This research delves into the realm of antenna engineering, with a specific focus on examining the performance of 4x4 MIMO antennas with and without integration of split ring resonator metamaterial structure. The objective is to comprehend the influence of split ring resonator metamaterials on antenna characteristics within the 6 GHz frequency range. Employing CST Studio Suite software, comprehensive simulations are conducted to evaluate various parameters including gain, directivity, radiation efficiency, S-parameters, power distribution, VSWR, and total efficiency. In the frequency band up to 6GHz, observed gain values were 24.62dB without split ring resonator metamaterial integration and ranging from 6dB to 27dB with integration. Through a systematic comparison, the study aims to delineate the precise effects of split ring resonator metamaterials on antenna performance, thereby offering valuable insights into their potential for enhancing MIMO antenna systems.

“…To reduce this mutual coupling, various mutual coupling (MC) reduction or decoupling, or isolation enhancement techniques were introduced in the literature. They are neutralization line (NL) [2], decoupling network (DN) [3][4][5][6], metasurface, metamaterial (MTM) [7], electronic band gap (EBG) [8,9], frequency selective surface (FSS), photonic band gap (PBG), optically transparent structures [10], split ring resonator (SRR), complementary split ring resonator (CSRR) [11,12], dielectric resonator antenna (DRA), ground plane modification (GPM), defected ground structure (DGS) [13,14], slots [15][16][17][18], band notching techniques implementation, parasitic elements, metal strips, shorting pins, insertion of stubs [19][20][21], frequency reconfigurable [22,23], implementing PIN diodes, microstrip open loop resonator (MOLR), quasi self complementary antenna (QSCA) [24], inter element spacing [25][26][27][28][29], insertion of slits, fractal structures, modified substrates, locating antennas on different substrate layers, etc. These techniques improve impedance matching, enhance gain, efficiency, and increase the complexity of antenna design.…”

This present article reports a high isolation four-port Wrench shaped compact UWB MIMO antenna with a novel decoupling network in the ground plane, and its step-by-step evolution is presented for 3.1-10.6 GHz. The proposed four-port MIMO antenna is fabricated on an FR4 substrate of size 44 × 44 mm 2 (0.342λ 0 × 0.342λ 0 ), where λ 0 is a free space wavelength at 2.33 GHz, with 7 mm edgeto-edge spacing between the radiating elements. It consists of four orthogonal symmetrically placed identical radiating elements each of which has a Wrench-shaped circular patch with a rectangular slot cut in the partial ground. The performance characteristics of this MIMO antenna are reflection coefficients S 11 ≤ −10 dB in the range from 2.33 GHz to 11.7 GHz, mutual coupling coefficients S 21 ≤ −28.24 dB, and S 31 ≤ −22.35 dB. The maximum peak gain is 5.15 dBi at 9.2 GHz, and minimum is 1.27 dBi at 3.1 GHz. The maximum efficiency is 98% at 4.66 GHz, and the minimum is 93% at 6 GHz. The diversity parameters of proposed four-port MIMO antenna are reported as ECC ≤ 0.2, DG ≤ 10, TARC ≤ −10 dB, the ratio of MEG between any two elements is near unity, and CCL < 0.38 bits/s/Hz in the band of interest. The design is fabricated and measured. The measured and simulated results are in good agreement and are within the permissible limits.

The 4-Port multiband operated MIMO antenna operating at 4GHz, 6GHz and 9GHz is proposed to target the 5G and P2P communication applications. The electrical size of the 4-Port antenna structure is 0.8λ x 0.48λ. The unique shape of a single radiating patch element is identified by engraving a circular shape patch element and modifying the shape of the feedline. The optimisation in terms of return loss was achieved based on the defected ground structure and changing radius of different elements of the patch structure. The 2-Port and 4-Port MIMO antenna structures are designed using the FR4 substrate and their return loss is compared and examined. The proposed design provides a minimum return loss of -22dB, peak bandwidth of 2.25GHz, peak gain of 4.67dB, and normalised directivity of 1870. Different MIMO diversity parameters are analysed. The proposed design provides an envelope correlation coefficient of 0.01, Diversity gain near 10dB, mean effective gain of almost zero, channel capacity loss of almost zero and Mean effective gain within the acceptable range. The overall Performance of the Proposed Design is compared with other 4-Port design structures and it represents healthy gain, multiple band response and proper diversity parameters making it suitable for the 5G and P2P communication applications.
