“…Metamaterial has also been used for gain enhancement of a small antenna which was first theoretically reported by Ziolkowski and Kipple [7]. After that, different properties of metamaterial like low refractive index [8], zero refractive index [9], and high refractive index [10] have been used by the researchers to enhance the antenna gain. Apart from metamaterial, gain or directivity of the antenna has also been increased using different superstrates like electromagnetic band gap (EBG), frequency selective surfaces (FSS), etc.…”

In this paper, a simple approach for enhancing the gain of a planar dipole antenna using the concept of grounded metamaterial (MTM) has been proposed. In this regard, a magnetic metamaterial with Mu-very large (MVL) property has been placed over the ground plane of the antenna to increase the gain of the electric dipole source. A fully planar structure has been configured due to the placement of the metamaterial just over the ground plane. A significant amount of gain improvement of about 3.7 dB for the dipole has been attained using the metamaterial. In addition, increase of fractional bandwidth by 2.2% has been obtained due to the loading of the metamaterial. A comparative study with respect to recently reported literature for the gain enhancement of planar dipole has also been discussed. The proposed antenna is a worthy candidate for wireless communication owing to the high gain, low profile, and wide bandwidth characteristics.

“…The unit cells are constructed from metallic patches or aperture elements that exhibit perfect reflection or transmission, respectively, in the neighbourhood of the resonant element [21]. Many antenna designs based on FSS have been proposed in the literature for the gain enhancement, such as holey superstrate-based antenna [22], a gain-enhanced printed slot antenna using an electric metasurface configuration in [23], and lastly a dual-band patch antenna with FSS reflector for radiation parameters enhancement in [24][25][26][27].…”

“…Over the past few years, the unusual property like negative permittivity, negative permeability and negative refractive index of metamaterials (MTMs) finds tremendous applications in RF, microwave, THz, and even at the optical frequency regime. 6 Recently, different novel characteristics of the MTM structures are successfully utilized to enhance the directivity of various radiating sources such as dipole, 7 monopole, 8 dipole array, 9 microstrip patch, 10 and slot antennas 11,12 by using as the superstrate. Moreover, the presence of air gap between the antenna and MTM superstrate makes the antenna configuration thick in profile.…”

In this article, a highly directive slot antenna design using a parallel incident magnetic metamaterial (MTM) structure has been presented. A split ring resonator (SRR) structure having mu near-zero and epsilon very large with low impedance behavior is employed to enhance the directivity of the antenna. In the proposed optimized design, four-MTM slabs with an array of 2 Â 2 SRR unit cell have been placed perpendicularly over the slot antenna to enhance the directivity. The thickness of utilized MTM slab in the vertical direction is under the optimal condition, which is highly desired to obtain better improvement in directivity. In spite of directivity enhancement of about 6 dB, antenna miniaturization of 11.4% is also obtained due to the loading effect of the MTM slab. The proposed directivity enhancement approach of the slot antenna is established by simulation and verified by measurements. It is perceived from both measured and simulated results that over the whole working band, a significant directivity enhancement is sustained along with reduced backward radiation compared to the unloaded slot.
