Abstract
Fast and accurate analytic formulas for calculating the quasistatic transverse electromagnetic (TEM) parameters of a general broadside-coupled coplanar waveguide (GBSC CPW) are presented. Simplicity, high speed of computation, and accuracy suggest the use of these formulas for (M)MIC CAD (monolithic) microwave integrated circuit computer-aided design programs. Numerical calculations are presented to investigate various electrical properties of the structure. An asymmetrical BSC CPW and the single CPW resulting from connecting the two coupled strips of the GBSC CPW at the input and the output ports are analyzed. Criteria are obtained to ensure the coplanar behavior of the structure.Keywords
