One straight and one RA (L-shaped) Microwave Waveguide Rotary Joints
Waveguide rotary joints are mainly used for signal transmission for the connection of fixed and rotating parts. Waveguide rotary
joint ports involve coaxial, rectangular waveguide ports and ridge waveguide ports. Types include: single-channel
waveguide rotary joints and multi-channel waveguide rotary joints, which are categorized into I-type, L-type and U-type
according to their structural form.

Application:
- Radar system: Waveguide rotary joint is the key device in the mechanically scanned radar antenna feedline system. It can ensure the efficient transmission of microwave signals in the feedline while the radar antenna rotates 360°, ensuring that the radar system can accurately detect and track targets.
- Aerospace field: In the aircraft, avionics equipment, waveguide rotary joints are used to realize signal transmission in different directions, to meet the needs of communication and navigation in various attitudes of the aircraft. For example, in the aircraft's airborne radar, communication antennas and other equipment, waveguide rotary joints can ensure stable signal transmission in different directions.
- Satellite communication: In the satellite communication system, waveguide rotary joints can be used in the rotating part of satellite antenna to enable the satellite to maintain a stable communication connection in the orbit, and at the same time, it can be adjusted in attitude according to the need to realize the coverage of the ground or other satellites.
- Industrial automation: In some industrial automation equipment, such as rotary robots and automated production lines, waveguide rotary joints can be used to realize signal transmission and control within the equipment, improving the flexibility and reliability of the equipment.
