Abstract
A wireless device is provided and includes a substrate, a first coil and a second coil. The first coil is configured to be wound around a first axis, and the first coil is disposed on the substrate and is configured to operate in a wireless charging mode. The second coil is disposed on the substrate and configured to operate in a wireless communication mode. The wires of the second coil partially overlap the wires of the first coil.
