Abstract
A wireless power transmission module is provided. According to an exemplary embodiment of the present disclosure, a wireless power transmission module includes an antenna unit, a magnetic field shielding sheet, and a planar heat radiating plate. The antenna unit includes at least one wireless power transfer antenna. The magnetic field shielding sheet shields a magnetic field generated by the antenna unit to suppress external leakage of the magnetic field and concentrate the magnetic field in a desired direction. The planar heat radiating plate which is disposed on one surface of the magnetic field shielding sheet to release heat generated by the antenna unit. The wireless power transmission module is equipped or embedded in a vehicle to be used to charge a main battery of a portable terminal.
