The Ka band (Pronounced: "Kay-A Band") covers the frequencies of 26.5–40 GHz. 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,<ref>http://www.tech-faq.com/ka-band.shtml</ref> 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. 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.
