Abstract
A device for signal transmission between units that are movable along given tracks comprises at least one transmitter for generating electrical signals, at least one conductor arrangement for conducting the electrical signals along a track of movement, and at least one receiver for coupling out electrical signals from a conductor arrangement. At least one conductor arrangement comprises at least one conductor structure for conducting electrical signals, an electric reference surface assigned thereto, and at least one dielectric between the conductor structure and the reference surface. A dielectric of the kind used has a high homogeneity, or a high symmetry with respect to the electrical center of the longitudinal axis of the conductor structure, or both.
