An antenna apparatus includes a first substrate, and a conductor pattern disposed on a surface of the first substrate and forming magnetic flux in a normal direction with respect to the surface of the first substrate. The antenna apparatus also includes a second substrate spaced apart from the first substrate, and a member disposed on the second substrate. The antenna apparatus further includes a coil wound around the member, and a current feeder configured to provide a first current to the conductor pattern and a second current to the coil.
