Abstract :
A novel mm-wave finite ground coplanar (FGC) folded slot antenna on a low-resistivity Si substrate (1 /spl Omega/-cm) with a polyimide interface layer is presented for the first time. The antenna resonates around 30 GHz with a return loss of 14.6 dB. Measured radiation patterns indicate the existence of a main lobe, but its radiation pattern is affected by a strong surface wave mode. This antenna can be part of various low cost wireless communication systems.
