Dispersion analysis of square pulse with finite rise time in single, tapered and coupled microstrip lines

The distortion of an electrical pulse with finite risetime caused by dispersion as it propagates along a uniform microstrip, a tapered microstrip, and a coupled pair of microstrips is investigated. Closed-form analysis equations for a single microstrip and for coupled microstrips and an algorithm for a numerical quadrature technique for evaluation of the inverse Fourier transform have been used. The results are useful in the time-domain analysis of many circuit components where such microstrips are used.<
