- The correct title of this article is Ka band. It features superscript or subscript characters that are substituted or omitted because of technical limitations.
The Ka band (Pronounced: "Kay-Ay Band", Kurtz-above band) is a portion of the K band of the microwave band of the electromagnetic spectrum. Ka band roughly ranges from 18 to 40 GHz. The 20/30 GHz band is used in communications satellites, downlink 18.3–18.8 GHz and 19.7–20.2 GHz, and high-resolution, close-range targeting radars aboard military airplanes. The term “Ka band” is frequently used to refer to the recommended operating frequencies of WR-28 rectangular waveguide, which is 26.5 to 40.0 GHz.
