Abstract: An antenna device is provided with a planar coil antenna having a planar section provided along a first plane and a first folded section provided along a second plane crossing the first plane and a first metal layer. A first border line between the planar section and the first folded section crosses an inner diameter portion of the planar coil antenna. The first metal layer covers at least a part of the planar section of the planar coil antenna and at least a part of the inner diameter portion.

Abstract: An antenna device is provided with a substrate; an antenna coil formed into a loop-shaped or spiral-shaped on the substrate; a first metallic layer overlapping with a first part of the antenna coil in a planar view; and a second metallic layer overlapping with a second part of the antenna coil different from the first part. The first and second metallic layers are disposed on both sides of a center of an inner diameter portion of the antenna coil in a planar view, respectively. A slit formed between the first and second metallic layers overlaps with the inner diameter portion of the antenna coil in a planar view. At least one of the first and second metallic layers is formed on the substrate together with the antenna coil.
