Abstract
An antenna device comprises an antenna board, wherein an antenna pattern is formed in or on a front surface of a dielectric layer, a ground layer is formed in or on a rear surface of the dielectric layer, and a feed pin is inserted into a thickness of the antenna board through the ground layer and the dielectric layer. The diameter of the antenna pattern is set to one half of the wavelength of an RF signal passed through the antenna pattern, and a length of one side of the dielectric plate is set shorter than the wavelength. A metallic plate is coupled to the ground layer with a plurality of metallic spacers interposed therebetween, whereby the metallic plate is electrically connected to the ground layer.
