Abstract

A full-wave analysis by the extended spectral-domain approach is successfully applied to solve the cylindrical coplanar-waveguide problem. The analysis incorporates the effects of the edge singularities properly and can afford the efficient and accurate calculation method for the characteristic impedances in addition to the phase constants of cylindrical coplanar waveguides (CCPWs) with zero- and finite-thickness conductor. The numerical results obtained by this method have revealed the effect of conductor thickness on the characteristics of higher order modes, as well as the odd and even dominant modes of CCPWs for the first time.
