Satellite Frequency Bands

Radio Spectrum: part of electromagnetic spectrum, frequencies from 30Hz to 300GHz; used mostly in telecommunication—whose generation and interefernece governed by International Telecommuniation Union (ITU) formed in 17 May 1865.

* Frequency Bands in the microwave range are noted with letters, which started around world war II

* microwave range: electromagnetic radiation ranging from one metre to one mm 300MHz to 300GHz,

* Radar: detection system using radio waves to detect range, angle, and velocity of objects (Radio Detection And Ranging)

* widely used standard is by IEEE radar bands

L Band (1 to 2 GHz, 15 to 30 cm λ): for clear turbulence studies, 

S Band (2 to 4 GHz, 5 to 15 cm λ): weather observation, for space communications with space shuttle

C Band (4 to 8 GHz, 3.75 to 5cm λ): TV stations, less power compared to S band

X Band (8 to 12 GHz, 2.5 cm to 3.75 cm λ): sensitive, for study of clouds, used in airplanes, airplanes, radar applications: continuous wave, pulsed, single polarization, dual polarization, synthetic aperture radar, phased arrays

Ku Band (12 to 18 GHz,  1.6 cm to 2.5 cm λ) ~ Kurtz under

K Band (18 to 26 GHz, 1.2 to 1.6cm λ): more sensitive ~Kurtz (German for Short)

Ka Band (26 to 40 GHz, 750mm to 1.6cm λ) ~ Kurtz above

V band (40 to 75 GHz, 40 mm to 750 mm λ)

W Band (75 to 111 GHz, 28mm to 40mm λ)

(>111 GHz) millimeter wave
