双频电子标签低频接收天线设计

内容简介：本文在低频磁通信与磁感应原理的基础上，设计了一种应用于双频电子标签低频部分的接收天线。通过对小型化低频磁性天线的研究，设计出了磁芯及线圈，并进一步制作了实验用天线。经测试表明，在电子标签的125KHz工作频段，该天线距发射天线5m处能够产生3~5mv的感应电压，从而能够接收到发射信号，满足实际应用要求。

Abstract：Basing on the theory of lowfrequency magnetic communications and magnetic induction, a low frequency receiver antenna which applied in dual-frequency electronic tags was designed. By studying the miniaturization of low-frequency magnetic antenna, the core and coil were designed, and furtherfabricated an antenna for the experimental. The tests show that the antenna can generate 3~5mv induced voltage at the distance of 5 meters away from the transmitting antenna whenworking at 125KHz. The antenna meet the requirements of practical application.
