Abstract

A full-wave analysis based on a spatial-domain moment method is obtained for finding two-dimensional current distributions and hence the scattering matrix for chamfered bends and other microstrip junctions of general shape in MMICs (monolithic microwave integrated circuits). The numerical simulation program can provide useful design information as well as physical insights for frequencies high in the millimeter-wave range. The analysis is applied to a right-angle single bend, with and without a chamfered corner, and a right-angle double bend. The scattering matrix for each case is deembedded from the current distribution obtained from the p-mesh model. The program can be run on an HP-300 workstation or a supercomputer depending upon the number of cells of the desired accuracy for a given problem.
