Abstract

The magnetic field distributions of a CPW semiconductor junction circulator are computed at different frequencies for the first time. The results resemble the electric field distributions of a six-port microstrip ferrite junction circulator simulated using Ansoft HFSS. A broadband CPW semiconductor circulator centered at 60 GHz has been designed by tracking the perfect circulation curves from the region where /spl epsi//sub eff/>0 up to the region where /spl epsi//sub eff/<0.
