Model SAR-1532-224-S2-DP is a full band, dual polarized, WR-22 horn antenna assembly that covers the frequency range of 33 to 50 GHz. The antenna features an integrated orthomode transducer (OMT) that provides high port isolation and cross-polarization cancellation. 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 15 dBi nominal gain and a typical half power beamwidth of 28 degrees on the E-plane and 33 degrees on the H-plane, and -15 dB sidelobe levels, respectively. The antenna exhibits 45 dB typical port isolation between the horizontal and vertical ports. The horizontal and vertical ports are WR-22 waveguides with UG-383/U flanges and 4-40 threaded holes.
