Abstract :
A full-wave analysis of the coplanar waveguide (CPW) printed on a cylindrical substrate is presented, and the dispersion characteristics of the cylindrical CPW are studied. Numerical results of the effective relative permittivity are calculated using a Galerkin´s moment-method calculation. Experiment is also conducted, and the measured data are in good agreement with the theory
