Abstract:
A wireless power transmission module operable in magnetic resonance method including a radiator unit for wireless power transmission, and a magnetic field shielding unit, disposed on a side of the radiator unit, for preventing disturbance of transmission and reception of the radiator due to the conductor and improving radiator characteristics, by providing a magnetic field shielding layer which includes shredded Fe-based alloy fragments and a dielectric filling at least a part of gaps between shredded Fe-based alloy fragments and some adjacent ones of the fragments to reduce eddy currents, to improve flexibility of and reduce eddy currents in the magnetic field shielding unit. When a wireless power signal is transmitted and received in a magnetic resonance method, the influence of a magnetic field on components of s a mobile terminal or a user can be blocked. Interference with the transmission/reception of the power signal due to the conductor can be minimized or prevented. The radiator characteristics and wireless power transmission efficiency can be remarkably improved.

Claim (Index 14):
The magnetic field shielding unit for wireless power transmission operable in magnetic resonance of  claim 13 , wherein a second radiator is disposed on one surface of the magnetic field shielding unit, a copper plate having a thickness of 30 \u03bcm is disposed on the other surface of the magnetic field shielding unit, and a bifilar coil including two first radiators is disposed at predetermined distance from the second radiator in parallel, and wherein when a wireless power signal is transmitted by applying an input voltage of 6 V of a driving frequency of 750 kHz to the bifilar coil, a maximum receiving distance at which the second radiator can receive the wireless power signal is 58 mm or more.\n (*The first radiator and the second radiator formed by winding a strand of copper having a diameter of 500 \u03bcm 5 turns have an outer diameter of 50.5 mm\u00d750.5 mm, an inner diameter of 50 mm\u00d750 mm, a circular shape, and have an inductance (Ls) of 3.1 to 3.15 \u03bcH and a specific resistance (Rs) of 350 to 400 m\u03a9 when measuring with an LCR meter under a condition of 750 kHz/1 V.)
