天线调谐器反Г形阻抗匹配网络适配HF双极天线分析

Analysis on reversed-Г-section impedance matching network of antenna tuner in matching HF dipole antenna

介绍天线调谐器反Г形阻抗匹配网络的结构形式和匹配区域;分析反Г形网络各参数取不同值时对HF双极天线的适配性,给出参数变化随频率、VSWR门限变化时对HF双极天线输入阻抗的适配曲线,为设计天线调谐器阻抗匹配网络和决定天线调谐器适配天线类型提供参考.

The structure and matching range of reversed - Г - section impedance matching network of antenna tuner were introduced at first. Then the reversed - Г - section impedance matching network was analyzed in matching HF dipole antenna with different parameters, and the matching curve of inputting impedance of antenna can be got with different frequencies and threshold VSWR in various parameters. This analysis can be referenced in designing impedance matching network of antenna tuner and in deciding antenna type matched by antenna tuner.
