G-Band Gaussian Optics Antenna

45 dBi Gain, 140 to 220 GHz, 6" Diameter Lens, 0.059" Dia Circular Waveguide
SAG-1442244501-059-S1 is a 6.0” (Ø) G-band Gaussian antenna that operates from 140 to 220 GHz. The Gaussian antenna delivers a 45 dBi nominal gain and 1 degree half power beamwidth. The antenna supports linear and circular polarized 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 0.059” diameter circular waveguide and UG-387/U-M anti-cocking flange as its input port. By adding a mode transition, Eravant model number SWT-05059-SB, the input port becomes a standard WR-05 waveguide, which can only support linear polarized waveforms.
