摘要
根据NXP公司给出的13.56MHz读写器天线匹配网络的拓扑,借助史密斯圆图,给出此网络参数的详细设计过程。较之与NXP公司提出的理论公式计算方法,史密斯圆图法更加快速、简练、直观、易懂,实现了13.56M高频阅读器天线负载阻抗与源阻抗的共轭匹配。
According to the 13.56 MHz reader antenna matching network topology given by NXP companies, the paper give detailed design process of this network parameters with the aid of Smith chart. Compared with the theoretical formula calculation method which NXP company put forward, Smith chart method is more rapid,simple,intuitive,easy to understand. And it is better to achieve the 13.56M high frequency reader load impedance and source impedance conjugate matching.
