Coil techniques

Abstract

Techniques are disclosed involving coils that may be used to exchange wireless energy between devices. For instance, a device may include a coil having a plurality of turns arranged along an arc. Further, the coil may have first and second ends that are substantially normal to the arc. The coil may be arranged within a casing of the device. This casing may have first and second non-parallel surfaces. In embodiments, the first end of the coil may be directed to (be substantially parallel with and proximate to) the first surface, while the second end of the coil may be directed to the substantially parallel with and proximate to) the second surface. The coil may be employed in wireless power transfer and/or near field communication applications.
