Abstract :
The offset parabolic antenna of Cassegrain type with quasioptic duplex device at 94 GHz band is described. Antenna is based on properties of circularly polarized waves, provides isolation more than 78 dB in wide frequency range and is intended for using in systems with continuous radiation (radar, communications etc.).
