This article outlines the development of a compact MIMO antenna with two ports crafted for millimeter-wave band operations, specifically tailored to support fifth-generation (5G) wireless applications. The suggested antenna is constructed on a Rogers RT/duroid 5880 substrate, measuring${12} \times {6}\times {0.508} \text{mm}{3}$. The proposed antenna has a slotted ground on the bottom and two Fractal-shaped radiating elements inspired by the Cantor Set pattern, positioned atop the dielectric material. The suggested antenna covers the millimeter-wave spectrum utilized in 5G, showcasing a wide bandwidth extending from 26.6 GHz to 29.08 GHz and 38.5 to 39.2 GHz. The antenna attains a maximum gain of 7.64 dBi, robust isolation exceeding 26 dB and demonstrates exceptional diversity performance, with an envelope correlation coefficient (ECC) below 0.003 and a diversity gain (DG) surpassing 10 dB. The obtained results Confirm the validity of the designed MIMO antenna's robustness and make it a viable option for 5G wireless equipment.
