中文摘要: 为了提升天线线圈在空间中产生的磁场强度，提出一种双驱动端口的双层天线方案.首先，从理论出发介绍了设计双层天线时应该考虑的各个参数；其次，改变双层天线的参数，通过三维电磁仿真软件Ansoft HFSS进行建模仿真，探究两线圈的匝数、间距、半径以及相对位置对双层天线的影响；最后，对仿真结果进行分析，找出了最优的双层天线设计方案，对实际设计的中高频RFID读写器天线具有一定的参考价值.

Abstract:In order to enhance the magnetic field strength of antenna coil in space,this paper proposes a method of double-layer antenna with two drive ports.First of all,this paper introduces each parameter which should be considered in the view of theory.Secondly,we change the parameters of the double-layer antenna,model and simulate it with the 3D electromagnetic simulation software Ansoft HFSS.Then,the influence of the coil number,the coil spacing,radius and the relative position of two coils on the double-layer antenna is researched.Finally,the simulate results show that the optimal design of double-layer antenna is found out and it is meaningful to the actual design of the antenna in medium-high frequency RFID reader systems.
