Abstract
Method and system for tuning a tunable antenna uses a comparison between a signal response at two different tuning frequencies to determine how or if the tuning needs to be further adjusted. With the approach, the method and system arrive at a frequency shift that is centered about the desired antenna frequency, which point there is no net change in the signal response. In a further aspect, a frequency to which a tuned antenna is tuned is shifted to verify whether the antenna is still in tune. Modifications to minimize disturbance of the output received signal that would otherwise be caused by the frequency shifting are contemplated.
