In a patch antenna including a dielectric having a top surface, a bottom surface, and a side surface, a radiation element formed on the top surface of the dielectric, and a ground conductor formed on the bottom surface of the dielectric, a ring-shaped non-feeding element is formed on the side surface of the dielectric. The non-feeding element preferably may be formed on the side surface of the dielectric in the vicinity of the top surface of the dielectric. In addition, the non-feeding element may be formed by pasting a copper tape or by thick film printing.
