发明名称 SOFT MAGNETIC SHEET FOR ANTENNA OF RECEIVING PART IN WIRELESS POWER SUPPLY SYSTEM
摘要 <p>According to an embodiment of the present invention, the present invention relates to a soft magnetic sheet for an antenna of a power receiving unit in a wireless power supply system where two or more layers of soft magnetic metal ribbons are stacked. The present invention has an insulation layer between the soft magnetic ribbon layers, and a magnetic shield is processed on a side surface of the soft magnetic sheet to form a closed magnetic circuit to minimize a loss of magnetic flux in a thickness direction of the soft magnetic sheet to improve a power transmission effect. Moreover, microcracks and a slit are formed on the soft magnetic ribbon in a wireless power supply system in order to increase a specific resistance to increase a frequency until a near field communications band, and efficiently use permeability in accordance with the direction of the magnetic flux as the soft magnetic ribbons are alternately stacked in order to increase power transmission efficiency.</p>
