“…In this respect, the emerging notion of metamaterial with different resonator unit shapes has played a great role in reducing the complexity incurred due to the addition of extra structures and improving performance of antennas . In this section, the bandwidth enhancement techniques will be presented by categorizing them based on the placement of metamaterial structure on/near the patch, loaded/etched in the ground plane, embedded in the substrate, and as superstrate …”

Metamaterials are assemblies of metallic and/or dielectric materials with properties that are not readily found in naturally existing materials. Hence, metamaterial structures are commonly loaded on/near the patch, embedded in the substrate, loaded/etched from the ground plane or placed as a superstrate layer for enhancing bandwidth and gain, and size miniaturization of conventional patch antennas. The demand for wide bandwidth, high gain, and compact antennas is highly contemplated in recent wireless communication research studies. Despite their lightweight, ease of fabrication, low profile, and simplicity for integration, patch antennas have performance limitations as result of their narrow bandwidth, lower gain, larger size, and lower power handling capacity. To address these problems, metamaterial‐based antennas have gained massive interest. There exist inadequate literatures about review of current state of extensive study reports on metamaterial application for patch antenna performance enhancement. Thus, this paper has reviewed and discussed latest research works on metamaterial applications for performance enhancement of planar patch antennas.

“…Because of unconventional properties such as negative permittivity and permeability, metamaterial (MTM) antennas are a well suited alternative to meet the demand for miniaturized antennas [1][2][3]. These MTM antennas are based on the concept of composite right-and left-handed, epsilon negative and mu negative transmission lines [4][5][6][7][8][9][10].…”

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.

“…This theoretical idea has been used for the development of magneto‐dielectric substrate in a goal of squeezing antenna dimension and bandwidth enhancement. With the introduction of metamaterial concepts and the advent of MTMs structures a new dimension in the miniaturization domain has been opened out . A circular patch antenna is miniaturized in sub wavelength region by MNG material which is realized using split ring resonator (SRR) and helical configuration, respectively.…”

In this article, to construct a reactive impedance substrate, unit ring is designed and proposed with radial and concentric mode analysis. A cylindrical substrate backed with a PEC plane and circular metallic elements on the top is used for achieving reactive surface impedance behavior. In this aspect, three unit rings structure with different ring elements are designed and simulated to realize the reflection phase characteristics. Afterwards, a probe‐fed circular patch antenna is miniaturized by stacking the three‐ring circular reactive impedance surface. The fundamental resonance frequency of the proposed antenna is reduced by about 30% with an improvement in impedance bandwidth by 121.6%. An improved front‐to‐back ratio as well as an acceptable co‐pol and cross‐pol isolation is exhibited in both E‐plane and H‐plane at the resonance frequency. In addition of miniaturization, dual band behavior has also been observed in the proposed design. Both resonance phenomena have been explained by circuit model representation and surface current distribution analysis. Improved radiation efficiency at 81.5% has been measured for the proposed antenna configuration.
