Cross Section of Coplanar Waveguide Transmission Line

A Coplanar Waveguide is a transverse electromagnetic (TEM) transmission line medium[1].

Description

[edit]

A Coplanar Waveguide circuit uses a flat strip of metal with two ground planes either side. The insulating material of the substrate forms a dielectric. The width of the strip, the thickness of the substrate and the relative permittivity of the substrate determine the characteristic impedance of the strip which is a transmission line[1].
