Abstract
An antenna for wireless power transmission. A first coil portion includes a first outer coil portion and a first inner coil portion. A second coil portion includes a second outer coil portion and a second inner coil portion. The first coil portion and the second coil portion are disposed to overlap and intersect each other at one or more points. In a state in which the first coil portion and the second coil portion are overlapped, bends of the first coil portion and the second coil portion overlap and intersect each other. All of the bends of the first outer coil portion are located above the bends of the second outer coil portion or all of the bends of the second outer coil portion are located above the bends of the first outer coil portion. Uniform charging efficiency is obtained across entire areas.
