    摘要： Provided are a large area type complex magnetic field shielding sheet and a wireless power transfer module including the same. A large area type complex magnetic field shielding sheet wherein at least one of an overall width, an overall length, and a diameter is 100 mm or more may include a main shielding layer arranged so that a plurality of ferrite block bodies each having a predetermined area are adjacent to each other, and an auxiliary shielding layer formed of at least one magnetic sheet having a predetermined area and laminated on the main shielding layer through an adhesive layer, wherein a boundary region between two ferrite block bodies disposed to be adjacent each other is disposed to be located in an inner region of the magnetic sheet and thus a magnetic field which leaks into a gap between the two ferrite block bodies is blocked by the magnetic sheet.

    摘要： A magnetic field shielding sheet and a wireless power transfer module that includes the same are provided. The magnetic field shielding sheet, according to an exemplary embodiment of the present invention, which is applied to a combo-type antenna unit that includes at least two antennas using different frequency bands of magnetic fields, comprises: a first sheet layer that includes a metal component that shields a first frequency band of a magnetic field and concentrates the magnetic field in a designated direction; a second sheet layer that shields a second frequency band of a magnetic field and concentrates the magnetic field in a designated direction; and a micro-piece separation and oxidation preventing member provided on a side surface of the first sheet layer in order to prevent a micro-piece from being separated from the side surface of the first sheet or to prevent the side surface from being oxidized. According to the present invention, by virtue of the micro-piece separation and oxidation preventing member provided on the side surface of the first sheet layer, it is possible to prevent the side surface from being oxidized and to prevent short-circuiting due to particles.

    摘要： The wireless power receiving module is disclosed. According to one embodiment of the present invention, the wireless power receiving module, to interact with a wireless power transmitting module including at least one wireless power transmitting antenna and a permanent magnet, includes an antenna unit including the wireless power receiving antenna formed of a hollow portion having a predetermined area at a central portion of a pattern portion and a shielding unit disposed on one surface of the antenna unit so as to shield a magnetic field. The shortest length between the inner sides of a coil pattern portion facing each other is the same as or larger than a diameter of the permanent magnet.
