Abstract: A pad assembly for power reception of an electric vehicle includes a receiving pad configured to support a receiving coil connected to an external component, and a magnetic complex layer disposed above or below the receiving coil. An increment in inductance per unit density of the magnetic complex layer disposed above or below the receiving coil is 25%·cm3/g or more compared to an increment in inductance per unit density of the magnetic complex layer alone not disposed above or below the receiving coil.

Abstract: An antenna device in which a conductive foil or an antenna pattern directly formed on the magnetic sheet without an insulating substrate such as polyimide, has a reduced thickness and may be prepared simple process. Also, with respect to the antenna device, flexibility may be improved by using a polymer-type magnetic sheet, and, since magnetic properties are excellent, the antenna device may be used for multiple applications such as NFC, WPC, and MST.

Abstract: A magnetic sheet having improved acid/base-resistant properties, corrosion-resistance, and an excellent magnetic property at NFC, WPC, and MST frequencies, has little changes in weight and thickness even if the environment changes, for example, even after an etching treatment for patterning, or a reflow or soldering process which is performed for its application to a product.
