Single Channel Waveguide Rotary Joint

Rotary Joints (rotary couplers) are used to transmit microwave energy from stationary lines to rotating lines. The rotary joint is an electro-mechanical device with RF performance dependent upon rigorous electrical and mechanical design. Available styles are defined by physical geometry as follows:
I-style - Two in-line arms both collinear with the axis of rotation.
L-style - One arm is perpendicular to the axis of rotation.
U-style - Both arms are perpendicular to the axis of rotation.
