Abstract
A slot antenna device includes a first electrical conductor including first and second electrically conductive surfaces, a second electrical conductor including a third electrically conductive surface that opposes the second electrically conductive surface, a waveguide body on the second electrically conductive surface, and an artificial magnetic conductor extending on both sides of the waveguide body. The first electrical conductor includes a slot. The waveguide body includes a waveguide surface that opposes the third electrically conductive surface. The third electrically conductive surface, the waveguide surface, and the artificial magnetic conductor define a waveguide. The waveguide body includes a first ridge and a second ridge. As viewed from a direction perpendicular or substantially perpendicular to the waveguide surface, the slot is located between the one end of the first ridge and the one end of the second ridge.
