Abstract
A soft magnetic layer for a receiving antenna of a wireless power receiving apparatus includes a first soft magnetic member containing a Mn—Zn ferrite material, and a second soft magnetic member containing a Ni—Zn ferrite material. Accordingly, electromagnetic energy collecting performance of the receiving antenna of the wireless power receiving apparatus is improved, and thereby power transmission efficiency is maximized.
