Abstract
A plane patch antenna has a dielectric substrate formed by calcining ceramic powder press-molded in a desired shape. On one surface of the dielectric substrate, a concave groove is continuously formed along the inside of its outer edge, and on an entire surface within a region partitioned by this concave groove, a patch electrode is thick-film printed.
Claims22
