Abstract

A method for an antenna mismatch compensation may include determining an amplitude ratio by measuring a ratio of amplitudes of a reflected signal and an incident signal of an antenna tuning circuit coupled to an antenna. A time difference between the reflected signal and the incident signal may be measured. The time difference may be converted to a phase difference. A topology and one or more parameters of the antenna tuning circuit may be determined based on the amplitude ratio and the phase difference so that the antenna tuning circuit compensates for the antenna mismatch.
