Abstract
This study provides a novel 4 Port “MIMO antenna” design for “5G mm wave” implementation. This designed antenna operates in mm-wave band and adheres to the 5th generation's specifications. The antenna is described from two perspectives. The array elements appear to be arranged in a rectangular shape from the top view, however the bottom view, which is the view on the substrate, is composed of rectangular and ring-shaped slots to improve the antenna's radiating properties. In general, the study covers all aspects of the MIMO antenna design, including antenna methodology, simulation results and among other things. The antenna equipment supports impending mm-wave 5G applications by operating in the 25.5-29.6 GHz frequency spectrum. Furthermore, the operational frequency band achieves a peak gain of 8.3dBi. Once again, polarization diversity is used between adjacent radiators to achieve great isolation between antenna parts, resulting in low envelope correlation Coefficient.
Keywords: MIMO, Microstrip Antenna, Antenna array, Defected Ground Structure (DGS), 5G mm-wave.
