Printed circuit antennas with integrated FET detectors for millimeter-wave quasi optics

Planar twin dipole microstrip antennas with integrated FET detectors which provide antenna patterns suitable for millimeter-wave quasioptical applications are discussed. The circuits are suitable for use as individual elements of an imaging array. A 63-GHz heterodyne mixer using such a circuit produced a system noise temperature of 7900 K.<
