ABSTRACT:
Systems and methods for a wireless communication device having a switched multi-beam antenna and methods for manufacturing the same are described. One system and method includes a plurality of antenna of elements. Groups of the antenna elements cooperate to form active one or more antenna elements while other groups of the antenna elements cooperate to form a reflector for the active antenna elements. This creates a directed transmission or direction of positive gain for the antenna system. The same group of antenna elements can be switched so that other antenna elements cooperate to form the active element while another group forms a reflector for the active elements thereby providing a different direction of positive gain. The system can be used for various wireless communication protocols and at various frequency ranges.
