Abstract :
A coplanar waveguide which consists of a strip of metallic thin film on the surface of a dielectric slab with two ground electrodes running adjacent and parallel to the strip is easily accessible for shunt connections of semiconductor devices. This letter presents experimental data, and a theoretical equation including correction factors, for an effective relative permittivity concerning characteristic impedance. The measurements have been made by the t.d.r. method.
