Abstract

New design data for an open suspended microstripline is reported. Two most commonly used substrate materials, namely RT-Duroid (ɛr=2.22) and fused quartz (ɛr=3.78) are considered. Effects of dispersion and strip thickness are included in the results which are based on a fullwave spectral-domain analysis. The data, which is computed over the complete practical ranges of frequency and parameter values, is much more reliable than the currently available quasistatic results.
