Abstract :
This paper presents a full-wave FDTD analysis of open/shielded microstrip discontinuities on anisotropic substrates through the evaluation of their S parameters. A wideband Gaussian pulse excitation was used to obtain frequency-domain information from dc up to the desired cutoff frequency. Numerical results demonstrate the necessity to include the effect of dielectric anisotropy in the modeling of microstrip discontinuities.
