Patent ID: 8847831

Claim:
An antenna module comprising: an antenna including: an insulation base member including first and second main surfaces which face each other; a first coil electrode arranged on the first main surface in a winding manner and including end portions; and a second coil electrode arranged on the second main surface, wound in a direction opposite to a winding direction of the first coil electrode when viewed in a direction from the second main surface to the first main surface, and including end portions; and an electromagnetic coupling module including a wireless communication IC and a power-supply coil connected to the wireless communication IC; wherein in a planar view, the electromagnetic coupling module is arranged on the first main surface of the insulation base member so that the electromagnetic coupling module overlaps only with an electrode included in a group of electrodes that are arranged in parallel or substantially in parallel and are defined by the first coil electrode; and the power-supply coil is electromagnetically coupled with the first coil electrode.
