Pulse propagation on Microstrip transmission-line uUsing an anisotropic substrate

This paper describes the effect of anisotropy on the pulse propagation in microstrip like structures for 0 Lt w/h les 10 anisotropic ratio 0.5 les n les 3 for both low and high permittivity substrates. The anisotropic substrate is transformed into an electrically equivalent isotropic substrate such that the line capacitance in both cases is identical. Using this dispersion model of anisotropy for all anisotropic substrate, shows the behavior of the transient signal propagating on the microstrip transmission line based components and shows how can control the distortion [7], amplitude, ringing, and pulse shape of the transient signal [10].
