Abstract
Overmoded corrugated guide feedst used for high efficiency illumination of reflector antennas, suffer from an inherently restricted bandwidth of operation because of the dispersion in phase velocities of the modes. Experimental results, obtained with a 2-hybrid-mode feed, show that the dispersion can be compensated for by the frequency dependent mode generation characteristics of the input mode transducer and extremely large bandwidths of operation can be realised.
