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 12):
The wireless power transmission module operable in magnetic resonance method of  claim 1 , wherein a copper plate having a thickness of 30 \u03bcm is disposed as the conductor on one surface of the wireless power transmission module on a surface of the magnetic field shielding unit and a bifilar coil including two first radiators is disposed at predetermined distance from one surface of the wireless power transmission module on a side of the radiator unit, 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 wireless power transmission module having the second radiator as the radiator for wireless power transmission 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.)
