Antenna module and radio communication device

摘要

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.

1. An antenna module comprising:
a coil conductor wound in a coil configuration; wherein the coil conductor includes a first coil conductor and a second coil conductor; 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; 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; and the first coil conductor and the second coil conductor are asymmetric to each other with respect to the magnetic layer.
