Abstract

A novel MM-wave coplanar waveguide (CPW) folded slot antenna is characterized on a low-resistivity Si substrate (1 Ω-cm) and a high resistivity Si substrate with a polyimide interface layer. The antenna resonates around 30 GHz with a return loss greater than 14.6 dB. Measured radiation patterns indicate the existence of a main lobe, but the radiation pattern is affected by a strong surface wave mode, which is greater in the high resistivity Si wafer.
