abstract={This paper explores the impact of mutual coupling on the performance of MIMO systems, particularly in 5G microstrip antennas. Through simulations, we investigate the coupling effect in a proposed Microstrip Patch Antenna (MPA) design. A single-element MPA and a 4-element antenna array are designed to analyze mutual coupling and improve isolation by introducing slots, thereby increasing the data rate. The slotted single microstrip antenna achieves a 175% bandwidth improvement, covering 27.6 GHz to 29.7 GHz at a center frequency of 28 GHz. The results show that the 4-element slotted microstrip MIMO antenna system reduces mutual coupling to -16.675 dB, outperforming the not slotted design (-14.4 dB). This work aims to design a single-band 4-element MIMO microstrip antenna for 5G systems, enhancing bandwidth, reducing mutual coupling, and achieving high data rates, polarization, bandwidth (>1 GHz), and realized gain at 28 GHz.},
