This paper discusses the different steps that must be followed for the design of a Wireless Power Transfer receiver implementing an ad-hoc coil. The Wireless Power Transfer receiver follows the Qi standard but the receiver coil geometry is constrained by the application so that the coupling factor is degraded. Careful load-line simulation and validations tests show that it is possible to design a compact receiver with low coupling factor based on the Qi standard.
