Coupled lines with double shields for microwave hybrids of various types of directivity with transforming properties

Abstract: Asymmetric coupled double-shielded lines in an inhomogeneous dielectric medium, which have special properties that allow us to create microwave hybrids of a given directionality type are investigated. For the first time, a new model and method of synthesis are proposed, which takes into account both the asymmetry and the inhomogeneity of the dielectric, which makes it possible to synthesize co-, counter- and transdirectional couplers that have both the transforming and required phase properties. The research results will be useful for finding new design solutions of the next generation microwave circuits.
