线进行仿真,并对仿真结果进行了分析。
The use of circular polarized antenna with different rotation direction can expand the transmission capacity and improve anti-interference capability of the communi- cation system. In this paper, a dual circular polarized antenna is designed which can both receive and send signals at the same time. The antenna is circular polarized by single feed method, and dual-frequency is achieved by stacked patches. Finally, the antenna is simulated with 3D electromagnetic simulation software and the result is analyzed.
