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 (ε_r) 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.

5G技术将比3G或4G彻底改变世界。5G意味着一个不仅人们而且所有事物也都连接在一起的世界。因此，无线技术的新版本为我们提供了许多优势，包括提高速度，减少磁阻，并为广泛的用户提供了更可靠的连接。本文提出了5G多输入多输出（MIMO）天线结构的设计。另外，正在使用插入进纸技术。MIMO是提高无线链路容量的手段。它提供更高的数据速率和可靠性，并且还可以在毫米波（mm-wave）频率下运行。贴片天线设计为以29 GHz的频率谐振。FR4环氧树脂，一种介电基材，用于建议的设计中，它具有介电常数（_εr）为4.4，基板的厚度（h）为1.6mm。在这项工作中，使用Ansys HFSS软件来设计和仿真MIMO天线系统。在所需的29 GHz频率下，多个天线以更好的S11，低VSWR，更高的性能和高带宽谐振。
