発明の概要(英語)

[Problem] To provide a transmission line capable of deterring an insertion loss attributable to a skin depth. Also, to provide a value-added transmission line that utilizes said feature. [Solution] This transmission line comprises conductor layers (A) having a positive magnetic permeability and conductor layers (B) having a negative magnetic permeability. The thicknesses of layers A and layers B are set such that magnetic fluxes of adjoining layers are diminished (cancelled out). Because the magnetic flux density is distributed in accordance with distances from the center such that the density becomes lower toward the center and becomes higher toward the outside, the cancel effect can be improved by setting the thicknesses of the layers thicker toward the center and thinner toward the outside. This circuit board is equipped with a substrate and a transmission line that is provided on the top surface of the substrate, wherein the aforementioned transmission line is used for this transmission line. This high-frequency device is equipped with a transmission line, wherein the aforementioned transmission line is used for this transmission line.
