Title: Broadband E-plane T-junction waveguide circulator with off-center ferrite discs
Abstract: E-plane circulator have good performance in high power microwave system with narrow bandwidth.A novel broadband 3 cm E-plane T-junction waveguide with off-center ferrite discs was developed.Getting help from the simulation of HFSS9 and analysis,the performance of the circulator is gained approximately first.Good agreement between the simulation and the result of measurement is observed.The result of experiment shows that the method was useful to widen frequency band.Comparing with early E-plane T-junction circulator,the circulator has a better performance in VSWR,isolation and insertion loss(VSWR1.2,isolation20 dB,insertion loss0.3 dB) in a rather wide frequency band(at 700 MHz).
