In this study CAD-oriented analytic expressions derived by the conformal ma
pping method are presented, for the first time, for calculating the line pa
rameters of a rectangular-shaped microshield CPW on a cylindrical substrate
. The effect of the curvature on the line parameters is discussed. In addit
ion, this papers results are compared with the results available in the lit
erature for a rectangular-shaped microshield coplanar waveguide on a planar
substrate. (C) 2001 John Wiley & Sons, Inc.
