Kind Code:
A1
Abstract:
According to various embodiments of the present disclosure, a power receiving device comprises: a housing comprising 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 and second surface; a coil antenna wound in a circular shape and disposed in an inner space of the housing so as to wirelessly receive power from a power transmitting device; a shielding sheet disposed above the coil antenna; and a first magnet and a second magnet disposed adjacent to the outermost coil of the coil antenna and spaced apart from the outermost coil. The first magnet may be disposed such that a part of magnetic force induced by the first magnet is formed in the first direction. The second magnet may be coupled to the first magnet in a third direction defined from the center of the coil antenna to the outside, and may be disposed such that a part of magnetic force induced by the second magnet is formed in the third direction.
