Abstract
A multilayered printed circuit board with circuit trace windings having two or more top layers, two or more bottom layers and one or more intermediate layers therebetween, forming a hollow interior within the circuit board. The layers have wireless electrically conducting holes. Electrical circuit traces connect one hole to another hole, thereby forming two or more sets of wireless circuit trace windings (coils) around the hollow interior. Each set of windings has its own separate pair of a top layer and a bottom layer. When a metal core is positioned in the hollow interior a wireless transformer can be formed having a primary coil and one or more secondary coils. Because the coils are concentric sufficient windings can be achieved to produce adequate magnetic flux for power transfer.
