Abstract:
1. A multilayered printed circuit board having circuit trace windings, comprising: a) two or more top layers, two or more bottom layers and, one or more intermediate layers therebetween; b) each said intermediate layer has an open interior so that said two or more top layers, said two or more bottom layers, and said intermediate layers form a hollow interior within said multilayered printed circuit board; c) each of said two or more top layers, two or more bottom layers, and one or more intermediate layers having a plurality of electrically conducting holes wherein, when one said electrically conducting hole contacts another said electrically conducting hole, an electrical conducting connection is made therebetween; d) electrical circuit traces on said two or more top layers and said two or more bottom layers wherein said electrical circuit traces connect one electrically conducting hole to another electrically conducting hole, wherein said electrical circuit traces form connections across said two or more top layers and said two or more bottom layers, and wherein said electrically conducting holes form electrical connections between said two or more top layers, said intermediate layers, and said two or more bottom layers, thereby forming two or more sets of wireless windings around said hollow interior; and e) said one or more intermediate layers having no said electrical circuit traces.
