Abstract
This disclosure pertains to wireless power transfer systems, and in particular (but not exclusively), to techniques to improve the coupling efficiency between a power transmitting unit and a power receiving unit within a computing device. The present disclosure includes a system which comprises a computing unit which includes a power receiving unit and a conductive surface. The conductive surface has an opening that is adjacent to the power receiving unit and a slot extending from the opening towards the perimeter of the conductive surface. The computing unit further includes a system base coupled to the power receiving unit wherein the power receiving unit is to provide power to the system base. The system also includes a power transmitting unit adjacent to the computing unit.
