“…By strategically placing these passive elements around the antenna design, engineers can optimize its performance for specific applications or requirements. Overall, parasitic elements play a critical role in extending an antenna's capabilities and significantly improving its overall performance through their ability to interact with and modify antenna behavior without the need for direct electrical connections [32,33]. An analysis and a comparison of antenna configurations, including isolation, impedance matching, and gain, are performed.…”

This paper presents a novel, compact, and high gain metasurface (MS) patch antenna. The antenna structure consists of a slotted square patch in a fractal shape, integrated with a metasurface layer stacked on Taconic RF-30 dielectric material. The individual cells are arranged periodically, creating a 5 x 5-layer configuration. The proposed antenna is designed with physical dimensions of 290 x 290 mm² and achieves a maximum gain of 13.3 dBi at a frequency of 2.2 GHz. Moreover, it achieves a satisfactory minimum reflection coefficient of -10.9 dB. The design process and analysis were performed using the CST MWS simulation software. Based on the performance results obtained from this study, the suggested antenna can be considered suitable for applications in 5G communication.

“…By using the combination of parasitic branches with the antenna elements, this design can provide an isolation greater than 30 dB, maintaining a compact size along with good radiation characteristics and dual-polarization. Dual or multi-polarized antennas are in fact a growing trend and the recently published structure found in [62] is one example. Mutual coupling is reduced through a simple parasitic structure consisting of a microstrip L-section array and a microstrip U-section array.…”

In the most recent years multiple-input multiple-output (MIMO) antennas have been widely implemented to take advantage of the opportunity in controlling their radiation pattern and/or polarization in overcoming modern telecommunication systems issues. High levels of mutual coupling can lead to great degradation of an antenna's performance and as such, the study of solutions to minimize its impact was encouraged. This paper provides a literature review of the mutual coupling analysis and its possible mitigation techniques in various systems including massive multiple-input multiple-output (MIMO) systems and mmWaves antennas. Besides going through the main decoupling techniques, this letter compares the different achievements with the respective approaches, and it even allows the understanding of the main advantages and downsides of each one of the techniques studied.

“…In [10,11], a technique called neutralization-line was described that neutralized the coupled reverse current. The parasitic structure was used to enhance isolation in [12,13]. The mutual coupling could also be reduced by directly orthogonal arrangement of antenna elements in [14,15].…”

A compact 4-port coplanar waveguide (CPW) fed ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna with enhanced isolation is proposed to operate from 3.66 GHz to 16.61 GHz with 127.78 % impedance bandwidth. The proposed antenna system consists of four orthogonal arrays of monopole antennas improved by four iterations.The UWB characteristic of the antenna is obtained from an improved monopole antenna fed by CPW. The final MIMO antenna is printed on a Rogers 4003C substrate with dimensions of 60 × 60 × 0.3 mm3.The orthogonal arrangement of antennas brings about the polarization diversity and certain isolation of MIMO antennas.Four rows of orthogonal metasurface elements with via holes and the ring of the backplane further improve the isolation between antenna elements in the MIMO system. The measured results of MIMO antenna agree with the simulated results. The MIMO antenna achieves an impedance bandwidth of 12.95 GHz with S11 < -10 dB and good isolation ( S21 = S41 < -30 dB and S31 < -20 dB). In particular, S31 is always less than -25 dB at frequencies greater than 6 GHz. The optimized MIMO antenna has the advantages of UWB, compact size, good radiation, and enhanced isolation, which shows that it has potential application value in UWB wireless communication systems.
