Abstract
A slot antenna device includes: a first electrically conductive member having a first electrically conductive surface and a second electrically conductive surface; a second electrically conductive member having a third electrically conductive surface that opposes the second electrically conductive surface; a waveguide member on the second electrically conductive surface; and an artificial magnetic conductor extending on both sides of the waveguide member. The first electrically conductive member has a slot. The waveguide member an electrically-conductive waveguide that opposes the third electrically conductive surface. The waveguide member includes a first ridge and a second ridge. One end of the first ridge and one end of the second ridge are opposed to each other. As viewed from a direction perpendicular to the waveguide face, the slot is located between the one end of the first ridge and the one end of the second ridge.
