Small Aperture Coupling in the Applications of Circular Groove Waveguide

Reciprocity theorem and small aperture's equivalent method are used to analyze the coupling problem between circular groove waveguides, a formula of the aperture's equivalent reactance is obtained; Then the coupling between the circular groove waveguide and circular groove waveguide cavity is discussed; Finally, numerical results are compared with experimental ones. They are in good agreement. It verifies the validity of the analytical method.
