Resumen

In this paper, we extend the Multimode Equivalent Network (MEN) formulation for the analysis of encapsulated microwave components that are composed by metallizations with a non-negligible thickness. To accomplish this goal, the analysis is divided in two steps: first we formulate two different equivalent networks corresponding to the two thick steps present in the structure, and then we cascade them to obtain the final network that characterizes the complete circuit. This theoretical approach is validated through two practical microwave bandpass filters. We experimentally demonstrate in these examples that zerothickness approximations are not accurate to solve this kind of problems, thereby demonstrating the importance of the MEN extension proposed in this contribution.
