Abstract: An example electronic device includes a battery, a coil antenna that transmits power of the battery, a shield disposed on a lower surface of the coil antenna, and a plurality of magnet modules formed to surround at least a portion of a side surface of the coil antenna. Each of the plurality of magnet modules includes an inner part that faces toward the side surface of the coil antenna, an outer part that faces toward an opposite side to the coil antenna, and a non-magnetized area disposed between the inner part and the outer part. The inner part includes a first inner area and a second inner area over the first inner area, and the outer part includes a first outer area and a second outer area over the first outer area. The first inner area and the second outer area are magnetized with a first polarity, and the second inner area and the first outer area are magnetized with a second polarity opposite to the first polarity.

Abstract: A power reception device includes: a housing including a first surface facing in a first direction, a second surface facing in a second direction opposite to the first direction, and a side surface surrounding a space between the first surface and the second surface; a coil antenna wound in a circle; a shielding sheet disposed over the coil antenna; and a first magnet and a second magnet adjacent to an outermost coil of the coil antenna and disposed to be spaced apart from the outermost coil. The first magnet is disposed so that a portion of magnetism induced by the first magnet is formed in the first direction. The second magnet is disposed so that a portion of the magnetism induced by the second magnet is formed in a third direction that is an outside direction from a center of the coil antenna.
