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.
