Analysis of H-slot resonators in microstrip line ground plane

Abstract

The strict generalized formulation of the transverse resonance technique (TRT) has been developed as a convenient formalization tool for discontinuities of increased complexity in planar and quasi-planar configuration such as stripline and slotline [1]. The idea of analysis technique of similar slotline structures is described in the work of Sorrentino, Itoh [2] where the field on discontinuity in a slotline is expressed through eigenwaves of a complex cross-section waveguide. Thus the boundary problem for eigenwaves of the waveguide in the area with rectangular coordinate borders can be solved by classical projection method.
