Abstract
In various embodiments, systems and methods for automatically tuning an antenna to a desired frequency utilize a tuning detection element that sends or receives a signal in accordance with one mode of the antenna and that is separated from the antenna by a gap and outside of a signal path of the antenna. In various system implementations, a processor communicates with the tuning detection element and antenna and monitors the amplitude of a signal transmitted to or from the tuning detection element. A resonant frequency of the antenna may be tuned to the desired frequency by a tuning element.
