Abstract: A wireless communication antenna comprises a magnetic body and coil portions. The coil portions have a solenoid shape formed around the magnetic body defining a core. The coil portions are spaced apart from each other and connected to each other in series. Magnetic fields radiated by the coil portions overlap each other and each of the coil portions comprises: a first wiring portion disposed on a first surface of the magnetic body; a second wiring portion disposed on a second surface of the magnetic body; and conductive vias interconnecting the first wiring portion and the second wiring portion.

Abstract: 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.
