Wireless power transmission/reception device
First Claim
1. A magnetic field control member, for focusing a magnetic field between a primary coil connected to a power source of a wireless power transfer system and forming a magnetic field and a secondary coil receiving power through the magnetic field, the member comprising:
- a substrate having one surface disposed between the primary coil and the secondary coil so as to face the primary coil or the secondary coil;
a pattern unit disposed over the substrate and comprising a plurality of thin films spaced apart from each other by a certain interval, wherein the plurality of thin films have a linear shape with the same length;
and a connection unit electrically connecting the plurality of thin films.

Abstract
The present description relates to a wireless power transmission/reception device. The present description provides a magnetic field controlling member for focusing a magnetic field between a primary coil, which is connected to a power source of a wireless power transmission system and forms a magnetic field, and a secondary coil which is for receiving power by means of the magnetic field. The magnetic field controlling member includes: a substrate, between the primary coil and secondary coil, of which one side faces the primary coil or secondary coil; a pattern unit which is placed on the substrate and has a plurality of thin films that are positioned at a predetermined distance away from each other; and a connecting unit which electrically connects the plurality of thin films.
