Ka Band Frequency Values | Ka Band Frequency Advantages,Applications
This page mentions Ka Band Frequency Values, Ka Band Frequency Applications and advantages of Ka Band frequency.
| Frequency Band Designation | Frequency Range | Wavelength |
|---|---|---|
| Ka Band | 27 to 40 GHz | 1.1 to 0.75 cm |
The Ka band frequencies lies above K Band as shown in the figure-1 below. As mentioned in the table, it lies from 27 GHz to 40 GHz in the frequency spectrum with wavelengths between 0.75 centimeters to 1.1 centimeters.
Ka Band Frequency Advantages
Following are the advantages of Ka Band Frequency over other frequency bands.
➨It allows high speed data communication.
➨It allows use of smaller dish antennas with diameters (0.9 meters).
➨Due to small antenna sizes, installation is cheaper and easier.
The disadvantages of Ka band are as follows.
➨It has significant signal attenuation due to rain fading.
➨Rain dissipates more energy at Ka band compare to Ku band.
➨It is not available for communication at all the places on the Earth.
Ka Band Frequency Applications
Following are the applications of Ka Band Frequency.
• Communication satellites
• Close range radars with high resolution
• Space telescope sends data collected to the Earth using
Ka band downlink frequencies for scientific analysis purpose.
• It is used in Inmarsat and will be available in Iridium Next series of satellites.
