HYBRID MAGNETIC SHIELDING SHEET FOR WIRELESS CHARGING AND NFC AND ANTENNA DEVICE FOR WIRELESS CHARGING AND NFC USING SAME

摘要

The present invention relates to a hybrid magnetic shielding sheet for a wireless charging and NFC and an antenna device for the wireless charging and NFC, capable of absorbing an electromagnetic wave required for performing an additional function and blocking the influence of a magnetic field generated in the implementation of the additional function of the wireless charging and NFC with a non-contact (wireless) method on a portable terminal device by combining a first magnetic sheet of high permeability and a second magnetic sheet of low permeability. The hybrid magnetic shielding sheet for the wireless charging and NFC according to the present invention includes the first magnetic sheet of the first permeability and the second magnetic sheet which is used for NFC, is stacked on one side of the first magnetic sheet and has the second permeability which is lower than the first permeability of the first magnetic sheet.;COPYRIGHT KIPO 2015
