The Probe-fed cheese antenna is part of a family of antennas often called pillbox antennas. Pillboxes are sectoral reflector antennas that are often used in search-radar applications as they can produce narrow fan-beams and handle high power.

The Probe-fed cheese can be considered to be a sectoral part of a line-fed cylindrical reflector. These types of antennas were popular in WW2 radar systems (like the royal navy type 271 radar system and the stacked transmit/receive antenna from a 1941 radar shown below).
