Abstract

A high-frequency conductor having improved conductivity comprises at least one electrically conductive base material. The ratio of the outer and inner surfaces of the base material permeable by a current to the total volume of the base material is increased by a) dividing the base material perpendicularly to the direction of current into at least two segments, which are spaced from each other by an electrically conductive intermediate piece and connected both electrically and mechanically to each other, and/or b) topographical structures in or on the surface of the base material and/or c) inner porosity of at least a portion of the base material compared to a design of the base material in which the respective feature was omitted. It was found that, as a result of these measures concerning the design, it is possible to physically arrange the same amount abase material so that a larger fraction of the base material is located at a distance of no more than skin depth from an outer or inner surface and is thus involved in current transport. As a result, a lesser fraction remains unused as a function of the skin effect.
