Abstract
An antenna devicehas a dielectric substrate, a patch antennaand electric power absorbing passive elementsformed on a surface of the dielectric substrate. Each electric power absorbing passive elementis formed between the patch antennaand an edge portion in a polarized wave direction of the dielectric substrate. The electric power absorbing passive elementsabsorb a part of electric power received by the patch antenna. This makes it possible to suppress a surface current flowing to the edge portions of the dielectric substrate on a conductive plate (a front-surface conductor plateor a back surface conductor plate) on the dielectric substrate.
