“…Moreover, parametric analysis empowers designers to evaluate the antenna's capability to withstand various environmental conditions and achieve an optimal trade-off between cost, size, and performance. Fundamentally, parametric analysis functions as a potent instrument for customizing antennas to fulfil the distinct demands of various applications, thereby augmenting their operational capabilities and guaranteeing peak performance [46].…”

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.

“…As a result, multiple individuals can connect to the network simultaneously. For the proper functioning of a multiple input multiple output (MIMO) antenna system, certain conditions must be met, including isolation between the antenna elements, diversity gain, envelope correlation coefficient, and mean effective gain [6,7]. Nearly every single one of the designs for MIMO antennas that have been published in the relevant body of scholarly research only barely meets the minimum criteria of mutual coupling, which is very close to being an acceptable value.…”

This article describes a fractal-based MIMO antenna for 5G mm-wave mobile applications with micro-strip feeding. The proposed structure is a fractal-based spherical configuration that incorporates spherical slots of different iterations on the patch, as well as rectangular slots on the ground plane. These additions are meant to reduce patch isolation. The two-element MIMO antenna has closely spaced antenna elements that resonate at multiple frequencies, 9.5 GHz, 11.1 GHz, 13.4 GHz, 15.8 GHz, 21.1 GHz, and 26.6 GHz, in the frequency range of 8 to 28 GHz. The antenna’s broadest operational frequency range spans from 17.7 GHz to 28 GHz, encompassing a bandwidth of 10,300 MHz. Consequently, it is well-suited for utilization within the millimeter wave (mm wave) application, specifically for the 5G new radio frequency band n258, and partially covers some other bands X (8.9–9.9 GHz, 10.4–11.4 GHz), and Ku (13.1–13.7 GHz, 15.4–16.2 GHz). All the resonating bands have isolation levels below the acceptable range of (|S12| > −16 dB). The proposed antenna utilizes a FR4 material with dimension of 28.22 mm × 44 mm. An investigation is conducted to analyze the effectiveness of parameters of the antenna, including radiation pattern, surface current distributions and S parameters. Furthermore, an examination and assessment are conducted on the efficacy of the diversity system inside the multiple input multiple output (MIMO) framework. This evaluation encompasses the analysis of key performance metrics such as the envelope correlation coefficient (ECC), diversity gain (DG), and mean effective gain (MEG). All antenna characteristics are determined to be within a suitable range for this suggested MIMO arrangement. The antenna design underwent experimental validation and the simulated outcomes were subsequently verified.

“…Various hybrid methods exist, such as the use of EBG and DGS together [ 34 ], L-shaped stubs, defective ground, and chip resistors used together [ 35 ], the use of the DGS method on the ground plane and epsilon-and-mu-near-zero-based metasurface superstrate [ 36 ], and the use of slot and parasitic element structures [ 37 ]. Moreover, various techniques have been employed to enhance the isolation levels in MIMO antennas by mitigating mutual coupling effects, such as the decoupling network [ 38 ], the integration of vias [ 39 ], a zigzag-shaped slotted structure in the ground plane [ 40 ], a partially reflecting surface [ 41 ], a partial ground surface [ 42 ], a partial ground surface combined with metasurface [ 43 ], a slot in the ground plane [ 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 ], decoupling branches [ 52 ], and a stub in the ground plane [ 53 ]. The techniques for enhancing isolation used in prior research are known to be expensive and involve several processing steps.…”

This paper presents the design and realization of a simple and low-profile, four-port multiple-input-multiple-output (MIMO) antenna operating in a mm-wave band supporting 5G communication technologies. As part of the design methodology, the initial stage involved the development of a conventional monopole patch antenna optimized for operation at 26 GHz, which was matched to a 50 Ω stepped feed line. Afterward, a square-shaped defected ground structure (DGS) with semi-circle slots on the edges was placed on the ground to improve the isolation, and the circular and rectangular slots were incorporated as DGSs to optimize the antenna impedance bandwidth. Etching semi-circular-shaped slots on the ground plane achieved more than 34.2 dB isolation in the 26 GHz operating band. In addition, an arrangement of four symmetrical radiating elements was positioned orthogonally to minimize the antenna’s physical size and improve the isolation. The proposed MIMO antenna’s overall dimension was 25 × 25 mm2, which was printed on a Rogers 5880 substrate at a width of 0.787 mm and εr = 2.2. The proposed antenna covered the 5G mm-wave band with a 10 dB bandwidth ranging from 25.28–28.02 GHz, whereas the maximum gain attained for the proposed structure was 8.72 dBi. Additionally, the implementation of these slots effectively mitigated mutual coupling, resulting in reduced envelope correlation coefficient (ECC) values. Furthermore, other MIMO performance metrics, including channel capacity loss (CCL), mean effective gain (MEG), and diversity gain (DG), were analyzed for the proposed structure. The obtained results indicate its suitability for various usage areas, such as smart devices, mobile phones, and sensors in 5G applications.
