Abstract :
The dispersion and leakage characteristics of coplanar waveguides are treated using the spectral-domain approach together with the complex residue technique. To handle the complex propagation constant of the coplanar waveguide, the Fourier transform and Parseval´s theorem in the complex plane are extended. A number of numerical results, such as the effective dielectric constant and normalized attenuation constant, are presented to illustrate the characteristics of the coplanar waveguide. Sharp peaks just after leakage together with broad peaks are two interesting phenomena observed in the attenuation characteristics. The physical mechanism of these peaks and the details of transition in the εeff and α/k0 curves are still unclear
