ABSTRACT:
A first stationary part or component possesses a first conductor arrangement which is coupled in a contactless manner with a second conductor arrangement located upon a second part or component. The second conductor arrangement contains two essentially rotationally symmetrical parts which build-up a toroidal electrical and/or magnetic field. The first conductor arrangement is arranged in the field of the second conductor arrangement. To fabricate the conductor arrangements there can be used existing technology for manufacturing printed-circuit boards. The inventive apparatus can be advantageously used, for instance, in radar installations, vehicles having a rotatable upper portion, such as a turret, turbines, generators and theodolites. The dual conductor arrangement of the inventive apparatus provides a functionally better de-coupling and therefore reduced cross-talk.
