A type of antenna that combines a horn with a parabolic reflector is known as a Hogg-horn, or horn-reflector antenna, invented by Alfred C. Beck and Harald T. Friis in 1941 and further developed by David C. Hogg at Bell labs in 1961. It is also referred to as the "sugar scoop" due to its characteristic shape. It consists of a horn antenna with a reflector mounted in the mouth of the horn at a 45 degree … Webb10 aug. 2011 · Single feed per beam antennas are the current state of the art for multiple spot beam antennas. Each beam is created by a single horn. To avoid holes in the …
