摘　　要：通过在贴片上开等长度的十字缝隙的方式,设计了一种小型化的GPS双频微带天线。仿真结果表明,天线长和宽较开缝前分别减小了28.9%和35.4%,且在1.227GHz和1.575GHz两个频段点处,回波损耗分别达到了-23.2dB和-15dB。天线辐射性能良好,结构简单易于实现。A miniaturized GPS dual-frequency microstrip antenna is designed by providing a cross-shaped slot of equal length on the patch. The simulation results show that the anten- na length and width are decreased by 28.9 % and 35.40/60 respectively than before, and the re- turn loss reaches -23.2 dB and -15 dB at 1. 227 GHz and 1. 575 GHz. Moreover, the antenna has well unitary radiation and simple configuration.
