ABSTRACT:
A metal plate patch antenna10includes a ground conductor composed of a metal plate, a dielectric substrate placed on and fixed to the ground conductor, a radiating conductor plate composed of a metal plate arranged above the dielectric substrate with a predetermined gap therefrom, leg pieces formed by cutting and raising four places near the outer circumferential portion of the radiating conductor plate toward the dielectric substrate, and a feeding metal piece extending from a feeding point of the radiating conductor plate. Soldering lands are arranged at four corners of the top surface of the dielectric substrate so that lower ends of the leg pieces are respectively soldered to the soldering lands.
