摘要: Abstract Antenna patterns of open structure Schottky mixers were measured at 184, 214 and 287 μm. For use in a heterodyne detector system the antenna pattern must be matched to signal beam, for example astronomical telescope, optically coupled local oscillator beam. The procedure determining lens is described successful application observations with Kuiper Airborne Observatory (KAO) shown.
