Abstract
A coil assembly is disclosed. The coil assembly includes a coil that is provided on a substrate. The coil includes a trace element that is wound on the substrate. The trace element includes an interior gap that extends or is present along at least a portion of the trace element. The interior gap is dimensioned to reduce a presence of eddy currents that would otherwise be generated when the coil is active to inductively transmit or receive signals.
