Coplanar-to-rectangular waveguide millimeter-wave transitions manufacturing tolerance analysis using the finite-element method
A 94.5-GHz coplanar to rectangular transition for satellite telecommunications is analyzed via the finite-element method (FEM). Particular attention is devoted to the effects of manufacturing tolerances, and a full statistical behavior, extracting the effects of single geometrical details, is presented. Obtained data are validated by the measurements of the prototypes. (c) 2006 Wiley Periodicals, Inc.
