摘　　要：本文介绍了两种用于UHF频段RFID系统阅读器天线的设计方法,一种是具有圆极化特性的微带天线,另一种是方向图可预先设定的四单元微带天线阵,并给出了仿真与测试结果。This article mainly introduced two designing means which were used in UHF frequency RFID system reader antenna. One is a micro-antenna with the characteristic of circular-polarization. The other one is four-unit micro-antenna array whose direction picture could be set beforehand, meanwhile, the simulation and experimental result were provided.
