Abstract

A coupler provides a high speed datalink between rotating parts and comprises a circular channel, enclosing a hollow-cylindric volume, and at least two antennas. The circular channel is made of electrically conductive material and includes an inner ring, an outer ring rotatable against the inner ring, and two sidewalls on the sides of the rings. An inner antenna is mechanically coupled to the inner ring and an outer antenna is mechanically coupled to the outer ring. The antennas are configured to establish a microwave signal connection between them based on multiple reflections of an electromagnetic wave at the rings.
