Abstract :
This paper presents an approach to the design of three-port H-plane waveguide Y-junction circulator with two partial height ferrite posts in the junction region which has the advantages of high isolation and low insertion loss. With 9.375GHz center frequency and 400MHz bandwidth, the X-band waveguide circulator designed with the approach could be used in microwave measurement systems, whose VSWR is less than 1.2, insertion loss is less than 1dB and isolation is more than 20dB, which could be used in medium power systems and high power systems.
