The partial capacitance approach and conformal mapping techniques are
used to evaluate simple closed-form models for parallel and series cap
acitances of equivalent pi-network of a symmetric gap in a CPW. Models
are compared with experimental data and full wave analysis. They are
useful for a wide range of CPW parameters and frequencies. (C) 1996 Jo
