Abstract
Junction circulators in stripline and microstrip version are considered on the base of planar model analysis. The main steps of the proposed method includes: i) Replacing of the real structure of the coupling lines and disk resonator with its planar equivalents of the same height and characterized with effective dimensions and effective permittivity and permeability; ii) Assuming an approximate electrodynamical behaviour of the planar models the analysis of the investigated complicated microwave structures is done in closed-form and as a result of that the convenient expressions for the main junction parameters — Isolation and Return Losses are obtained; iii) Through a computer simulation an extensive information for the potential possibilities of the investigated junctions is easy obtained and in addition some new alternatives for the matching procedure are proposed. The planar model analysis is used for design of number stripline and microstrip circulators and isolators for communication and radar purposes.
