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.

*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 K band
Infrared astronomers refer to the infrared region around 2.2 micrometres wavelength (136 THz) as "K-band".
The designation "K-band" stems from the German word "kurz" meaning "short". [http://www.itwissen.info/definition/lexikon/K-Band-K-band.html (german)]
