Copyright © 2023 by Eravant

Description:

Model SAP-04-R2 is a WR-04 probe antenna that operates

from 170 GHz to 260 GHz. The antenna offers 6.5 dBi

nominal gain and 115 degrees typical half power beamwidth

on the E-plane and 55 degrees typical half power

beamwidth on the H-plane. The antenna supports linear

polarized waveforms. The input of this antenna is a WR-04

waveguide with a UG-387/U-M anti-cocking flange.
