Abstract: The hybrid-mode mixed spectral domain approach (MSDA) is formulated to investigate the dispersion nature of multiple coupled microstrip lines with arbitrary metallization thickness, Incorporated into the solution procedure, a new set of basis functions with delta(-1/3) field singularity near conductor edges is found to be effective in calculating both the phase and attenuation constants, The computation of conductor loss is based on the perturbation procedure, Over a broad band of frequency spectrum, excellent agreement is obtained between the calculated results and existing experiment data for the metallic losses of a single microstrip and effective dielectric constants of coupled lines, The influence of finite metallization thickness on the frequency dependent modal propagation and attenuation characteristics is presented for both a three-line and four-line structure.
