20130113668 | Systems for Focusing and Defocusing an Antenna - Embodiments provide systems for focusing and defocusing an antenna. The antenna may be a printed antenna, such as a patch antenna, for example, and may include a single element antenna or a multi-element antenna array. Embodiments include a focusing/defocusing structure, including a plurality of metal rings that form a multi-layer structure, peripheral to the antenna. In an embodiment, the focusing structure is designed to have a horn configuration, with the metal rings having progressively increasing respective widths in the direction away from the antenna.
