Abstract-During the past ten years, a great interest in the research of metamaterials has been observed. Metamaterials are artificially invented materials that show the properties which are not detected in naturally occurring materials. Metamaterials exhibits negative permittivity and/ or negative permeability. This paper presents a review of different types of metamaterials, their own unique properties and advantages. Keywords-Metamaterials(MTM),

“…Although these antennas are miniaturized in nature, it faces a problem of narrow bandwidth [11,12], poor gain and radiation efficiency [13,14]. In the last few years, several works have been outlined, which claim the improvement in bandwidth and radiation efficiency [15][16][17][18][19]. In [16], a close ring resonator (CRR) is applied to design a dual-band MTM antenna.…”

“…Ref. [17] presents a new aspect for bandwidth enhancement with the use of array of mushroom MTM structure. Further, bandwidth enhancement is achieved by forming an array of left-handed material unit cell and utilizing the left-handed material's concept of phase compensation and coupled resonance [18].…”

Abstract-A compact coplanar waveguide (CPW) fed close ring resonator (CRR) loaded four-element metamaterial (MTM) array antenna for wireless application is designed and discussed in this article. The array is designed with corporate feeding network, arranged in a manner to offer 3 dB power at its each element. The proposed 1 × 4 MTM array antenna offers a fractional bandwidth of 10.18% with respect to the resonance frequency of f r = 2.26 GHz. At the resonance frequency of 2.26 GHz, the proposed 1 × 4 MTM array antenna offers a gain of 5.10 dBi in the direction of broadside radiation. Each element of the proposed array antenna consists of CRR, which removes the requirement of via and allows the design of a uniplanar MTM array. The overall electrical size of the single element antenna shows compactness of 0.255λ 0 ×0.155λ 0 ×0.012λ 0 , where λ 0 is the free space wavelength at its resonance frequency of f r = 2.3 GHz. The proposed MTM array antenna is designed and simulated on ANSYS HFSS 14.0, and simulated results are verified with the fabricated proto-type.

“…The modied split-ring resonator structure with capacitively loaded strips result in a wide bandwidth [4]. In reference [5], by using the dual resonant modes, the fractional bandwidth is increased up to 25%. With the aid of reactive loading, a multiband metamaterial monopole antenna is proposed in [6].…”

Abstract-A metamaterial-based broadband antenna loaded with artificial impedance surface (AIS) is presented in this letter. Two metallic vias connect a Y-shaped patch to the ground plane. The patch, two metallic vias, and the AIS compose an epsilon negative (ENG) transmission line (TL). The asymmetry Y-shaped patch and the AIS bring about the first-order resonance (FOR) and second-order resonance (SOR) modes, which can be merged into one passband to yield a wideband property. The proposed ENG-TL resonant antenna has the advantages of compact size, wide bandwidth, and high gain, which can be applied to portable and handheld communication system.
