A three‐port coplanar waveguide semiconductor circulator is analyzed. A theoretical 60‐GHz N‐type indium antimonide design at an operating temperature of 77 K is presented with a 20‐dB isolation bandwidth of approximately 25%. A six‐port microstrip ferrite circulator is also designed to provide a validity check using the ANSOFT TM High Frequency Structure Simulator. © 2002 Wiley Periodicals, Inc.
