Over the last twenty years Corrugated horns have become widely used as feeds for microwave reflector antennas because of their high efficiency, good pattern symmetry and low cross-polarisation. They are increasingly used in antennas for satellite communications, radar, microwave point to point communications and radio astronomy.The authors draw on more than fifteen years experience to write the first book to appear devoted to the theory and design of corrugated horns and scalar feeds.The book explains why hybrid mode feeds are ideal feeds for reflectors. The propagation and radiation behaviour of cylindrical corrugated waveguides, narrow flare angle conical corrugated horns and wide flare angle corrugated horns are described. Factors relevant to the practical design of corrugated horns are discussed. Other topics treated include the measurement of corrugated horns.
