E-Band Gaussian Optics Antenna, 71 to 86 GHz, 40 dBi Gain, 6”
Description:
Model SAG-7138634002-110-S1 is a 6” E-Band Gaussianantenna that operates from 71 to 86 GHz. The Gaussianantenna delivers a 40 dBi nominal gain and 1.8-degree
typical half power beamwidth at center frequency. The
antenna supports linear and circular polarized waveforms
and employs a corrugated feed horn to offer excellent
aperture efficiency, high cross polarization rejections, andlow sidelobe levels. This model is equipped with a Ø 0.110”
circular waveguide with UG-387/U-M flange as its input port.
By adding a mode transition, model SWT-12110-SB, theinput port becomes a standard WR-12 rectangular waveguide, which can only support linear polarizedwaveforms.

All antenna pattern and gain data presented is simulated. Actual data may vary, slightly.
Return loss data was presented using a limited sample lot. Actual data may vary unit to unit.
Eravant reserves the right to change the information presented without notice.
The operation frequency of the antenna can be extended to a wider range with small
performance degradation at the edges of the band.

Caution:•Foreign objects in the waveguide will affect device performance and may damage the antenna.
