摘要
针对非接触型IC卡对读写机具参数的影响，建立了相应的数学模型。通过数学模型进行仿真，化入设定的参数值求解，定量求出非接触型IC卡对读写机具参数的影响程度。为了实现IC卡和读写机具之间最佳能量传输，需要在源和负载之间加一匹配网络以达到阻抗匹配，最后推导并验证了读写机具射频匹配网络的计算公式。
According to the influence of non-contact IC card on parameters of read-write equipment, the corresponding mathematic models are established. By simulating with a set of parameters, the influence degree of the card on parameters of read-write equipment can be quantitatively calculated. In order to realize the best energy transmission between the IC card and the read-write equipment,a matching network is needed between the source and load to get the impedance matching. Finally the calculation formula of RF matching network of the read-write equipment is deduced and verified.
