A simplified formula for the characteristic impedance of a coplanar waveguide (CPW) has been proposed. The formulation is based on the determination of the static capacitances between parallel strips and is found to be valid even up to zero gap width.

Inspec keywords: electric impedance; waveguide theory; waveguides

Other keywords: characteristic impedance; static capacitances; coplanar waveguide; parallel strips

Subjects: Waveguide and cavity theory
