A new MIMO slot antenna is proposed in this paper, the proposed antenna consists of tuning stub with certain dimensions in the top layer of the FR-4 dielectric substrate to increase the matching between the feed line and slot in the ground plane, this antenna feeds with 50-ohm characteristic impedance microstrip feed line. The dimensions of the proposed antenna are (50×50×1.6) mm2, the FR-4 epoxy substrate has a relative dielectric constant of ɛr=4.3, the tangent loss of tan (δ) =0.025. A bandwidth of 9.083 GHz (25.917–35) GHz and gain (6.33) dBi compatible with 5G applications are achieved with this antenna. To get the desired gain and bandwidth, several slots are etched on the ground, Using CST tools, the simulation results are collected. And the proposed antenna is manufactured in the Ministry of Science and Technology's- Electronic Manufacturing Center, a reasonable agreement is reached between simulation and measured performance.
