The hybrid integration of a dielectric antenna together with an MMIC low-noise amplifier in a 60 GHz front-end is presented. It is demonstrated how a low-loss substrate integrated dielectric antenna can efficiently be interconnected at miniature scale with the coplanar waveguide input of the MMIC. The experimentally obtained return loss is better than 11 dB from 55 to 65 GHz. Transmission path loss measurements of a wireless link confirm the low-loss potential of this approach for millimetre-wave front-ends.
