“…Metamaterials are new materials that are made up of the arrangement of metal structures on the surface of dielectric substrates. Therefore, the physical properties of metamaterials depend on their structures more than the component that makes up them.The effects created by the metamaterials can be observed during the transmission of electromagnetic waves such as wave propagation.This phenomenon occurs due to an antiparallel group and the phase velocity leads to the inversion of the wave fronts, while its energy is moving away from the source.Metamaterial can be used for microwave fields in devices such as antennas, filters, integrated network sensors, or new superlayers that can improve some of the parameters of equipment in the different field of science and technology.In this medium, the poynting vector has the opposite direction to the propagation vector, so that it can support backward waves, i.e., the energy and wave fronts travel in opposite directions [39][40][41].…”

“…The metamaterial antenna is one or more layers of metamaterials that are used as substrates or in addition to the configuration of the antenna to improve its performances. From scientific research shows that the application of metamaterials in the antenna design can enhance the radiated power, improve antenna parameters and reduce the size of the antenna [39][40][41].…”

This paper presents the introduction of a miniaturised and enhanced horn antenna that is loaded with a linear or triangular planar array of Circular Spiral-Line Structures (CSLS). A CSLS array was placed inside the horn aperture in order to reduce the size of the suggested horn antenna.The antenna's resonance frequency when loaded with CSLS array is 6.3 GHz, and when it is not loaded, it is 8 GHz.The dimensions of the antenna aperture and axial length would be 150×138×103 mm 3 if it were intended for 6.3 GHz.However, by loading the CSLS array, the 8 GHz antenna's dimensions are reduced to 90×57×130 mm 3 , and a shift in resonance frequency from 8 GHz to 6.3 GHz results in a 68.7% miniaturisation in size.With the CSLS array put into the suggested antenna, the antenna's Bandwidth Improvement percentage (BWI) increases to 8.7%, the Enhanced Return Loss Ratio (ERLR) increases to 26.2 , maximum power intenisity Umax= 1.8 W/Str., directivity D= 25.8 dB, gain G=24.6 dB, radiated power Pr=0.92 for one watt input power Pin and radition efficiency e0 reaches to 95% for the proposed horn loaded with CSLS arrays compared with the horn without arrays .The SLSM linear array was designed and manufactured with a Rogers of εr=10.2 and thickness of 0.635 mm.An introduction and analysis are given to the laboratory test and measurement for the CSLS linear array loaded in the WR90 rectangular waveguide.Finite Element Method (FEM) based, HFSS, is used for the design and analysis of the proposed structures.

In the recent era, fifth-generation technology (5G) has not been fully implemented in the realm of wireless communication. To Have excellent accessible bandwidth feasibility, and in order to achieve the aims of 5G standards, such as higher data rates and ultrahigh-definition video streaming, the millimeter wave (mmWave) band must be employed. Services with minimal latency and many other features are feasible only in the mmWave spectrum. To avoid numerous communication complexities such as high connection losses, short wavelength, and restricted bandwidth, as well as path-loss challenges in the mmWave range, an antenna with wide bandwidth, high gain, narrow steerable beam, high isolation, low side-lobe levels, and multiband features is required to alleviate these difficulties and meet 5G communication standards. To overcome these challenges, specific strategies and techniques should be employed in the traditional antenna designing procedure to excellently improve the performance of the antenna in terms of bandwidth, gain, and efficiency and to reduce the mutual coupling effect between the closely colocated antenna elements in MIMOs and arrays. The researchers reported on a variety of bandwidth and gain improvement approaches. To gain broader coverage, traditional antenna design techniques must be modified. In this study, the latest state-of-the-art work is reviewed, such as the role of the metamaterials (MMTs), parasitic patches, hybrid feeding, EBG structure, impact of the slots with different geometrical shapes in the radiator to achieve the goal of wide bandwidth, boosted gain, reduced side-lobes level, as well as stable radiation properties. Mutual coupling reduction techniques are also briefly reported. The role of reconfigurability is focused on in this study, and at the end, the future challenges in the field of antenna design and possible remedies to such issues are reviewed.

“…The presence of the plasma excites an electron plasma (EP) waves in addition to the usual electromagnetic (EM) waves. Radiation properties of a circular patch microstrip antenna are already studied in plasma medium using cavity model and results are presented elsewhere [4].Due to the conical depression of circular patch surface into the substrate by an angle  , an additional electric field in the radial direction will be introduced which will give rise to extra radiations. Using this additional field in addition to the already existing fields, radiation properties of a conically depressed micro-strip patch antenna are studied in warm ionized plasma medium.…”

In connection with the development of radio communication systems, microwave, millimeter range, one of the most important is the problem of creating compact solid-state radiation sources. The antenna is the effective interaction between electronic circuits and the outside world is an important component of any wireless connection trend toward line the use of high frequencies in modern communications. Solutions, space technology, about (30 Ghz), Local Multipoint Distribution (LMDS) at 28Ghz) antenna technologies to meet the new requirements of the card actively participated in the elaboration of the various subsystems for such active monolithic Phased Array Antenna. This document is primarily.This paper mainly studies the effect of plasma wave on the radiation properties of a conically depressed microstrip patch antenna. Using linearized hydrodynamic theory and potential function technique, the total directive gain and quality factor are calculated for different values of plasma to source frequency and different half-cone angles. It is observed that the directive gain and quality factor are changes considerably by changing the half-cone angle as well as a plasma to source frequency values. © 2018 JASET, International Scholars and Researchers Association.
