Model SAR-2018-100-S2-DP is a full band, dual polarized, WR-10 horn antenna assembly that covers the frequency range of 75 to 110 GHz. The antenna features an integrated orthomode transducer (OMT) that provides high port isolation. The OMT enables the antenna to separate a circular or elliptical polarized waveform into two linear, orthogonal waveforms or vice versa. The dual polarized horn also supports either vertical or horizontal polarized waveguide forms with more than 30 dB cross polarization rejection. At center frequency, the horn antenna offers 20 dBi nominal gain and a typical half power beamwidth of 16 degrees on the E-plane and 18 degrees on the H-plane. The antenna exhibits 45 dB typical port isolation between the horizontal and vertical ports. The horizontal and vertical ports are WR-10 waveguides with UG-387/U-M flanges and 4-40 threaded holes.
