K band

 
(′kā ′band)

(communications) A band of radio frequencies extending from 10,900 to 36,000 megahertz, corresponding to wavelengths of 2.75 to 0.834 centimeters.
(solid-state physics) An optical absorption band which appears together with an F-band and has a lower intensity and shorter wavelength than the latter.

NATO K band

The NATO K band is defined as a frequency band between 20 and 40 GHz (7.5–15 mm).

IEEE K band

The IEEE K band is a portion of the electromagnetic spectrum in the microwave range of frequencies ranging between 18 and 27 GHz. K band between 18 and 26.5 GHz is absorbed easily by water vapor (H2O resonance peak at 22.24 GHz, 1.35 cm).

Subdivisions

The IEEE K band is conventionally divided into three sub-bands:

  • Ka band: K-above band, 26.5–40 GHz, mainly used for radar and experimental communications.
  • K-band 18-27 GHz
  • Ku band: K-under band, 12–18 GHz, mainly used for satellite communications, terrestrial microwave communications, and radar, especially police traffic-speed detectors.

Infrared astronomy

Atmospheric windows in the infrared. The K band is the transmission window centred on 2.2 microns

In infrared astronomy, the K band refers to an atmospheric transmission window centred on 2.2 microns (in the near-infrared).

Name

The designation "K-band" stems from the German word "kurz" meaning short.[1]
