In this paper, two-port Electric-Inductive-Interdigital Capacitor (ELIDC) metamaterial Array Multi-Input-Multi-Output (MIMO) antenna is designed with enhanced gain, bandwidth, and isolation for frequency bands 5.125GHz – 5.825GHz and 5.925GHz-7.125GHz for the Wi-Fi 5 and 6E applications. The proposed MIMO antenna comprises corporate fed ELIDC metamaterial arrays, which are fed in two opposite directions. The ground plane consists of a Defected Ground Structure (DGS) for enhancement of bandwidth. A novel four split-ring resonator (SRR) array is embedded between two radiating elements of the DGS ground plane to increase the isolation. To validate the blocking of electromagnetic propagation between antenna elements, negative permeability in the desired frequency is extracted using the Nicolson-Ross-Weir (NRW) method. The isolation is enhanced to -30dB by incorporating the SRR array. The proposed ELIDC array MIMO antenna is fabricated and measured S parameters, gain and radiation pattern are giving good consistency between simulated results. The Envelope Correlation Coefficient (ECC), Diversity Gain (DG), and Total Active Reflection Coefficient (TARC) of the diversity performance show that the proposed ELIDC array MIMO antenna can be used in MIMO Tx/Rx systems.
