First Claim
1. A wireless power reception device comprising:
- a planar resonator configured to be coupled with external magnetic fields and generate an induced current;
a first ferrite member mounted on a first side of the planar resonator and positioned in a lower portion of the planar resonator; and
a second ferrite member mounted on a second side of the planar resonator opposite to the first side and positioned in an upper portion of the planar resonator,wherein the external magnetic fields pass through an aperture of the planar resonator substantially from one of the first side of the lower portion of the planar resonator and the second side of the upper portion of the planar resonator to the other of the first side of the lower portion of the planar resonator and the second side of the upper portion of the planar resonator.

Abstract
Apparatuses, systems, and methods of wireless power transmission/reception are described. In one wireless power transmission/reception device, a planar resonator capable of generating magnetic fields has one or more ferrite members mounted thereon such that the magnetic fields generated by the planar resonator have an overall direction substantially tilted or parallel to its opening/face, i.e., to the plane of the planar resonator. In a wireless power reception device, the planar resonator generates magnetic fields and an induced current when being resonated by external magnetic fields; in a wireless power transmission device, the planar resonator generates magnetic fields when being supplied with power.
