Abstract: Coplanar waveguides have a center signal line and a pair of ground lines on either side formed of a sputtered material such as gold (Au). Such waveguides are subject to what is known as the edge effect at high frequency operation causing currents to concentrate and flow along adjacent edges of the lines. Providing a thicker plated layer only on adjacent edges of the lines provide substantial performance improvements over sputtered lines alone while saving significant amount of Au, thus reducing costs.
