Abstract
A slot array antenna includes: a first electrically conductive member having a first electrically conductive surface; a second electrically conductive member having a second electrically conductive surface opposed to the first electrically conductive surface; a waveguide member located between the first and second electrically conductive members; and an artificial magnetic conductor extending on both sides of the waveguide member in between the first and second electrically conductive members. The first or second electrically conductive member has a plurality of slots. The waveguide member includes an electrically-conductive waveguide face of a stripe shape opposed to the first electrically conductive surface. The plurality of slots include at least two slots that couple to the waveguide face. In between two positions respectively coupled to the two slots, the waveguide face includes at least one deflecting portion at which the direction that the waveguide face extends changes.
