US Patent 7696948 Configurable directional antenna

Systems and methods for a directional antenna and methods for manufacturing the same are described. One system and method includes a plurality of antenna elements. Groups of the antenna elements cooperate to form a directional antenna. In one configuration, a first element is configured as a driven element and a second element is configured as a delayed element. The elements are separated by a distance such that an RF signal radiated from the driven element constructively combines with a delayed RF signal radiated by the delay element. In another configuration, the second element can be configured as the driven element and the first element configured as the delayed element.
