Abstract

See full text

A coil assembly includes a coil winding and a multilayer printed circuit board. The coil winding has multiple loops that are arranged in different layers of the printed circuit board and form a main magnetic field with a main measuring direction perpendicular to a main plane of the printed circuit board. The loops arranged in different layers are electrically connected together via at least one via. The printed circuit board has at least four vias or a whole-number multiple of four vias that form an equal number of reverse current paths and forward current paths between the loops of the coil winding. Each pair of vias with the same current path direction is arranged point-symmetrically relative to a common mirror point such that magnetic loops that are formed on printed circuit board secondary planes arranged perpendicularly to the main plane have opposite directions and compensate for one another.
