ABSTRACT:
An improved waveguide circulator that eliminates the need for quarter-wave dielectric transformers or impedance steps in the interface waveguide for broadband operation is described. The circulator designs in the prior art all require impedance matching elements outside of the ferrite element in order to achieve acceptable performance. Through the use of this new invention, broadband circulator performance can be achieved without the addition of impedance matching elements in order to minimize the cost, size, mass, and loss of the circulator.
