- Abstract
In this paper, a general design method for a special kind of N-channel rotary joint is presented. The N-channel configuration is achieved by using transition between concentric coaxial lines and double-ridged waveguides. Design of double-ridged waveguides for the purposed transition is also presented. Based on this method, an ultra wide band six-channel rotary joint is designed for a frequency band of 8 to 18 GHz. A full-wave numerical simulation tool is used to optimize the geometry of the proposed six- channel rotary joint to achieve a compact size, wide bandwidth operation, and low insertion loss. Simulated results show the insertion loss of less than 0.5 dB and VSWR ≤ 2 for all channels over the entire frequency bandwidth. Finally, the sensitivity analysis is done to obtain the effect of the manufacturing tolerances on performances of the rotary joint.
