Abstract: Vertical solenoid inductors have windings or layers which are arranged to minimize interwinding capacitance between adjacent layers. Each layer occupies a surface area, and adjacent layers are arranged to occupy different surface areas, except where necessary to provide electrical connection between adjacent layers. The inductors are high power inductors which have high inductances L and high current capabilities. The inductors of the present invention also have high self resonant frequencies and quality factors, while minimizing component volume.

Abstract: Conductive apparatus having minimized AC resistance. The conductive apparatus comprises a planar rectangular conductor having top and bottom surfaces, and opposed end surfaces that are smaller in dimension than the top and bottom surfaces. Magnetic material is disposed adjacent to each of the end surfaces of the rectangular conductor that is formed in a "C" shape to provide end caps that are symmetrical and enclose the end surfaces and portions of the top and bottom surfaces to overlap the conductor in its corners. A method of fabricating the conductive apparatus is also disclosed.

Abstract: An approach that minimizes ground plane effects affecting planar inductors is disclosed. A magnetic disk is inserted between an inductor and a ground plane to isolate the magnetic field of the inductor and preserve its magnetic characteristics. The present invention isolates the inductor from the ground plane to maintain or improve inductor electrical performance. The magnetic material serves to increase the inductance to its original value (prior to adding the ground plane) with only a slight degradation in Q due to an increase in AC resistance. This approach permits development of higher current, higher power printed networks, components and circuits whose circuit designs have decreased volume, weight, and cost.
