摘要
设计了一种用于通信、导航、定位等领域的小型化GPS微带天线。采用了椭圆贴片辐射单元及接地板开槽技术,通过接地板开槽引入微扰,在实现圆极化的同时,减小了天线尺寸,实现了小型化:比同频率下传统圆极化微带天线尺寸减小32%,比同结构矩形贴片增益高35%,且频带宽度和轴比带宽都有所提高。
A compact GPS microstrip antenna is designed, which can be applied in communications, navigation ,positioning and other areas. With the radiation element of the oval patch and the slotted ground plane adopted,the ground plane embedded slots can excite circular polarised（CP） radiation, at the same time, it has achieved compact size. Compared with the traditional CP microstrip antenna,the patch size is reduced up to around 32% at the same frequency;while its gain is 35% higher than that of the similar structure of the rectangular patch, and the bandwidth and axial ratio bandwidth are improved.
