Abstract
A printed circuit board (PCB). The PCB comprises a non-conductive substrate and a plurality of conductive coil loops formed on the substrate, wherein the coil loops are asymmetric. The conductive coil loops are formed as a continuous metal trace on the substrate, the coil loops are symmetric with reference to a longitudinal axis of the PCB, the coil loops are asymmetric with reference to an axis transverse to the longitudinal axis of the PCB, wherein the distance between adjacent coil loops crossing the longitudinal axis on a first side of a center of an innermost coil loop are substantially equal, and the distance between adjacent coil loops crossing the longitudinal axis on a side of the center of the innermost coil loop opposite to the first side of the center of the innermost coil loop increase with each coil loop progressing outwards.
