Abstract: A multiple input–multiple output (MIMO) antenna is a necessary part of the field of wireless communication systems. Further, the meta-material plays a major part in reducing coupling between antennas. Hence, in this work, a meta-material-based 4-port MIMO antenna is designed for the UWB application using three band operations such as WiMAX (3.2–3.7 GHz), WLAN (4.1–6 GHz) and X-bands (8–12.1 GHz). In this research, the MIMO antenna is designed with complementary-split ring resonators (C-SRR) to improve the bandwidth of antenna elements with defected ground structure (DGS). Further, the metaheuristic algorithm honey badger optimization (HBO) is used for optimizing the antenna dimensions. The proposed design is simulated in the HFSS simulation platform on an FR-4 substrate with dimensions of 38 × 38 × 1.6mm3. The gap between the elements of an antenna is 0.1λ0. The radiation efficiency attained by the proposed structure is 93.7% for the overall operating range. Further, the MIMO system is a compact size and achieved a better envelope correlation coefficient (ECC < 0.01), total active reflection coefficient (TARC < −10dB), diversity gain (DG < 9.9dB), channel capacity loss (CCL < 0.4) and mean effective gain (MEG < 3dB) at 3.7 GHz. Finally, it is concluded that the proposed meta-material-based MIMO antenna is the appropriate selection for the UWB applications.
