High Bandwidth Contactless Rotary Transmitter Design Optimized for Baseband Transmission

Abstract

This paper describes a novel system engineering approach of a rotary transmitter with a free rotating center. First, the basic architecture is classified and compared with common rotary transmitter designs. Second, a basic model is used to develop an optimizing strategy for the physical channel, to achieve channel characteristics suitable for baseband transmission systems. Furthermore, difficulties of a multichannel architecture are outlined before developing suitable solutions. Finally, the concept is verified practically with the help of a 1000Base-T Ethernet rotary transmitter.
