Performance Analysis of Millimetre Wave Antenna Arrays for 5G Cellular Applications
2021
The new technologies under research and development in the current scenario of mobile broadband have been categorically focused on the next generation of spectrum specifications, i.e. 5G. The new generation has been targeting the use of spectrum of 28 GHz and above. The paper has been designed to discuss some of the technologies which can be used in order to layout the foundation for 5G standard. The paper discusses about the concept of colossal MIMO which uses antenna arrays and large beam formation technology in order to state the high amount of data rate. The use of millimetre wave communication has been found to be a promising technology for the incorporation in the future of 5G cellular network which would be able to provide a very large data rate for mobile and cellular devices. Millimetre wave or mmWave communication process is a new and promising protocol for the implementation in 5G network due to its ability to provide a wide range of bandwidth. In order to compensate for the high attenuation and absorption of signals of the mmWave channel, the use of MIMO system has been introduced. However, the channel estimation is a challenge in such a system due to the higher channel complexity and the provision of limited coherence time.
