Abstract : EW ;F30602-72-C-0171RADCTR-73-71(*antenna feeds, tracking), waveguides, reflectors, antenna radiation patterns, standing wave ratios, bandwidth, radiofrequency interferenceEquations were developed for the hybrid mode fields which exist in a square corrugated waveguide. Propagation constants were obtained for the various modes of interest. A hybrid-mode tracking feed horn was designed and tested, and its characteristics compared with those obtained analytically. Evaluation was based on radiation characteristics, VSWR, bandwidth, and channel isolation. Emphasis was placed in two areas: first, to show the radiation characteristics the feed horn would have if working perfectly and second, to obtain a good understanding of the feed system to point out the areas requiring further effort.
