Design of MIMO Antenna System for 5G Indoor Wireless Terminals

Abstract

The proposed MIMO antenna system consists of six elements, its operating frequency band is 31.22-34.17 GHz and 31.79-33.37 GHz for −6dB and −10dB with resonant frequency of 32.56 GHz respectively. It covers the 5G proposed (additional) band, i.e., 31.8-33.4 GHz. 5G is much concerned with fast speeds in signal and data transmission as well as higher spectral efficiencies. The MIMO antenna system can improve the capacity and transmission rates in a communication system. The design with the help of simulation is quite important in visualization of the desired output and helps in achieving the required antenna results. Simulation results help in analysis of some parameters such as return loss and antenna isolation, to check the performance requirements of the designed system. According to the simulation results, the isolation is 17 dB between the antennas throughout the frequency band of 31.8-33.4 GHz, it will meet the requirements of future generation.
