摘　　要：介绍串联支路与并联支路的等效阻抗互换方法,并基于阻抗等效法,对天线调谐器的匹配网络进行计算、仿真。基于Matlab平台,首先分析Γ型匹配网络中元件取值对天线调谐器可调谐区域的影响;其次,在Γ型匹配网络的基础上增加粗调电容,构成可调谐区域更大的Π型调谐网络,并计算Π型网络的可调谐区域,分析粗调电容对可调谐区域的影响;最后,设计调谐网络对某短波天线进行匹配仿真,提出了匹配网络的优化方法,为天线调谐器匹配网络设计提供参考。The equivalent impedance exchange method of serial and parallel branches is described, and based on the impedance equivalent method, the matching network of antenna tuner is calculated and simulated. Based on the Matlab platform, firstly the influence of the component value on the tuning region of the antenna tuner in Γ-section matching network is analyzed. Secondly, on the basis of Γ-section matching network, the Π-section tuning network with larger tunable region is generated in increasing the coarse tuning capacitor, and in addition, the tunable region of Π-section network calculated, and the influence of coarse tuning capacitor on the tunable region also analyzed. Finally, a tuned network is designed to match a short-wave antenna, and the optimization method of the matching network is proposed, thus providing a reference for design of antenna tuner matching network.
