Abstract :
In this work the paper presents the effect of parasitic moding on the mm-wave (140-220GHz) performance of coplanar waveguide (CPW) components on GaAs substrates as a function of substrate thickness and layout geometries. It is observed that mm-wave energy leakage especially at 220GHz is quite significant, i.e. as high as 9 dB for a standard short structure fabricated on 630 mum
