Compact, Wide-band, Dual linear Ku-band CATF feed for radiated mode characterization of multi-beam spacecraft

A Compact, wide band, dual linear CATF feed with two corrugations in Ku-band (10–15 GHz) is designed for performing radiated mode payload characterization of multibeam spacecraft in Compact Antenna Test Facility (CATF). The design of Ortho-mode transducer (OMT) and radiating aperture which constitutes CATF feed is described. Simulated results are presented in this paper.
