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 … WebbThe parabolic reflector transforms an incoming plane wavetravelling along the axis into a spherical waveconverging toward the focus. Conversely, a spherical wave generated by a point sourceplaced in the focusis reflected into a plane wave propagating as a collimated beamalong the axis.
