SAR-1340-12-S2

Rev 1.4

Description:
Model SAR-1340-12-S2 is an E-band rectangularhorn antenna that operates from 60 GHz to 90 GHz.
The antenna offers 13 dBi nominal gain and atypical half power beamwidth of 39 degrees on Eplane and 41 degrees on H-plane, respectively. Theantenna supports linear polarized waveforms. The
input of this antenna is a WR-12 waveguide with
UG-387/U anti-cocking flange.
