摘要:

设计了一种的小型化的双频双圆极化微带天线。对两个工作于主模的正方形贴片,通过采用对角切角方法,在北斗卫星导航系统的S频段实现右圆极化。通过蚀刻不对称臂U型槽结构,在北斗卫星导航系统的L频段实现左圆极化与小型化。其相比对普通的圆极化天线尺寸减小了24%,使用HFSS进行仿真,仿真结果表明本天线可以达到北斗系统对天线的各项指标要求。

关键词: 北斗卫星导航系统, 微带天线, 圆极化, 小型化

Abstract:

A novel miniaturized dual band dual circular polarization microstrip antenna is designed by using diagonal corner cutting method on a square patch operating in two main modes to realize right circular polarization in the S band of Beidou satellite navigation system and etching asymmetric arm U-shaped groove structure to achieve left circular polarization and miniaturization in the L band of Beidou satellite navigation system.Compare to the ordinary circularly polarized antenna,the antenna is reduced in size by 24%.The simulation was performed using HFSS simulation software,showing that the antenna meets the Beidou system requirements for antenna performance.

Key words: Beidou navigation satellite system;microstrip antenna;circular polarization;miniaturization
