An input end of the OMT common port is connected to a single polarization antenna, one end of the OMT feeder is connected to an output end of the OMT common port, and an other end of the OMT feeder is connected to the polarization separated core, the OMT feeder has a tubular structure, and horizontal and vertical axes of an inner wall cross section of the OMT feeder are unequal, or a tuning rod is disposed in a tube of the OMT feeder and is perpendicular to an extension direction of the tube, and a vertical polarization port and a horizontal polarization port are disposed in the polarization separated core, the vertical polarization port transmits a vertical polarization wave, and the horizontal polarization port transmits a horizontal polarization wave.
Compact integrated rotary joint
A rotary joint includes a first part and a second part configured to rotate around a rotation axis against the first part. The first part has a first magnetic core, a sliding brush, and a capacitive data link component. The second part has a second magnetic core for coupling power with the first magnetic core, a sliding track for galvanic coupling with the sliding brush, and a second capacitive data link component to transfer data from and/or to the first capacitive data link component. To weaken magnetic stray fields from the magnetic core, the rotary joint is a disc-type rotary joint, and the sliding track is arranged radially between the second magnetic core and the second capacitive data link component.
Rotary Transmission System Using a Waveguide
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.
