Abstract
Abstract A high-gain monolithic antenna with high freedom of design has a signal circuit and a stripline dipole antenna which are provided on a substrate. A dielectric film and a conductor cover covering the dielectric film are provided on the upper surface of the substrate, in addition to a hole extending vertically downward to the underside of the substrate, a conductor wall being provided on the surface thereof. Furthermore, a metallic film is evaporated so as to contact both a metallic cover and a conductor wall. A first grounding conductor and a dielectric are provided on the lower surface of the substrate, and a second grounding conductor is provided on the upper surface of the substrate. A horn, which is tapered into the dielectric and the first grounding conductor thereby forming the shape of a quadrangular pyramid, is provided so as to overlap a hole etched into the substrate. Microwaves or milliwaves are radiated to/from the horn to/from the underside of the substrate.
