A wireless power charging device includes a coil configured to transmit or receive a wireless power signal; an electromagnetic wave shielding sheet disposed proximate the coil; and, a heat radiation layer disposed on the electromagnetic wave shielding sheet.

Wireless power charging device

A sheet is provided to shield against electromagnetic waves. The sheet includes a magnetic layer, and a heat radiation coating layer coating at least a portion of a surface of the magnetic layer.

Sheet for shielding against electromagnetic waves and wireless power charging device

A device for transmitting data includes a transmitting coil configured to receive and transmit the data signal and to generate a magnetic field, and a magnetic material provided on one surface of the transmitting coil. A ratio of a residual magnetic flux density and a saturation magnetic flux density of the magnetic material is greater in a direction that the material is magnetized than in a direction the material is not magnetized.

Magnetic material and device for transmitting data using the same

A magnetic field shielding sheet and a wireless power charging apparatus including the same are provided. A magnetic field shielding sheet includes a magnetic field shielding area including magnetic field shielding layers disposed on a surface of a coil part configured to provide a wireless power charging function to shield a magnetic field generated from the coil part and an adhesive layer bonding the magnetic field shielding layers to each other, and heat radiation fillers disposed within the adhesive layer.
