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。A novel miniaturized dual band dual circular polarization microstrip antenna is designed by using di- agonal comer 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 cir- cular 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 sim- ulation software, showing that the antenna meets the Beidou system requirements for antenna performance.
