![]() Apart from bandwidth, these frequency bands are less congested, making them significant in satellite and radar communications. ![]() They are designated by the Institute of Electrical and Electronics Engineers (IEEE). X to Ka frequency bands (previously called radar frequency bands) are the set of frequencies used in radar, terrestrial, and satellite applications. ![]() In complex satellite missions, the limitations of signal processing techniques and modulation schemes led to the use of X band to Ka-band frequencies. However, this strategy has some upper limits beyond which the bandwidth of higher frequencies needs to be accessed to provide sufficient transmission capacity. The method of applying advanced modulation techniques helps in achieving high point-to-point data rates, increased sharing of the bandwidth, and increased reuse of frequencies. To meet bandwidth demands, one method is to employ advanced modulation techniques to increase spectral utilization efficiency. With the increase in wireless networking systems, there is an ever-growing demand for bandwidth to increase transmission capacity and data transfer rates. The Ka-band frequency is at the top of the commercially available frequency spectrum, which is used in high throughput satellite (HTS) services. The Ka-band frequency showcases high potential in supporting military forces, radars, aircraft, radio communications, and satellite communications. The Ka-band consists of frequencies in the range 27 GHz to 40 GHz and a wavelength between 1.1 to 0.75 centimeters. ![]()
