Abstract

A wireless power transmission apparatus is provided. The wireless power transmission apparatus includes a first coil including a first conductive wire area formed of an arrangement of conductive wires, and a first opening area surrounded by the first conductive wire area, a second coil including a second conductive wire area formed of an arrangement of conductive wires, and a second opening area surrounded by the second conductive wire area, a first overlapping area formed by overlapping a portion of the first conductive wire area with a portion of the second opening area, and a first shielding member disposed on at least a portion of the first overlapping area, wherein the first shielding member may be configured to at least partially block an electromagnetic field generated by the second coil interfering in the first conductive wire area.
