Microwave filter based on crystal-like reactive elements

Abstract

The models of reactive elements, called δ-models, that unlike conventional models without frequency limitations are proposed. On the basis of δ-models of low-pass filters microstrip filters based on 3D electromagnetic-crystal inhomogeneities, which combine inductive and capacitive elements is proposed. Calculated and experimental characteristics of the filter illustrating characteristic improvement and reduction in size compared with conventional solution are presented.
