W-Band Cassegrain Antenna

SAY-7138634212-110-S1 is a W-band Cassegrain antenna that offers a nominal gain of 42 dBi and a typical half power beamwidth of 1.3 degrees from 71 to 86 GHz. The aluminum reflector offers a light-weight and rugged mechanical structure. The antenna body is treated with a chem film conversion coating for corrosion resistance. A corrugated scalar feed horn is used to provide optimal feed efficiency, low side lobes, high cross-pol rejection, and uniform illumination. The antenna port is a Ø 0.110” circular waveguide with UG-387/U-M anti-cocking flange that can support both linear and circular polarized waveforms. Other port configurations, such as a WR-10 or WR-12 waveguide port, are available under different model numbers.
