What frequency range does the Ka band cover?

The Ka band is part of the microwave band of the electromagnetic spectrum and covers the frequency range of 27 to 40 GHz. This band is significant in various applications, including satellite communication, radar systems, and some types of wireless networks. One of its key advantages is the ability to provide high data rates and bandwidth compared to lower frequency bands. The Ka band is particularly useful for applications that require high-resolution signals, which makes it integral in radar meteorology for observing precipitation, wind profiles, and other atmospheric phenomena.

In contrast to the other frequency ranges mentioned, options that describe lower frequency bands do not align with the characteristics of the Ka band. The descriptions of 2-4 GHz, 8-12 GHz, and 40-50 GHz refer to different segments within the microwave spectrum, with 40-50 GHz being adjacent but not representing the Ka band itself accurately. Thus, 27-40 GHz is the correct representation of the Ka band frequency range.
