Abstract
The present disclosure provides a wireless charging coil, and the wireless charging coil comprises a first coil layer, a second coil layer and a first magnetic material. The second coil layer is stacked in parallel on a surface of the first coil layer to form a stacked structure, and it has a winding path identical to a winding path of the first coil layer. The first magnetic material is disposed on one side of the first coil layer and has a winding path which is different from the winding path of the first coil layer and with said side away from the second coil layer. Currents generated by a power source are evenly distributed in the stack structure to reduce a skin effect when the wireless charging coil is electrically connected to the power source.

A wireless charging coil, comprising:
- a first coil layer;
- a second coil layer stacked in parallel on a surface of the first coil layer to form a coil stacked structure, and the second coil layer having a winding path identical to a winding path of the first coil layer;
- and
- a first magnetic material disposed on a side of the first coil layer and having a winding path different from the winding path of the first coil layer, with said side away from the second coil layer;
- wherein the coil stacked structure evenly distributes currents to reduce a skin effect when the wireless charging coil is electrically connected to a power source.
A wireless charging coil, comprising:
- a first coil layer;
- a first magnetic material disposed on a side of the first coil layer and having a winding path different from the winding path of the first coil layer;
- and
- a signal guiding member connected between the first coil layer and the first magnetic material;
- wherein a second coil layer, a graphite layer or a second magnetic material is stacked on a surface of the first coil layer to form a stacked structure for evenly distributing currents to reduce a skin effect when the wireless charging coil is electrically connected to a power source.
