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, 27–40 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 radars, especially police traffic-speed radars.

Infrared astronomy K band

Infrared astronomers refer to the infrared region around 2.2 micrometres wavelength (136 THz) as K-band.
