Abstract :
Broadside-coupled microstrip with and without conducting side walls is studied using a full-wave spectral-domain analysis. Special attention is directed towards possible leakage to the parallel plate mode and its potential effects in practical integrated circuits. It is asserted that for certain geometrical parameters, broadside-coupled microstrip can be leaky at all frequencies. Comparisons between the modes on broadside-coupled microstrip with and without side walls are made by means of dispersion curves.<>
