Patent ID: 8712355

Claim:
A communications device comprising: at least one radio transceiver; at least one antenna that has an input impedance which varies in response to changes in operating conditions of the communications device; an antenna tuner coupled between the at least one radio transceiver and the at least one antenna; a persistent memory which stores a plurality of pre-established trajectories of antenna tuning states and a corresponding plurality of pre-identified device operating conditions and communications modes; and an antenna tuner controller connected within a feedback configuration that provides the antenna tuner controller with detected signal levels and determines a current operating condition of the communications device, wherein at least one of said detected signal levels is utilized by the antenna tuner controller to generate antenna tuning states that the antenna tuner controller forwards to the antenna tuner to adjust the at least one detected signal level towards a given value, wherein the generated antenna tuning states represent a sequence of points along a selected, pre-established trajectory of tuning states that corresponds to a particular pre-identified operating condition that best matches the current operating condition.
