Abstract
An antenna device includes a coil antenna including a coil conductor wound around a coil opening, and a planar conductor including a surface facing a portion of the coil opening and a portion of an area including the coil conductor. A minimum separation distance between the coil opening and the planar conductor in a direction perpendicular or substantially perpendicular to the planar conductor is larger than a minimum separation distance between the coil conductor and the planar conductor in the same direction. The planar conductor includes a first region that overlaps the coil opening and a third region that overlaps an outer edge of the coil conductor in plan view of the coil opening, and the first region includes a recessed portion that is recessed in a direction away from the coil conductor.
