Title:
MAGNETIC FILM HAVING WIRELESS CHARGING RADIATOR FUNCTION, METHOD OF MANUFACTURING THE SAME, AND WIRELESS CHARGING DEVICE USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2013/165167
Kind Code:
A1
Abstract:
Since the magnetic film (10) of the present invention has a much thinner thickness compared to a corresponding conventional magnetic layer and radiator coil material assembly and has no adhesive layer or air layer between the magnetic layer and the radiator, permeability required at the time of charging can be improved, a loss rate can be reduced and high charging efficiency can be obtained, Furthermore, since a band width and a gain rate can be improved, the magnetic film can be very usefully applied to wireless charging products which pursue slimming in design.
