摘　　要：设计了一个五-五单元微带贴片天线,中心层叠天线单元结合矩形贴片表面电流分布原理,由独立馈电实现工作。分析了天线的驻波比、轴比、增益、天线单元间的隔离度,以及天线两个工作频段之间的隔离。实现了BD(B3)("北斗"导航系统B3频段)和GNSS(全球导航卫星系统)两个导航定位频率的组合。不同频段天线单元复合布局,减小了天线的总体尺寸,能够应用于小型多功能接收机中。A five - five elements microstrip patch antenna is proposed in this paper. The centrally - stacked an- tenna elements are implemented by independent feeding, which is based on the surface current distribution of rectangular patch. The VSWR,AR and Gain of the antenna are analysed, isolation between the antenna elements and isolation between the two frequency bands are discussed. BD（B3） （Beidou system B3 band） and GNSS （Global Navigation Satellite System） hands are achieved simultaneously. By composite layout, the antenna is small in size and can be used in muhifunctional receivers.
