摘要
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。
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.
