Abstract

By introducing the concept of "virtual relative permittivity," this paper reports several closed-form dispersion models for a multilayered shielded/unshielded microstrip line over 1 < ε_r < 20, 0.1 < (w/h) < 10, (h₃/h) > 2 in the frequency range up to 4 GHz · cm. The maximum deviation of the one model against the results of the spectraldomain analysis (SDA) is limited to 3%, while for the other three models, the maximum deviation is <2% and the root-mean-square (rms) deviation is <0.8%. This paper also reports improvement in the closed-form model of March for the determination of e_ff(0) of the shielded microstrip line.
