Abstract
We have included losses in the analysis of a 3N-port stripline/microstrip circulator and have reformulated the circulation conditions previously postulated for the lossless case. Our calculations have been compared to three published data on circulator designs biased below and above ferrimagnetic resonance. Scattering parameters at each port have been calculated as a function of assumed material losses and coupling capacitance of a multiport circulator. Wide transmission band or wide stop bands may be possible for a six port circulator biased above ferrimagnetic resonance.
