Abstract
An antenna device includes a first coil antenna and a second coil antenna. The first coil antenna includes a coil conductor having a rectangular or substantially rectangular spiral shape and located on a non-magnetic insulating base member. The second coil antenna includes two coil conductors located on a non-magnetic insulating base member. The two coil conductors are disposed and wound such that loops of a magnetic field that is generated by applying a current to the two coil conductors are perpendicular or substantially perpendicular to a coil axis of the coil conductors.
