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.
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.
