Patent ID: 7212077

Claim:
Device for signal transmission between units movable along given tracks, comprising: at least one transmitter for generating electrical signals; at least one conductor arrangement for guiding at least one of the electrical signals of at least one transmitter along a track of movement; and at least one receiver movable relative to the transmitter along the at least one conductor arrangement for coupling out electrical signals from the at least one conductor arrangement, in which the at least one conductor arrangement comprises: at least one conductor structure for conducting electrical signals; at least one electrically conducting reference surface assigned to each conductor structure; at least one dielectric between the conductor structure and the reference surface; wherein the at least one dielectric having a high homogeneity or a high symmetry with respect to the electrical center of the longitudinal axis of the conductor structure, or both, is provided; and wherein at least one additional layer of conductive material, or conductive material having an incomplete surface coverage is provided.
