The Ka band ("kay-ay band") is a portion of the microwave part of the electromagnetic spectrum defined as frequencies in the range 26.5–40 gigahertz (GHz),i.e. wavelengths from slightly over one centimeter down to 7.5 millimeters. The band is called Ka, short for "K-above" because it is the upper part of the original NATO K band, which was split into three bands because of the presence of the atmospheric water vapor resonance peak at 22.24 GHz, (1.35 cm) which made the center unusable for long range transmission.

In satellite communications, the K band allows higher bandwidth communication. It is used in the Inmarsat I-5 system[6] and will be used in the Iridium Next satellite series, as well as the James Webb Space Telescope. The Ka band is more susceptible to rain attenuation than is the Ku band, which in turn is more susceptible than the C band.
