| 摘 要： | 超高音速(Ma≥5)雷达天线罩位于飞行器的侧面,一方面起到保护天线罩后面GPS通信天线及接收机的作用,另一方面起到热防、透波的作用,但天线罩的引入势必对GPS天线的辐射和散射特性发生影响。基于几何光学的射线追踪法,分析了GPS平板天线罩的传输系数,利用Ansoft HFSS软件对GPS L1波段微带圆形贴片天线进行加罩仿真分析,给出性能良好的GPS天线罩结构。

| Abstract: | Super sonic set up in the side of the aircraft,on the one hand it protects the GPS communications antenna and receiver which are behind the antenna window,on the other hand it plays a role of hot defense and the wave penetration.So the introduction of the random is bound to affect the radiation and scattering characteristics of the GPS antenna.Based on geometric optics-ray tracing method the transmission coefficient of GPS flat radome is analyzed,and based on Ansoft HFSS to simulation the GPS L1 microstrip circular patch antenna with radome is simulated,to get good performance GPS L1 band radome structure. |
