Abstract
Beamforming is the process of directing the beam towards the desired direction while suppressing the signals from other directions. Multiple Input Multiple Output systems along with beamforming has a major influence on the next-generation wireless communication system. Techniques like beamforming is increasing its use in cellular telecommunication and particularly in 5G. The work carried out is to reduce the beam width of the main lobe of the beam pattern. Reducing the beam-width ensures that more signals can be radiated in the serving area. By increasing the separation between array elements, the lobe width decreases or the array directivity improves. Reduction of side lobe level reduces noise and interference with other signals so that the receiver receives good quality signal. Also, the main lobe beam is made to reach the user equipment. The beam width of the main lobe becomes narrower with increase in the number of antennas of the uniform linear array.
