Abstract: A novel broadband 8mm E-plane T-junction waveguide with off-center ferrite discs was developed.From analysis and the simulation of HFSS9,the performance of the circulator was gained approximately.Good agreement between the simulation and the result of measurement was observed.The results of experiment show that the method is useful to widen frequency band.Compared with early E-plane T-junction circulator,the circulator has a better performance in VSWR,isolation and insertion loss(VSWR1.4,isolation17dB,insertion loss0.7dB)in a rather wide frequency band(27.1-29.1GHz).
