Abstract:

This memorandum describes a theoretical procedure for the design of microstrip circulators on all ferrite substrates and substantiates its validity by using it to fabricate and measure a circulator for 9.3GHz agreement between theory and practice was good. New information included in the theory consists of an extension of recent work by Wolff and Knoppik on microstrip disc capacitors to include the magnetic properties of the ferrite, leading to a much more accurate value for the disc radius of the circulator. Use of the theory to calculate the resonant frequency of an alternative type of microstrip circulator in which a cylinder of ferrite is inserted in a hole in another dielectric also gives more accurate results than previously used theory.
