Abstract
A sparse routing coil structure for a magnetic coil in a wireless charging system is disclosed. The sparse routing coil structure may include a magnetic coil routed by turns of a wire and a turn spacing S between adjacent turns of the wire. The turn spacing S may be a space between adjacent turns of the wire, and a turn width is denoted as W. A ratio of W/S may be not larger than 10.
