text: Antennas of this sort are preferred over the parabolic reflector for airborne applications (see the photograph), in land-based air-surveillance radars requiring multiple beams (as in the so-called 3D radars, which measure elevation angle in addition to azimuth and range), and in applications that require ultralow antenna sidelobe radiation.
