We have developed a novel planar integrated antenna-mixer structure. The device is constructed in parallel stripline (PSS), and consists of an endfire Vee antenna, R.F. matching filter, SIS junction array and I.F. output filter/matching network, sandwiched between a thick dielectric substrate and a similar dielectric superstrate. Expressions have been developed for the propagation constants and losses of PPS in finite thickness dielectric, and these have been confirmed by scaled modelling experiments.
