Design of Broadband Waveguide Circulator at Ka-Band
This paper describes the design and implementation of a broadband (13% bandwidth) waveguide circulator at Ka band (29 GHz center frequency) for communication satellite payload. Design is based on three-port H-plane waveguide Yjunction circulator with a partial height ferrite posts in the junction region. RF and magnetic circuits simulation & optimization is performed using electromagnetic 3D CST software. Very low insertion loss of 0.13dB with better than 23dB return loss & Isolation has been achieved in the 27-31 GHz frequency band, measured performance are in close agleement with the simulation.
