摘　　要：首先介绍射频识别系统应用中模拟应答器测试线圈、阅读器天线的设计方法,该方法通过测量测试线圈电压的变化来反映阅读器的磁场强度变化的作用效果,然后对阅读器天线半径和作用距离作了定性分析。Firstly a method of designing the simulated transponder-testcoil and reader-antenna in the RFID system is presented. The method reflects the effect of the intensity change of the magnetic field of the reader by measuring the voltage change of the transponder- testcoil. Then, the relation of the reader-antenna＇sradius and its influenced distance are analysed qualitatively.
