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.
