SAG-1441544601-059-S1

Rev. 1.2

Description:
Model SAG-1441544601-059-S1 is a 6” D-Band Gaussianantenna that operates from 140 to 150 GHz. The Gaussianantenna delivers a 46 dBi nominal gain and 0.95 degree
half power beamwidth. The antenna supports both linear
and circular polarized waveforms and employs acorrugated feed horn to offer excellent aperture
efficiency, high cross polarization rejections, and low
sidelobe levels. This model is equipped with a 0.059”
diameter circular waveguide and UG-387/U-M anticocking flange as its input port. By adding a modetransition, Eravant model number SWT-06059-SB, the input port becomes a standard WR-06 waveguide,
which can support only linear polarized waveforms.
