Abstract
A slot array antenna includes: an electrically conductive member having an electrically conductive surface and slots therein, the slots being arrayed in a first direction which extends along the conductive surface; a waveguide member having an electrically conductive waveguide face which opposes the slots and extends along the first direction; and an artificial magnetic conductor extending on both sides of the waveguide member. At least one of the conductive member and the waveguide member includes dents on the conductive surface and/or the waveguide face, the dents each serving to broaden a spacing between the conductive surface and the waveguide face relative to any adjacent site. The dents include a first, second, and third dents which are adjacent to one another and consecutively follow along the first direction. A distance between centers of the first and second dents is different from a distance between centers of the second and third dents.
