Abstract
A conformal patch antenna comprises an aperture layer having an at least partially metallized surface that may have at least one aperture slot therein, and a feed-network layer positioned adjacent to the aperture layer and having a feed-network circuitry metallized thereon. The aperture layer and feed-network layer may be comprised of a low permittivity dielectric material. The dielectric material of the aperture and the feed-network layers may be formed in a predetermined shape by a molding process prior to metallization. The feed network may be located within a recessed area of the feed-network layer dielectric, and may include at least one signal probe molded in the dielectric material and having metallization thereon to align with holes in aperture layer. The signal probes may couple signals from the aperture to the feed-network circuitry.
