Abstract
An antenna device includes a radiating conductor plate made of a metal sheet having an outer appearance of a substantially square shape and arranged on a ground conductor with a predetermined distance therefrom; a feed pin extending from a feeding point of the radiating conductor plate and connected to a feeding circuit; and leg pieces extending from four points of an outer circumferential edge of the radiating conductor plate to support the radiating conductor plate in a state insulated from the ground conductor. The four leg pieces are offset by predetermined distances from midpoints of respective sides of the radiating conductor plate, thereby forming degenerative separating elements. As a result, the antenna device 10 can be operated as a circularly polarized wave antenna.
