“…A rigorous study of metamaterial application in microstrip patch antenna designing has been reported in [27]. It has been observed that the metamaterial is quite often used in antenna miniaturization [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46], performance improvement of on-chip antennas in THz frequency band [47,48], designing of impedance matching network [49,50], microwave imaging [51], and mutual coupling reduction in MIMO and SAR antennas [52][53][54][55][56][57][58][59][60][61][62]. Some of the examples of antenna performances under the influence of metamaterial have been listed in the table below (Table 1).…”

Metamaterials are artificially configured composite materials exhibiting unique characteristics such as negative effective permittivity and permeability. Due to these distinctive characteristics, metamaterials have drawn special attention in designing novel antenna structures and improving antenna performances. The application of metamaterial in antenna technology significantly brings miniaturization to the antenna structure, enhances the impedance bandwidth, gain, and efficiency of the antenna as well as improves isolation between the MIMO antenna elements. The substrate integrated waveguide (SIW) reduces the conductor and dielectric loss, and surface wave excitations in the antennas. Although an overview of the performance enhancement of microstrip patch antennas under the influence of metamaterial has been incorporated in this article, the authors have put more effort in presenting a detailed study on working mechanism of metamaterial-based SIW antennas. Thus, a detailed review of the novel designs of metamaterial-inspired SIW cavity-backed slot antennas (CBSA), leaky-wave antennas (LWA), aperture antennas, and H-plane horn antennas has been included. The theoretical background of the metamaterials characteristics has been presented. Moreover, the working principles of metamaterial-based SIW CBSAs, SIW LWAs, SIW aperture antennas, and SIW H-plane horn antennas have been thoroughly outlined in obtaining antenna miniaturization, gain enhancement, beam steering through frequency scanning, polarization flexibility, bandwidth broadening, and isolation improvement. Besides this, a study has also been included in eliminating the limitations of SIW on-chip antennas such as narrow bandwidth, low gain, and efficiency by including metamaterial/metasurface in the antenna designs. Although the emphasis has been given to elaborating the attractive antenna performances, some design limitations have also been identified, and those need further investigation. This survey brings up not only the conceptual framework of the attractive characteristics of metamaterial, the design methodology of the non-resonant type metamaterial in the SIW environment, and the working principles of metamaterial-inspired SIW antennas but also the design limitations. Thus, consideration can be given to this article as the potential design guidelines of the metamaterial-based SIW antennas, and possible ideas can be obtained for doing further advanced research on the identified research gaps.

Based on microstrip antenna technology, a compact single-layer circular aperture array is proposed in this paper. The proposed method is suitable for designing large-scale and high-efficiency patch array in Ka band. By using the high-impedance characteristic of the coupled microstrip line, a novel multi-stage feeding network that can realize large power division ratio is proposed, and its structure is center-symmetrical and is fed through a coaxial probe at the center. The parallel branch of the multi-stage divider is connected to the row array, and the array elements can obtain uniform excitation through the design of the division ratio of each stage. A 256-element patch array operating at 35 GHz is proposed, the length and width of the antenna unit are 2.74 mm and 3 mm, respectively, the horizontal spacing between the array elements is 0.742λ0, the vertical spacing varies from 0.677λ0 to 0.737λ0, and the radius of the proposed array is 60 mm (7λ0 at 35 GHz). At the end, a prototype is fabricated and measured, the measured results show that the maximum gain is 29.5 dBi at 35 GHz, which correspond to the radiation efficiency and aperture efficiency of 61.66% and 46.07%, respectively, and the results show that the proposed antenna achieves high efficiency in Ka band, which verifies the correctness of the design. The proposed array antenna is compact in structure and only needs single-layer design, which can achieve high efficiency and low in manufacture cost, which is an excellent candidate for millimeter-wave large-scale array application.

“…The designed lens is composed of isotropic but inhomogeneous metamaterials that can provide impedance matching with free space. A few other examples of impedance-matched devices based on electromagnetic metamaterials can be found in [19][20][21]. In conclusion, the interest in impedance-matched GRIN metamaterials is growing in many applications, with an increasing need for general analytical and numerical studies of impedance-matched metamaterial composites.…”

This paper presents analytical and numerical studies of electromagnetic wave propagation through an interface between a regular right-handed material (RHM) and a left-handed metamaterial (LHM). The interface is graded along the direction perpendicular to the boundary plane between the two materials, chosen to be the x-direction. The permittivity ε(ω, x) and permeability µ(ω, x) are chosen to vary according to hyperbolic tangent functions. We show that the field intensities for both TE-and TMcases satisfy the same differential equations, and we obtain remarkably simple exact analytical solutions to Helmholtz' equations for lossy media. The obtained exact analytical results for the field intensities along the graded RHM-LHM composite confirm all the expected properties of RHM-LHM structures. Finally, we perform a numerical study of the wave propagation over an impedance-matched graded RHM-LHM interface, using the software COMSOL Multiphysics, and obtain an excellent agreement between the numerical simulations and analytical results. The results obtained in the present paper are not limited to any particular application, and are generally useful for all cases of wave propagation over impedance-matched two-and three-dimensional interfaces between RHM and LHM media. The advantage of the present method is that it can model smooth realistic material transitions, while at the same time including the abrupt transition as a limiting case. Furthermore, unlike previously existing solutions, the interface width is included as a parameter in the analytical solutions in a very simple way. This enables the use of the interface width as an additional degree of freedom in the design of practical RHM-LHM interfaces.
