A Coplanar Waveguide with Thick Metal-Coating (Short Papers)

A theoretical method is presented for the analysis of a coplanar waveguide, with thick metal-coating. Numerical results are given and compared with published data. It is shown that the metal-coating thickness of the coplanar waveguide causes an increase in wavelength and a decrease in characteristic impedance and that the changes are about the same as those of a slot line.
