摘要: The present invention is directed to multi-element antennas that include, for each adjacent pair of antenna elements, at least one switch arranged selectively connect thereby alter an dimension. Accordingly, a (61,62, 63) can be configured enhance its gain different operational frequencies while corresponding impedance matching network (44) the match (i.e., reduce reflected signal energy) between (20) and system (40) (e.g., transceiver system). thus effectively tuned across wide band. are with (36) command signals provided in response plurality frequency codes.
