Abstract: This paper presents a set of newly developed computeraided-design-oriented formulas for the evaluation of the quasi-static evenand odd-mode characteristics of conductor-backed coplanar-waveguide (CBCPW) coupled lines. This set of expressions is evaluated using a conformai mapping method based on the assumption of pure transverseelectromagnetic propagation. The result for the odd- and even-mode characteristic impedance and effective dielectric constants computed by these formulas agrees well with the result evaluated from the existing formulas of both Wadell and Hanna. However, the new expressions derived provide a more systematic and efficient method for calculating the essential parameters of CBCPW coupled lines as compared to the existing ones in [1] and [2J. © 1999 IEEE.
