This book is the first comprehensive treatment of microwave horns and feeds for reflector antennas for use in satellite and terrestrial communications, radar and radio astronomy. The feed for a reflector antenna is a crucial component because the performance of the reflector depends on a good feed to collect or radiate signals.The book presents the principles and applications of reflector and horn antennas with emphasis on the developments of the last decade. The background theory is included and the analytical techniques are explained. Extensive design data and numerous examples of practical horn and feed antennas are given.The book is a collaboration between four authors, bringing together an unrivalled knowledge of analytical techniques and experience in designing horns, feeds and reflector antennas. The book should be of value to both the research worker and the designer of practical feeds for reflector antennas.

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.
