Abstract:
1. A method for tuning an antenna to a desired signal frequency at which a given signal has a maximal response, comprising: detecting a first response of the antenna at a first frequency to which the antenna is tuned; detecting a second response of the antenna at the second frequency to which the antenna is tuned that is different from the first frequency; comparing the first response and the second response; changing the frequency to which the antenna is tuned based on the comparison of the first response and the second response; wherein the steps of detecting the first and second responses, comparing the first and second responses, and changing the frequency to which the antenna is tuned based on the comparison are performed iteratively so as to progressively move the frequency to which the antenna is tuned to the desired signal frequency; wherein changing the frequency to which the antenna is tuned based on the comparison of the first response and the second response comprises selecting a magnitude of a change in frequency of the antenna based on the comparison of the first response and the second response.
