| 摘 要： | 针对多频段信号卫星接收天线，采用层叠微带和多级Wilkinson功分移相馈电网络结构，运用二点和四点馈电技术实现圆极化，设计了一种可用于3种卫星导航终端的新型多频段圆极化微带贴片天线。天线可工作于北斗一代的S频段，北斗二代的Bl和B2频段，Galileo的E5和E2-L1—E1频段以及GPS的u和L5频段。对天线模型及版图进行仿真的结果表明，该天线在各工作频段内反射损耗均小于-10dB，所有工作频段都具有良好的右旋圆极化性能和辐射特性。

| Abstract: | A novel multi-band circular polarization stacked microstrip antenna used in three kinds of satellite navigation systems is designed. It has been realized by three stacked patches, which are fed by two and four pins. The amplitude and phase relationship between the two and four pins to maintain circular polarization is obtained by wide band Wilkinson 90° and 180° hybrid coupler. The antenna can work at GPS L1 and L5 bands,Beidou No. 1 S band,Beidou No. 2 B1 and B2 bands and Galileo E5 and E2- L1-E1 bands. The simulation of the layout results show that this antenna has good circular polarization characteristic ,the S11 characteristic is less than- 10 dB in the whole operation bands. |
