Abstract
A composite ferrite magnetic field shielding sheet is divided into at least two regions. The at least two regions have different properties by adjusting raw ferrite particles suitable for forming at least two functional coil patterns from among wireless power charging (WPC), near field wireless communication (NFC), and magnetic security transmission (MST) coil patterns.
