“…Surprisingly, this setup produces a very focused beam pattern with a gain of 6.88 dB in the desired direction. [9].A small 4 x 4 multiple-input, multiple-output (MIMO) antenna array is used in the suggested method, and it is supplemented by a neutralization line (NL) that is just 40 mm by 40 mm by 6 mm in size.…”

In this study, the aim is to minimize interference between closely spaced micro strip patch antenna elements, and we achieved this by developing various techniques. The recent trends in wireless applications is one of multiple input multiple output design, which has increased the need for multiple antenna integration in the user's equipment. Without using additional power or frequency band, a MIMO antenna is utilized to increase the channel's capacity. It necessitates a large number of antennas configured in the transmitter with minimal connection. Statistical Therefore, low mutual coupling between the antennas is necessary for an effective MIMO antenna system. The paper examines numerous isolation methods put out in recent years. It includes a thorough investigation of design concerns like antenna downsizing, integration problems, antenna coupling, and isolation improvement methods.

“…Hence, the mutual coupling between two components can be minimized. For MIMO antenna characterisation, the envelope correlation coefficient (ECC) (ρ e ) and diversity gain (G d ) are important parameters to quantify signal interference between channels [12], [13]. In principle, ECC is a measure of crosstalk among MIMO channels, approximately expressed in terms of the S-parameters of the MIMO antenna system [12]:…”

A tri-band 2×2 MIMO antenna array for 5G applications is presented. It consists of two orthogonally-placed compact tri-band 28/38/60 GHz antennas with the realized gain varying between 3.5 and 8.5 dBi over the operating frequencies. Each individual antenna maintains a monopole-like radiation pattern across these bands. In addition, the MIMO characterization of the proposed array is discussed. The simulation results show that the envelope correlation coefficient of the array is excellent with a maximum value of less than 0.0015 whereas the diversity gain almost attains 10 dB over the entire operating frequency. The simple planar structure of the MIMO array also offers an ease of fabrication and practical integration with other electronic components Index Terms-Ultra wideband antenna, multi-band antenna, MIMO antenna, 5G antenna.
