摘　　要：为了使13.56 MHz射频识别天线适合于智能钥匙柜应用中,对13.56 MHz PCB天线的工作原理、作用机理进行了简单的介绍,然后对应用于智能钥匙柜的13.56 MHz平面螺旋电感天线进行了理论分析计算、CST三维电磁场仿真、匹配电路仿真,最后通过矢量网络分析仪对设计的13.56 MHz射频天线进行测试,测试结果表明设计的13.56 MHz天线达到了设计的要求,能够用于智能钥匙柜识别天线中。In order to design 13.56 MHz RFID antenna suitable for smart key cabinet applications, the working principle and working mechanism of 13.56 MHz PCB antenna is briefly introduced, and then the 13.56 MHz planar spiral inductor antenna used in the smart key cabinet and a software for 3 D electromagnetic field analysis(CST)and matching circuit simulation is theoretically analyzed and calculated. Finally, the designed 13.56 MHz RF antenna is tested by a vector network analyzer. The test results show that the designed 13.56 MHz antenna meets the design requirements and can be used in smart key cabinet identification antennas.
