Özet
This study proposes an optimized MIMO antenna array design for 5G mm-wave communication systems that operates in the 38 GHz band. The design consists of two antenna arrays, each with four evenly spaced elements. The two arrays are assembled with a 90-degree shift, which provides improved performance in terms of gain, efficiency, and beamforming. The substrate is a Rogers RT5880 with a thickness of 0.254 mm and dielectric constants of 2.2 and a loss tangent of 0.0009, respectively. The proposed work combines the most desirable characteristics, including unique design, high gain, efficiency and wide operation of bandwidth. The proposed array antenna design offers a high efficiency up to 86.56% and high average gain up to 12.35 dBi for port-1 and port-2, resulting in attractive performance. The achievable bandwidth in the 38 GHz frequency band (37.5 - 38.4 GHz) is up to 927 MHz for port-1 and port-2. The return loss of our design is up to - 23.28 dB, which is still considered low loss for 38 GHz. The results obtained show that the antenna is a viable candidate for 5G applications at 38 GHz.
