Diffraction radiation antennas are described, consisting of a dielectric waveguide and a diffraction grating. A wide variety of antennas models are presented, a number of them have been used in SHF and EHF radiosystems. Among them: antenna for 8 mm satellite radiometer, linear antennas for airborne side looking radars, antennas with cosecant-type radiation pattern, planar and linear scanning antennas meant for automobile radars, etc. New opportunities in antenna design are discussed in connection with technology and simulation progress.
