“…Therefore, one of the main concerns in UWB MIMO antenna development is how to improve cell-to-cell isolation. Creating decoupling structures [3], [4], cutting slits [5] loading metamaterials, decoupling frequency-selective surfaces [6], electromagnetic bandgap structures [7]- [9], neutralisation lines [10]- [13], and parasitic cell decoupling [14], as well as Indonesian J Elec Eng & Comp Sci ISSN: 2502-4752  erroneous grounding structures [15], [16] and polarisation diversity techniques [17]- [19], are typical methods to increase MIMO antenna isolation. The isolation between cells is effectively increased to more than 2 dB using two-port MIMO antenna [3] uses a "T"-shaped separation structure between cells, but bandwidth is only 2.33-6.71 GHz, and the size is too huge.…”

The method for creating a two-element multiple-input and multiple-output (MIMO) ultra-wideband hammer antenna is presented in this paper. It has been suggested to investigate characteristics of this ultra-wideband antenna design. Split-ring resonators (SRR), made of metamaterial, have enhanced performance of antenna in terms of multiplexing effectiveness, S parameters, radiation characteristics, envelope correlation coefficient, and diversity gain. Reduced weight and size of this antenna technology make it easier to integrate into a 5G and linked object receiver. Because the outputs from the previous designer to the target entity did not satisfy the standards, we thoroughly researched design attributes and made parametric changes to the design to reach the precise outcomes.

“…Researchers have adopted many techniques to improve the isolation between elements in MIMO antenna systems. These techniques include the loading of FSS (Frequency Selective Surface) sheets [15,16], absorbers [17], metamaterial [18][19][20][21][22], defective ground structures (DGS) [23][24][25][26], and decoupling structures [27][28][29][30][31]. The FSS sheet is kept below the antenna to bounce back the waves in order to upgrade the outcomes.…”

“…The FSS sheet is kept below the antenna to bounce back the waves in order to upgrade the outcomes. Due to the bounced-back radiation and antenna radiation, the overall performance is improved [16]. In the case of an absorber, an unwanted spectrum is eliminated to improve the function of the desired band.…”

This article presents an antenna with compact and simple geometry and a low profile. Roger RT6002, with a 10 mm × 10 mm dimension, is utilized to engineer this work, offering a wideband and high gain. The antenna structure contains a patch of circular-shaped stubs and a circular stub and slot. These insertions are performed to improve the impedance bandwidth of the antenna. The antenna is investigated, and the results are analyzed in the commercially accessible electromagnetic (EM) software tool High Frequency Structure Simulator (HFSS). Afterwards, a two-port multiple–input–multiple–output (MIMO) antenna is engineered by orthogonalizing the second element to the first element. The antenna offers good value for mutual coupling of less than −20 dB. The decoupling structure or parasitic patch is placed between two MIMO elements for more refined mutual coupling of the proposed MIMO antenna. The resultant antenna offers mutual coupling of less than −32 dB. Moreover, other MIMO parameters like envelop correlation coefficient (ECC), mean effective gain (MEG), diversity gain (DG), and channel capacity loss (CCL) are also studied to recommend antennas for future applications. The hardware model is fabricated and tested to validate the results, which resembles software-generated results. Moreover, the comparison of outcomes and other important parameters is performed using published work. The outcome of this proposed work is performed using already published work. The outcomes and comparison make the presented design the best option for future 5G devices.

The design of a 4 × 4 MIMO antenna for UWB communication systems is presented in this study. The single antenna element is comprised of a fractal circular ring structure backed by a modified partial ground plane having dimensions of 30 × 30 mm2. The single antenna element has a wide impedance bandwidth of 9.33 GHz and operates from 2.67 GHz to 12 GHz. Furthermore, the gain of a single antenna element increases as the frequency increases, with a peak realized gain and antenna efficiency of 5 dBi and >75%, respectively. For MIMO applications, a 4 × 4 array is designed and analyzed. The antenna elements are positioned in a plus-shaped configuration to provide pattern as well as polarization diversity. It is worth mentioning that good isolation characteristics are achieved without the utilization of any isolation enhancement network. The proposed MIMO antenna was fabricated and tested, and the results show that it provides UWB response from 2.77 GHz to over 12 GHz. The isolation between the antenna elements is more than 15 dB. Based on performance attributes, it can be said that the proposed design is suitable for UWB MIMO applications.
