介绍了天线调谐器T形匹配网络的结构组成和元件配置;在给定VSWR门限值的条件下,定量分析了匹配网络中各元件的最小取值所必须满足的取值范围,得出了合理的估算值.对于决定网络匹配范围的各元件的最大取值,则依据天线输入阻抗的变化范围,给出了初步的估算值.通过对以上两类参数的估算,为天线调谐器调谐算法的设计和整备性能指标的实现提供了参考依据.

The structure form and component configuration of T?type matching network in antenna tuner are intro?duced. The value range satisfying the minimum value needed by each component are analyzed quantitatively according the ap?pointed critical value of voltage standing wave ratio(VSWR). The reasonable estimation value was got. As for the maximum values of all the components which determins the matching domain, the preliminary estimation value was obtained according the input impedance of antenna. Through the estimation of the two sorts of parameters, the reference basis is provided for the design of tuning algorithm and performance indexes of antenna tuner.
