K Band Frequency Values | K Band Frequency Advantages,Applications
This page mentions K Band Frequency Values, K Band Frequency Applications and advantages of K Band frequency.
| Frequency Band Designation | Frequency Range | Wavelength |
|---|---|---|
| K Band | 18 to 27 GHz | 1.7 to 1.1 cm |
The K band frequency lies between Ku Band and Ka Band as shown in the figure-1 below. As mentioned in the table, it lies from 18 GHz to 27 GHz in the frequency spectrum with wavelengths between 1.1 centimeters to 1.7 centimeters.
K Band Frequency Advantages
Following are the advantages of K Band Frequency over other frequency bands.
➨As K band is in between Ku band Ka band. It supports throughput higher than Ku band and
lower than Ka band.
➨Its antenna size is smaller than Ku band and larger than Ka band.
➨K band is more susceptible to rain fading compare to Ku band and
less susceptible compare to Ka band.
The disadvantages of K band are as follows.
➨ K band frequencies have high atmospheric attenuation and hence
can not be used for long distance communication.
Hence it is used for short range communication.
K Band Frequency Applications
Following are the applications of K Band Frequency.
• K band in microwave domain is used for radar and satellite applications.
• K band in infrared domain is used for astronomical purpose.
