Abstract: A system and method of adaptively tuning an antenna of a wireless device including detecting a reflected electrical signal from the antenna during transmission of a wireless signal, converting the reflected electrical signal into at least one parameter indicative of its strength, and adjusting, based on the at least one parameter, a tune value to adjust a matching network during the transmission of the wireless signal to reduce the strength of the reflected electrical signal. The reflected electrical signal may be converted to a corresponding power value, and the tune value may be repeatedly adjusted by an incremental amount or according to a binary search method or the like to reduce the power level of the reflected electrical signal. The reflected electrical signal may be demodulated into demodulated information used to determine an optimal transfer function of the matching network and the tune value may be adjusted accordingly.
