Abstract: Disclosed herein is an antenna device that includes a first coil wound in a plurality of turns, and a second coil disposed outside the first coil as viewed in a coil axis direction of the first coil. The first coil is configured such that a first interval between turns in a first direction is larger than a second interval between turns in a second direction perpendicular to the first direction. An inter-coil distance between an outer edge of the first coil and an inner edge of the second coil is larger than the second interval as viewed in the coil axis direction.

Abstract: Disclosed herein is an antenna device that includes a coil pattern having first to third winding parts each having a plurality of turns. The first winding part has an outer peripheral end being opened and an inner peripheral end connected to an outer peripheral end of the second winding part. The second winding part has an inner peripheral end connected to an outer peripheral end of the third winding part. The third winding part has an inner peripheral end being opened. Each turn of the second winding part has a first partial winding part wound concentrically with the third winding part and a second partial winding part protruding radially outward from the first partial winding part and wound about a center axis positioned between the first partial winding part and the first winding part.

Abstract: Disclosed herein is a coil component that includes a first coil, and a second coil disposed so as to surround the first coil. The first coil includes a first section extending in a first direction, a second section extending in a second direction orthogonal to the first direction, and a third section positioned between the first and second sections. Gaps between the first, second, and third sections of the first coil and the second coil as viewed in a coil axis direction have a first width, a second width, and a third width, respectively. The second width is larger than the first width and smaller than the third width.

Abstract: Disclosed herein is an antenna device that includes: a metal plate having a first slit extending in a long side direction thereof and a second slit extending in a short side direction thereof; a first coil disposed so as to overlap with the metal plate in a plan view and circling along an outer edge of the metal plate; and a second coil electrically connected to the first coil, disposed so as to be surrounded by the first coil, and disposed so as to overlap with the first slit. The first slit has a first end that is open to divide the outer edge and a second end terminating without reaching the outer edge. The second slit has a third end that is open to divide the outer edge and a fourth end terminating without reaching the outer edge.

Abstract: Disclosed herein is an antenna module sheet that includes a first coil pattern including first to third turns. The first turn is positioned in an opening of the second turn, and the second turn is positioned in an opening of the third turn. Each of the first and second turns has an opening width larger in a first direction than in a second direction. The first distance between the first and second turns in the second direction is smaller than the second distance between the second and third turns in the second direction. The third distance between the first and second turns in the first direction is smaller than the first distance. The fourth distance between the second and third turns in the first direction is smaller than the second distance. The third turn has an opening width larger in the second direction than in the first direction.

Abstract: Disclosed herein is an antenna module that includes a substrate, a coil pattern formed on the first surface of the substrate, and a magnetic member covering the second surface of the substrate and having a through hole formed therein. The coil pattern has first and second coil sections. The second coil section is disposed in the opening of the first coil section. The inner peripheral end of the first coil section is connected to the outer peripheral end of the second coil section. The second coil section has a first extending section extending along the first coil section and a second extending section protruding from the first extending section toward the through hole in a plan view and wound in an opposite direction to a winding direction of the first extending section in a state overlapping the through hole.

Abstract: Disclosed herein is an antenna device that includes a first coil pattern having at least first, second, and third turns. As viewed in a coil axis direction, each of the first, second, and third turns has an opening with a width larger in a first direction than in a second direction orthogonal to the first direction. The width of the opening of the second turn in the second direction is larger than a width of the opening of the first turn in the second direction. The width of the opening of the third turn in the second direction is larger than the width of the opening of the second turn in the second direction and smaller than a width of the opening of the first turn in the first direction.
