Abstract
A coupler provides a high speed datalink between rotatable parts, which includes comprising a circular gap shaped as a hollow-cylindric volume and at least two antennae. The gap is formed between a first ring and a second ring rotatable against the first ring. A first antenna is mechanically coupled to the first ring and a second antenna is mechanically coupled to the second ring. The antennae are configured to effectuate a microwave signal connection between them the antennae based on multiple reflections of the signal at the rings.
Claims20
A high speed datalink rotary joint
- comprising:
- a first ring with a first diameter and a second ring with a second diameter that is larger than the first diameter,
- the first ring being coaxially arranged to the second ring and around a center axis to form a gap between the rings,
- the first ring and the second ring comprising at least partially conductive material,
- the rotary joint further comprising a first antenna and a second antenna rotatable relative to the first antenna,
- the first antenna being directed into the gap in a first direction and at a first angle,
- the second antenna being directed into the gap in a second direction opposing the first direction and at a second angle (332), and
- wherein each of the first angle (331) and the second angle is defined relative to a radial direction of the center axis and has an absolute value in a range from 0° to 90°,
- wherein each of values of the first angle and the second angle is a fixed value and remains over rotation.
A rotary joint according to claim 13, wherein
- each of the transmitter, the receiver, and first and second transceivers is configured for OFDM or single carrier with frequency domain equalization.
