摘　　要：在FR4基板上,通过在标准矩形微带天线贴片上切去部分而形成圆极化的工作方式,设计了一种单馈点圆极化微带天线。仿真实测结果表明,天线工作在1.590 GHz的GPS频段,工作频带上轴比性能良好,得到的天线各项性能参数,满足GPS接收机所需天线的性能要求。On FR4 substrate, a part of standard rectangular microstrip antenna patch is cut away, through which a circularly polarized way of working is formed. Then, a single-feed circularly polarized microstrip antenna is designed in this article. The simulation results show that the antenna has a good axial ratio performance when it operates at 1. 590 GHz for GPS and the performance parameters of the antenna obtained can meet the performances request of the antenna need for GPS receiver
