The CAD oriented closed-form models are presented to compute frequency and conductor thickness dependent effective relative permittivity and characteristic impedance of a slot-line with finite conductor thickness in the range 3 μm-50 μm. The models have average accuracy about 2% against the full-wave results from different sources in the frequency range 2 GHz-60 GHz, 2:22 ≤ ε r ≤20, 0:02 ≤ w/h ≤ 1:0, 0:01 ≤ h/λ o ≤ 0:25/√(ε r-1). The models to compute the dielectric and conductor losses are also presented that show close agreement with the results of the spectral domain analysis. The average deviations for the dielectric and conductor losses are 0.011 Np/m and 0.143 Np/m against the results of SDA in the frequency range 2 GHz-30 GHz for narrow to wide slot-width.
