Abstract :
A new current expansion technique that combines roof-top and triangular subdomain functions is used in full-wave analysis for characterization of microstrip discontinuities of arbitrary shape. This technique can simultaneously take advantages of the roof-top subdomain function for its excellent numerical convergence as well as the triangular basis function for its capability of simulating current density along a mitered edge. Detailed formalism has been given in this paper. Several examples will be presented to illustrate the efficiency of this technique
