Abstract: An electronic device may include a memory; a processor; communication circuitry; and an antenna. The antenna may include an insulation sheet; an antenna pattern disposed in the insulation sheet and having a meander form; a first magnetic sheet layer disposed on a first surface of the insulation sheet; and a second magnetic sheet layer disposed on a second surface of the insulation sheet. Each of the first magnetic sheet layer and the second magnetic sheet layer may include a plurality of magnetic sheets disposed at specified intervals each having a first area. The plurality of magnetic sheets of the first magnetic sheet layer may be disposed to correspond to the first areas of the second magnetic sheet layer.
