This page explores Ku Band frequency, including its values, applications, and advantages.

Frequency Band DesignationFrequency RangeWavelength
Ku Band12 to 18 GHz2.5 to 1.7 cm

The Ku band frequency sits between the X Band and K Band in the electromagnetic spectrum, as illustrated in Figure 1 below.

As shown in the table, its frequencies span from 12 GHz to 18 GHz, corresponding to wavelengths between 1.7 centimeters and 2.5 centimeters.

Ku Band Frequency: Advantages and Disadvantages

Here’s a look at the advantages of Ku Band frequency over other frequency bands:

  • Smaller Antennas: It allows for the use of smaller dish antennas in VSAT applications. This leads to cheaper and easier installation.
  • Higher Transponder Power: In certain scenarios, Ku band offers higher satellite transponder power.
  • Reduced Terrestrial Interference: Ku band experiences less interference from terrestrial sources.

However, Ku band also has some disadvantages:

  • Susceptibility to Rain Fade: Ku band signals are prone to rain fading, where heavy rain can significantly attenuate the signal.
  • Narrow Beam Coverage: Due to its narrow beam, Ku band can cover a smaller area on Earth.

Ku Band Frequency Applications

Ku Band Frequency

Ku Band frequency has a variety of uses, including:

  • Ku Band VSAT: Ku band VSAT systems utilize uplink frequencies from 14 to 14.5 GHz and downlink frequencies from 10.95 GHz to 11.7 GHz.
  • Fixed Satellite Broadcast Services: It’s employed for fixed satellite broadcasting.
  • NASA Space Shuttle Communication: Ku band is used for communication with space shuttles via NASA’s tracking data relay satellites.
  • International Space Station Communication: NASA uses Ku band for communication with the International Space Station.
  • VSAT Comparison: Refer to the difference between Ku Band and C Band for VSAT applications.
