摘要
A magnetic resonance wireless power transfer module is provided. A magnetic resonance wireless power transfer module including a wireless power transfer radiator disposed adjacent to a conductor, wherein the magnetic resonance wireless power transfer module according to an embodiment of the present invention includes the wireless power transfer radiation. A radiator unit including a body; and a Fe-based alloy fragment disposed on one surface of the radiator unit and crushed to improve flexibility of the shielding unit and reduce eddy current generation, and one of the fragments A magnetic field shielding layer including a dielectric material that fills at least a part of a separation space formed between adjacent pieces of the portion to reduce generation of eddy current, and blocks transmission and reception interference of the radiator by the conductor; The magnetic field shielding unit for improving the characteristics of the radiator is implemented. According to this, when transmitting and receiving a wireless power signal by the magnetic resonance method, the power signal by a conductor that can be arranged adjacent to the surroundings, blocking the influence of the magnetic field on components such as portable terminal devices and users using the same The transmission / reception interference can be minimized or cut off, and the characteristics of the radiator can be remarkably improved, so that the wireless power transfer efficiency of the magnetic resonance method can be remarkably improved.
