Abstract
An antenna array system includes a launcher comprising an antenna configured to establish and steer a wavefront, and an array of Yagi-Uda director trains coupled to the launcher and located in the path of the wavefront. The array of Yagi-Uda director trains is configured to influence a beamwidth of the launcher. A method for beam steering includes launching a wavefront generated by an antenna through an array of director elements, and steering the wavefront. The array of director elements focuses the wavefront and influences gain of the antenna over plural steering angles.
