Abstract
An antenna system and method utilize an evaluation branch circuit and an implementation branch circuit. These circuits are each connected to both a first antenna input and a second antenna input. An output of the evaluation branch circuit is in communication with a controller while an output of the implementation branch circuit is in communication with a receiver. Each branch circuit includes at least one signal conditioner to change an electrical characteristic of RF signals received from antennas via the antenna inputs. The evaluation branch circuit, controlled by the controller, changes the electrical characteristics of the RF signals in a variety of different ways to discover an optimized evaluation RF signal. Once the optimized evaluation RF signal is determined, the implementation branch circuit is controlled, by the controller, to produce an optimized implementation RF signal in accordance with that discovered by the evaluation branch circuit.
