Abstract

This paper deals with the design and simulation of a waveguide rotary joint using gap waveguide technology for millimeter wave applications. It contains two TE10 to TM01 mode converters and rotary junction between two circular waveguides. The mode used along the circular waveguide for rotational symmetry purpose is TM01.The most important advantage of using gap waveguide technology is its ability to decrease complexity and cost of fabrication especially in millimeter wave frequencies because there is no requirement of contact between the different parts of the rotary joint structure. The Simulation results show that at different rotation angles the insertion and return loss are better than 0.4 dB and 10 dB over 58.5 GHz to 61 GH frequency band.
