Abstract: An antenna device according to the present disclosure includes two wiring layers and an antenna layer. One of the two wiring layers is divided in the x-direction by a first slit extending in the y-direction, and the antenna layer is divided in the x-direction into first and second antenna areas by a second slit extending in the y-direction. The first and second slits overlap each other in the z-direction. One of the first and second slits is larger in width than the other one thereof. The antenna layer includes an antenna conductor formed in the first antenna area and another antenna conductor formed in the second antenna area.
