5G is expected to support enhanced Mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable low latency communication (uRLLC). 5G vision relies on a successful rollout of mmWave frequency technology. The millimeter (mm) Wave frequency band 6–100 GHz range provides more BW to achieve higher data rate but it supports 50–200 m short range only. 5G NR leverages the latest development in multi-input multi-output antennas (MIMO) and beam formation to minimize spectral efficiency and provide better quality of service for large number of users. Beam forming technology has been introduced in mmWave frequency band to compensate high path losses due to mmWave frequencies. Beam formation aims to generate different beams for different user equipment (UE) using an array of antennas elements at the base station (BS) to communicate between different users. The effective beams undergo minimum power loss and interferences and are aimed to direct towards the user equipment. In this paper, we have simulated different types of arrays and analyzed different beam contours that are generated from the arrays of antennas to transmit to the user equipment. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
