Abstract
Apparatus is provided for improving the coupling between an external inductive transmitting coil and an internal inductive receiving coil to transmit power and/or data to the receiving coil from the transmitting coil. The structure includes a coupling coil inductively coupled to the transmitting coil to increase the Q factor and hence the energy transfer between the transmitting coil and the receiving coil.
