Abstract
A system and method are provided for regulating the electrical length of an antenna. The method comprises: communicating transmission line signals at a predetermined frequency between a transceiver and an antenna; sensing transmission line signals; and, modifying the antenna electrical length in response to sensing the transmission line signals. Sensing transmission line signals typically means sensing transmission line signal power levels. In some aspects, the antenna impedance is modified. Alternately, it can be stated that the transmission line signal strength is optimized between the transceiver and the antenna. More specifically, communicating transmission line signals at a predetermined frequency between a transceiver and an antenna includes accepting the transmission line signal from the transceiver at an antenna port. Then, sensing transmission line signals includes measuring the transmission line signal reflected from the antenna port.
