Copyright © 2022 by Eravant

Description:

Model SAP-08-R2 is an F-band probe antenna that

operates from 90 GHz to 140 GHz. The antenna offers

6.5 dBi nominal gain and 115 degrees typical half power

beamwidth on the E-plane and 60 degrees typical half

power beamwidth on the H-plane. The antenna

supports linear polarized waveforms. The input of this

antenna is a WR-08 waveguide with UG-387/U-M Anti-

Cocking flange.
