SAG-1141743502-06-S1 is a 3.0” (Ø) D-band Gaussian antenna that operates from 110 to 170 GHz. The Gaussian antenna delivers a 35 dBi nominal gain and 2.0-degree half power beamwidth. The antenna supports linear waveforms and employs a corrugated feed horn to offer excellent aperture efficiency, high cross polarization rejection, and low sidelobe levels. This model is equipped with a standard WR-06 waveguide and UG-387/U-M anti-cocking flange as its input port. By removing the mode transition, Eravant model number SWT-06082-SB, the input port becomes a 0.082” diameter circular waveguide, which can support both linear and circular polarized waveforms.
