A GENERAL TREATMENT OF MATCHED TERMINATIONS USING INTEGRAL EQUATIONS-MODELING AND APPLICATIONS

This paper presents an original approach to simulate a broadband match ed load in planar structures. Theoretically, the formulation appears a s an additional boundary condition in the rigorous integral equations technique, and results in a partial rearrangement of the generalized i mpedance matrix in the moment method resolution. Practically, it enabl es the whole characterization of any planar multiport discontinuity in a procedure particularly realistic in regards to experimental measure ment procedures. This new refinement is demonstrated to provide a vers atile and powerful tool. Some typical applications are given which ill ustrate its numerous capabilities. The analysis of structures as diffe rent as a shielded microstrip step and an active receiving microstrip antenna is presented and successfully compared to experiments.
