“…The recent development and popularization of 3D EM tools, usually based on Finite Element Method, Method of Moments, Finite Integration Technique, etc, has pushed the designers to the tailored ad‐hoc application of numerical methods, but used in a manner more focused on obtaining the best performance than on getting reliable and repetitive functionality. From this point of view, a Monte Carlo tolerance analysis in complex structures (such as waveguides or transitions) has a great importance to obtain an acceptable performance of the design. Moreover, the availability of simple, but accurate equivalent circuit models of the transitions would be of interest for system designers .…”

This work presents a comprehensive design protocol for a W-band E-plane waveguide-to-microstrip transition covering all aspects, from the probe design, matching, cut-off cavity size estimations, verification analysis with different 3D EM simulators, and the entire fabrication process, with special emphasis on tolerances and yield with optimized costs. In fact, a complete study of the manufacture yield is done without the need to fabricate a large number of units of the microstrip-to-waveguide transition by taking advantage of the Monte Carlo tools embedded in 3D EM simulators. A simple equivalent circuit model of the transition is proposed and validated to be used in W-band system level simulations. These are requirements to enable massive use of W-band products (i.e., concealed weapons detection, imaging, etc.) with reasonable costs. V C 2013 Wiley Periodicals, Inc.

A domain decomposition approach is here applied to the finite element solution of a multiport waveguide passive device. The approach allows separating the problem in multiple, coupled subproblems which can be solved individually. By appropriately defining one of these subdomains as containing all the possible variations to be studied it is hence possible to restrict the tolerance analysis to this latter, smaller domain. Numerical results showing the gain in computing time are presented.

Abstract-A full-wave analysis of the scattering parameters of a straight-to-bent microstrip line coupling is performed using a FEM technique. The numerical results, showing the influence played by the geometrical parameters of the structure on the electromagnetic coupling, are then employed to derive an equivalent circuit useful to be employed in CAD tools. A third order polynomial approximant useful to compute the equivalent circuit elements is finally provided.
