Abstract :
Based on an improved formulation of the singular integral equation method for microstrip and suspended substrate lines, their discontinuities including arbitrary composition of steps are analyzed using the mode-matching method. Results show that previous analyses using mode matching were not sufficiently accurate. The influence of complex modes is discussed. A computer program has been developed to deal with cascaded discontinuitiesl; it includes arbitrary composition of step discontinuities.<>
