“…The design achieved an ECC below 0.10 and isolation greater than 15 dB. The manuscript [ 72 ] presented a reconfigurable square patch radiator that used plasma polarization for 4G/5G wireless communication. The MSA incorporated two pairs of square boxes of different sizes with orientation angles of 45° and 135° etched with plasma states that varied the polarization.…”

Multiple-input multiple-output (MIMO) technology has emerged as a highly promising solution for wireless communication, offering an opportunity to overcome the limitations of traffic capacity in high-speed broadband wireless network access. By utilizing multiple antennas at both the transmitting and receiving ends, the MIMO system enhances the efficiency and performance of wireless communication systems. This manuscript specifies a comprehensive review of MIMO antenna design approaches for fifth generation (5G) and beyond. With an introductory glimpse of cellular generation and the frequency spectrum for 5G, profound key enabling technologies for 5G mobile communication are presented. A detailed analysis of MIMO performance parameters in terms of envelope correlation coefficient (ECC), total active reflection coefficient (TARC), mean effective gain (MEG), and isolation is presented along with the advantages of MIMO technology over conventional SISO systems. MIMO is characterized and the performance is compared based on wideband/ultra-wideband, multiband/reconfigurable, circular polarized wideband/circular polarized ultra-wideband/circular polarized multiband, and reconfigurable categories. The design approaches of MIMO antennas for various 5G bands are discussed. It is subsequently enriched with the detailed studies of wideband (WB)/ultra-wideband (UWB), multiband, and circular polarized MIMO antennas with different design techniques. A good MIMO antenna system should be well decoupled among different ports to enhance its performance, and hence isolation among different ports is a crucial factor in designing high-performance MIMO antennas. A summary of design approaches with improved isolation is presented. The manuscript summarizes the various MIMO antenna design aspects for NR FR-1 (new radio frequency range) and NR FR-2, which will benefit researchers in the field of 5G and forthcoming cellular generations.

“…The antennas are important devices because they perform the receiver and transmission of signals, which should present a compact structure, low-cost, circular polarization, and wideband. Several techniques are used in antennas to modify the shape and parameters, including fractal and bioinspired technologies [1][2][3][4][5].…”

“…Bioinspired antennas are devices that use shapes of living beings to alter some antenna response parameters and are used in several applications, such as narrow-band, wideband, ultra-wideband, wireless local area network, wireless fidelity, industrial, scientific and medical-ISM, mobile communications, and manifold antenna types, including, patch, planar monopole, aperture, etc. [1][2][3][4][5]. The shapes of the radiating elements of the bioinspired antennas can be generated by several methods, such as drawing in simulator software, and images generated by equations [2,4,5,[11][12][13].…”

In this work, it is proposed the development a monopole directional antenna, bioinspired in elliptical leaf, with aperture by golden ratio, for 4G band application. The shape antenna is generated by Gielis formula, built in FR4 substrate, with apertures calculated by golden ratio, for increasing the antenna perimeter, and to turner the resonance frequency. To compare the results of the bioinspired monopole on the elliptical sheet, a square-shaped monopole antenna was designed, simulated and measured, the structures were designed in the MATLAB program and the simulations were performed in the Ansys program. In the results compared between the square monopole and the bioinspired antenna in the elliptical sheet, it can be seen that the measured bioinspired antenna, compared to the square monopole, presented a bandwidth reduction of 77.27%, a more compact structure, with a reduction of 98%, covering the wireless local area network, and long-time evolution 4G at 2.5 GHz. The proposed technique uses a reflector on the ground plane, to change the parameters of the monopole planar antenna, of omnidirectional radiation pattern to a directional, maintaining the characteristics of the broadband, half-power beamwidth great than 100º, with high current density, and similar gain of a directional antenna. From the results, it has been observed that the elliptical leaf monopole antenna shows broadband characteristics, with a half-power beamwidth of 128 degrees, wideband, the bandwidth of 500 MHz, a gain of 6.28 dBi, a current density of 13.01 A/m², and circular polarization.
