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.
Claims17
A rotary joint providing a high speed datalink between rotatable parts comprising a circular channel,
- wherein the circular channel includes:
- an inner ring and an outer ring,
- both the inner and outer rings being centered about a common rotation axis and being rotatable against each other,
- the outer ring having a larger diameter than that of the inner ring,
- an inner antenna mechanically coupled to the inner ring, and
- an outer antenna mechanically coupled to the outer ring;
- wherein
- the inner antenna and the outer antenna are directed into a space between the inner ring and the outer ring and configured for a microwave signal connection (169) between the inner and outer antennae.
