Abstract
A low profile receiving and/or transmitting antenna includes an array of lenses that focuses millimeter wave or other radiation onto a plurality of conventional patch antenna elements. The lenses and antenna elements are physically configured so that radiation at a tuning wavelength impinging on the antenna at a particular angle of incidence is collected by the lenses and focused onto the antenna elements in-phase. Two rotatable prisms may be disposed above the lenses to alter the angle of incidence of incoming or outgoing radiation to match the particular angle of incidence.
