In everyday language waveguide rotary joint provides RF connections with the movable joint ensuring a consistent flow of signal with low insertion loss and good power-handling capabilities to exceed the maximum limits of the whole system.
Its primary characteristic is to allow at least one of the transmission line to rotate when it connects high-speed digital signals or high-frequency analog signals in the system. Waveguide rotary joint is used in almost all the high-frequency systems such as radars, air-traffic-control (ATC), surveillance systems, and satellite communications, etc.
Waveguide rotary joint is available in different styles on the basis of various mechanical configurations and can include digital signals, analog signals, and even fiber-optic signals. These Styles are –
1. I style rotary joint – The style is formed when both of the transmission lines are in a straight line
2. L style rotary joint – when one transmission arm forms ninety degrees angle with another arm.
3. U style rotary joint – when both the transmission lines form a right angle with the centre of rotation.
4. F style rotary joint – the transmission arm at ninety degrees angle rotates while an in-line transmission arm is fixed to the housing.
You can gauge the performance of Waveguide rotary joint in terms of insertion loss and VSWR (voltage standing wave ratio) with leak rate, frequency, and torque.
