Abstract

This disclosure provides a horizontal radiation antenna. The antenna includes a back-surface-side grounded conductor plate on a back surface of a substrate, a radiation element to which a coplanar line is connected on the front surface of the substrate, and a passive element closer to an end portion side of the substrate than the radiation element. A front-surface-side grounded conductor plate is provided at a substantially same height as the radiation element with respect to a thickness direction of the substrate, and a conductive wall surface capable of reflecting a high-frequency signal radiated from the radiation element is provided between the front-surface-side grounded conductor plate and the back-surface-side grounded conductor plate.
