Abstract :
The design of a flat rotary joint with a very broad operating frequency band is described. The solution proposed here enables practical elimination of signal amplitude/phase and impedance changes considered as a function of rotation angle. Low transmission and reflection loss have also been achieved. According to experimental results presented in this paper, fractional bandwidth of the model exceeds 50%, with maximum SWR of 1.8
