Dispersion characteristics of unsymmetrical broadside-coupled striplines with anisotropic substrate

Dispersion characteristics of the unsymmetrical broadside-coupled striplines of unequal width are presented for the first time. The frequency-dependent hybrid-mode solutions converge to the quasistatic values at lower frequencies for various structural parameters of the broadside-coupled suspended striplines (BCSSs) and broadside-coupled inverted striplines (BCISs) with the anisotropic substrates.
