Abstract

The 5G technology will revolutionize the world more than 3G or 4G. 5G means a world where not only people but all the things are also connected. Thus, a new version of wireless technology gives us a lot of advantages which include a boost in speed, reduce reluctance, and provides a more reliable connection for a wide range of users. In this paper, the design of 5G Multiple Inputs and Multiple Outputs (MIMO) antenna structure is proposed. Also, an inset feeding technique is being used. MIMO is the means for improving the capacity of the radio link. It provides higher data rates and reliability which also operates at millimeter-wave (mm-wave) frequency. The patch antenna is designed to resonate at a 29 GHz frequency. The FR4 epoxy, a dielectric substrate is used in the proposed design which has a dielectric constant (εr) of 4.4 and thickness (h) of the substrate is 1.6 mm. In this work, Ansys HFSS software is used to design and simulate the MIMO antenna system. At a desired frequency of 29 GHz, the multiple antennas are resonated with better S11, low VSWR, higher performance, and high bandwidth.
