Document Type and Number:
WIPO Patent Application WO/2017/082553
Kind Code:
A1
Abstract:
The present invention relates to a composite ferrite magnetic field shield sheet, a method for manufacturing the same, and an antenna module using the same. More particularly, the present invention relates to a technique regarding a composite ferrite magnetic field shield sheet which is divided into regions having at least two different properties by adjusting raw ferrite particles so as to be suitable for forming at least any two functional coil patterns from among wireless power charging (WPC), near field wireless communication (NFC), and magnetic security transmission (MST).
