Abstract
In accordance with embodiments of the present invention, a coil design for the transmission of wireless power. In some embodiments, the coil can include a winding with one or more turns of conductive traces mounted on a substrate, wherein the one or more turns include characteristics that enhance operation of the coil. In some embodiments, the winding includes a transmit coil and a receive coil, each coupled to terminals that provide for a transmit functionality and a receive functionality. In some embodiments, the traces are varied in width and/or thickness in order to optimize the inductance and the coil resistance. In some embodiments, parameters of a control circuit coupled to the coil to affect a transmit functionality or a receive functionality can be optimized.
