K-band K-bandThe band of electromagnetic radiation operating in the frequency range of 20 to 40 GHz, corresponding to a wavelength of 0.59 to 0.30 in (1.5–0.75 cm). Prior to 1962, K-band's operating frequencies ranged from 18 to 27 GHz, corresponding to a wavelength of 0.62 to 0.40 in (1.6–1.1 cm). |
