This article focuses on metamaterial inspired UWB-MIMO fractal antenna. Antenna loaded with the metamaterial structure achieved an impedance bandwidth of 5.8–15 GHz (98.63%). Mutual coupling between the two radiating elements is obtained to be less than − 25 dB. The patterns of radiation are stable over the operating range and a peak gain of 6.2 dBi is obtained at 14 GHz. Throughout the operating range, the radiation efficiency is > 88%. The obtained Envelope correlation coefficient-ECC (< 0.07), Mean effective gain-MEG (< 3 dB), Total active reflection coefficient-TARC (< − 10 dB) and Diversity gain-DG (> 9.98) proved that the desired antenna has a good diversity performance. The measured and simulated results are well adjusted, so that the antenna can be used for ultra-wide band applications. Simulation is conducted using HFSS simulation tool and printed on a 30 × 30 × 1.6 mm3 FR4 material.
