Abstract
A planar, controlled radiation pattern array antenna using spiral slot antenna arrays is disclosed. The CRPA antenna includes a nonconductive planar substrate with a plurality of transmission lines disposed on one surface. A conductive layer on the other surface of the substrate includes a plurality of slotted openings that form spiral slot array antennas such that each spiral slot array antenna opposed to a transmission line on the opposite side of the substrate.
