The Ka band (Pronounced: "Kay-A Band") covers the frequencies of 26.5-40GHz[1]. The Ka band is part of the K band of the microwave band of the electromagnetic spectrum. This symbol refers to "K-above" — in other words, the band directly above the K-band. The so-called 30/20 GHz band is used in communications satellites, uplink in either the 27.5 GHz and 31 GHz bands[2], and high-resolution, close-range targeting radars aboard military airplanes. Some frequencies in this radio band are used for vehicle speed detection by law enforcement[3]. Kepler Mission uses this frequency range to downlink the scientific data collected by the space telescope.
The designation "Ka-band" is from Kurz-above, which stems from the German word "kurz" meaning short.[4]
