Re. Neidert et Pm. Phillips, LOSSES IN Y-JUNCTION STRIPLINE AND MICROSTRIP FERRITE CIRCULATORS, IEEE transactions on microwave theory and techniques, 41(6-7), 1993, pp. 1081-1086
This paper describes a complete theory to calculate the dielectric, co
nductor, and magnetic losses of Y-junction stripline and microstrip fe
rrite circulators in terms of 3-port S-parameters. Calculations using
this theory are presented, and compared with existing data for varied
circulator parameters over a frequency range of 1-100 GHz.
