On the cutoff wavelength of V-shaped microshield line by edge element method

In this paper, the cutoff characteristics of V-shaped microshield line has been analysed by edge element method. Dependence of cutoff wavelength on the thickness of metallic signal strip, dielectric constant of dielectric substrate and the vertex angle of the V-shaped ground conductor are presented in tabular forms. Numerical results in this paper have important values in the design of V-shaped microshield lines in microwave and millimeter wave integrated circuits.
