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