Abstract: An antenna device includes a first conductor plane and a second conductor plane that face each other. The first conductor plane and the second conductor plane are electrically continuous through a first connection conductor, a second connection conductor, and a chip capacitor. A power feed coil is disposed between the first conductor plane and the second conductor plane. The power feed coil includes a magnetic core and a coil conductor. The coil conductor defines a pattern such that the coil conductor winds around the magnetic core. The power feed coil is disposed at a position closer to the first connection conductor and magnetically couples with the first connection conductor.

Abstract: An antenna module includes a first coil conductor, a second coil conductor and a magnetic layer. The first coil conductor and the second coil conductor are arranged with a magnetic layer interposed therebetween so that a coil aperture of the first coil conductor and a coil aperture of the second coil conductor are opposed to each other in alignment. An inner end portion of the first coil conductor and an inner end portion of the second coil conductor are electrically connected. The first coil conductor and the second coil conductor are connected to each other so that directions of magnetic fluxes generated in coil-wound axis directions of the first coil conductor and the second conductor are mutually opposite to each other. A magnetic flux φ entering a metal body in a perpendicular direction thereto flows in a lateral direction of the magnetic layer.
