“…This MIMO antenna operates at 2.2-12.3 GHz bandwidth with isolation of less than -16 dB, and the ECC value is below 0.3. Furthermore, the use of the defected ground plane [17], employing the decoupling configurations between the antenna components, and using various slots and stubs on the ground plane are two popular methods to increase the MIMO antenna isolation [18] and [19]. Also, other designs are presented in references [20] - [24], which have acceptable results.…”

“…The references mentioned above often follow two types of design. These antennas either have a planar structure like references [14] and [18][19][20], or they support a 3D configuration like references [15][16][17] and [21][22][23][24]. Planar antennas usually have lower gain and isolation and can often show good gain and performance at higher frequencies.…”

Compact Self-Isolated Four-Element MIMO Antenna for WLAN and ISM Bands Application

A compact self-isolated four-element MIMO antenna is introduced for use in ISM systems and WLAN applications in the 2.4 GHz frequency band. The proposed design consists of four printed dipoles so four integrated baluns are responsible for feeding these antennas. By choosing an appropriate arrangement of the elements next to each other and using the feature of self-isolated antennas, great isolation is achieved in the first step. Finally, by utilizing a printed decoupling component in the space between the dipoles, the value of the envelope correlation coefficient (ECC) parameter comes very close to zero for the MIMO antenna. The major part of the isolation in this design is the responsibility of the self-isolated technique, and adding the decoupling element at the last stage of the design is to complete the antenna isolation process. The fabricated prototype of the proposed MIMO antenna operating at 2.25-2.87 GHz frequency band reaches the measured port-to-port isolation of better than 19 dB, ECC of less than 0.0009, the peak gain of 8.6 dBi with total dimensions of 1.11λ0×1.11 λ0×0.34λ0. The numerical and experimental results approve the excellent MIMO performance for 2.4 GHz applications.INDEX TERMS self-isolated, MIMO antenna, WLAN, ISM

“…As a result of MIMO antennas, multipath interference fading has been eliminated, and their reliability has improved. The MIMO antenna is designed by designing radiation elements individually, then by putting these elements together in the next step [7]. Today, printed antennas have become more popular due to their light structure, cheapness, and ease of connection to other microwave components [8,9,10].…”

This study introduces a novel multi-objective optimization algorithm integrating Customized Mutated PSO (CM-PSO) and an innovative modified Genetic Algorithm (GA) using an unexplored merged chaotic map. The hybrid algorithm con- verges to desired results faster than CM-PSO and modified GA without trapping in local minima. Validation is conducted by designing a single-element and simple-structure dipole antenna so that its optimized S 11 is better than -30 dB at the resonance frequency and covers the 3.3 to 3.8 GHz fre- quency band with S 11 < − 1 0 dB. Certainly, the -30 dB and covering frequency band criteria can be modified in the pro- posed algorithm. In the algorithm, the isolation between el- ements of a quad-Multiple-Input/Multiple-Output antenna, constructed using optimized dipole antennas, is set to be less than -20 dB (changeable criteria) so that the smallest size can be achieved. CST carries out electromagnetic and high- frequency simulations, and the novel developed optimization algorithm in MATLAB determines what and how much pa- rameter values need to be changed by CM-PSO or an innova- tive modified GA in order to enhance the antenna’s S 11 result and its Impedance Bandwidth (IBW). The input parameters of the algorithm are the dimensions of the proposed antenna’s elements, which significantly influence its performance.

“…Many techniques have been used in the literature for improving isolation. The techniques can be categorised into four broad approaches, namely, polarisation diversity (Taki and Abou-Rjeily, 2022; Adamiuk et al , 2009; Aboufoul et al , 2012; Osman et al , 2016; Peristerianos et al , 2016; Kaur et al , 2021; Sghaier and Latrach, 2021; Kim-Thi and Tran, 2021), quasi-self-complementary approach (Zhu et al , 2016; Khattak et al , 2021), pattern diversity (Tao and Feng, 2016; Divya et al , 2021; Dahl et al , 2017; Reddy et al , 2015; Sohi and Kaur, 2020) and usage of additional decoupling structures (Chacko et al , 2013; Xie et al , 2013; Chattha et al , 2013; Mao and Chu, 2014; MoradiKordalivand et al , 2014; Kang et al , 2015; Ramachandran et al , 2016; Chao-Ming et al , 2015; Bannered et al , 2017; Rajkumar et al , 2015; Deng et al , 2016; Li et al , 2013; Masoodi et al , 2020; Thakur et al , 2021; Abed et al , 2021; Singh et al , 2021; Kaboutari and Hosseini, 2021).

“…Compact dual and four elements MIMO antenna with decoupling circuit provides better performance in isolation and the impedance matching (Singh et al , 2021). Four element dragonfly shaped radiators and four stepped ground plane are placed orthogonally with decoupling element gives improvement in isolation and frequency interference is low (Kaboutari and Hosseini, 2021). In Sohi and Kaur (2020), 2 × 2 complementary Sierpinski fractal array antenna was designed to improve the performance of the bandwidth and pattern diversity.…”

Purpose This paper aims to propose a single element, dual feed, polarisation diversity antenna. The proposed antenna operates from 2.9 to 10.6 GHz for covering the entire ultra-wideband (UWB) frequency range. The antenna is designed for usage in massive multiple input multiple output (MIMO) and closed packaging applications. Design/methodology/approach The size of the antenna is 24 × 24 × 1.6 mm3. The radiating element of the antenna is derived from the Sierpinski–Knopp (SK) fractal geometry for miniaturization of the antenna size. The antenna has a single reflecting stub placed between the two orthogonal feeds, to improve isolation. Findings The proposed antenna system exhibits S11 < −10 dB, S21 < −15 dB and stable radiation characteristics in the entire operating region. It also offers an envelope correlation coefficient < 0.01, a diversity gain > 9.9 dB and a capacity loss < 0.4 bps/Hz. The simulated and measured outputs were compared and results were found to be in similarity. Originality/value The proposed UWB-MIMO antenna has significant size reduction through usage of SK fractal geometry for radiating element. The antenna uses a single radiating element with dual feed. The stub is between the antenna elements which provide a compact and miniaturized MIMO solution for high density packaging applications. The UWB-MIMO antenna provides an isolation better than −20 dB in the entire UWB operating band.
