The present technology fulfills the requirement of high data rate and high channel capacity using multiple input multiple output (MIMO) technology. The MIMO capacity of the system is increased linearly but due to the multiple antennas placed near to each other, problem of mutual coupling exists, which degrades the maximum achievable performance of the system. The problems of multipath propagation can be solved using MIMO system. The isolation improvement methods decrease the mutual coupling among antenna elements, and improve the gain and efficiency of the system. In this paper, decoupling network isolation approach, parasitic element approach, defected ground structure, Neutralization line, isolation improvement based on metamaterials, isolation improvement using PIN diode, varactor diode, and feeding structure have been incorporated, and their merits and demerits have been discussed. The effect of different permittivity material on antenna parameters has also included.

“…An electromagnetic bandgap (EBG) is just a structure that may either block or transmit electromagnetic waves of a particular frequency. 92 Depending on the application, different stopband, passband, and bandgap frequencies can be determined. 93 This structure is disguised by a periodic array of metallic or dielectric material.…”

The rapid increase in the innovation of fifth-generation (5th G) technology is a critical indicator of an explosion in technologies that satisfy everyday needs, and antennas for 5G with reduced delay, minimal path loss, and a continuous pattern of radiation will be essential. The upcoming 5G Massive multiple inputs, multiple outputs (MIMO) antenna will improve the performance of future-generation wireless communication systems. The primary advantages of 5G technologies are their greater transmission speeds, extremely high data rates, improved reliability, less latency, enhanced spectral efficiencies, and the possibility of connecting a greater number of wireless devices to the networks. The Massive MIMO antenna is one of the most anticipated 5G technologies, which boosts the capacity compared to a conventional MIMO antenna, increasing the spectral efficiency by 50 times. In this review article, we discussed mutual coupling and then techniques and how to reduce the coupling between antennas. The goal of this study is to look at the huge MIMO antennas from a number of different angles.

“…Several techniques in literature have been reported so far, to decrease the mutual coupling and to enhance the isolation of MIMO antenna. The defected ground structure (DGS) approach can be utilized for varying the orientation of the surface current and sometimes to perturb the surface current distribution on the path and thus produce high isolation 4–7 . The metamaterial (MTM) is also an approach to minimize the mutual coupling 8,9 .…”

This work proposes an electrical compact triple-bands antenna founded on a composite left-/right-handed approach. This structure contains a rectangular patch combined with two unit cells based on the metamaterial properties that are used to produce wide electrical lengths in miniature physical sizes. Thus, the presented antenna is designed with a lower resonant frequency and miniature physical dimensions compared to conventional antennas. The suggested antenna has been produced on top of the FR4 substrate having tan δ = 0.022, εr = 4.58, and a size of 28 Â 16 Â 1.6 mm 3 . This structure provides three bandwidths of (2.391-2.54 GHz), (3.42-3.56 GHz), and (5.02-11.40 GHz). Additionally, a multi-input multioutput (MIMO) antenna is designed by placing two similar radiating patches in a perpendicular shape. Therefore, this design approach has been used to achieve an important isolation among ports and less than À30 dB at frequency bands. The results of radiation patterns, envelope correlation coefficient, diversity gain, and channel capacity loss are below to 0.06, 10 dB, and 0.4 b/s/Hz respectively, which confirms that the MIMO antenna is compatible with wireless MIMO devices. These antennas have been modeled and experimentally confirmed, and the results have proven that the suggested antennas are useable and can support multi-standard wireless applications.
