Abstract
The present invention provides a multiple coil structure for supporting multiple types of charging and near field communications. The multiple coil structure includes an inner charging coil comprising a first conductor path forming one or more loops, wherein the direction of travel of the conductor path from an end point of the first conductor path is one of a substantially clockwise direction or a substantially counter-clockwise direction, and wherein the inner charging coil has an inner boundary and an outer boundary. The multiple coil structure further includes an outer charging coil comprising a second conductor path forming one or more loops, which extend around the outer boundary of the inner charging coil, wherein the direction of travel of the conductor path from an end point of the second conductor path is one of a substantially clockwise direction or a substantially counter-clockwise direction, and wherein the outer charging coil has an inner boundary and an outer boundary. The multiple coil structure still further includes a near field communication coil comprising a third conductor path forming one or more loops within the inner boundary of the inner charging coil, wher…
