“…It is noticed that the presented AMC structure is characterized with the four zero-phases in the reflection coefficient. This AMCbacked antenna exhibits the maximum gain enhancement and possesses three largest relative frequency bandwidths in comparison to other tri-band AMC-backed antennas [26], [28]. Meanwhile, the size of the presented AMC-backed antenna is smaller than the works reported in [12]- [15], and [26].…”

In this paper, a multi-band AMC-backed antenna system characterized with high gain and lowprofile is proposed. It is constructed by placing a quad-band coplanar-waveguide (CPW) antenna over an AMC with four zero-phases in the reflection coefficient. The CPW antenna consists of an ornamental-pillarshaped patch with the specially designed parasitic elements, and a defected ground structure (DGS), for the application in the frequency bands of 2.45, 3.5, 4.6 and 5.8 GHz. To improve the CPW antenna's radiation performance, an artificial magnetic conductor (AMC) ground with four zero-phases of the reflection coefficient is designed and employed as the reflector. The AMC unit cell is composed of four metallic nested rings (FMNR), whose innermost ring is connected in series to four lumped capacitors. It is observed that the proposed quad-band AMC ground can not only increase the gains of the multi-band antenna greatly but also combine the two intermediate frequency bands of the antenna into a broadband one. The prototypes of the antenna and the AMC array with 5 × 5 unit cells were fabricated and measured. It is found that in comparison to the antenna without AMC, the AMC-backed antenna obtains a gain enhancement by amounts of 4.93, 5.92, 5.54 and 4.95 dB at the frequencies of 2.45, 3.5, 4.6 and 5.8 GHz. The 10-dB impedance bandwidths of the AMC-backed antenna include three bands of 2.13-2.87, 3.22-4.75, and 5.54-5.86 GHz, with the corresponding relative bandwidths of 14.8%, 38.4%, and 5.3%. The proposed antenna can be potentially applied to the applications in WLAN, WiMAX, and 5G mobile communication systems. INDEX TERMS multi-band antenna, quad-band artificial magnetic conductor (AMC), coplanar-waveguide (CPW), gain enhancement.

“…This problem even becomes more severe for a multiband antenna especially in lower frequency bands . In this regard, however, metamaterial antennas become the alternative candidates for different communication bands to improve antenna performance characteristics by using metamaterial units as a load on/near the patch, loading/etching from the ground plane, integrating inside the substrate, or making them as superstrate …”

“…The AMC serves as a zero‐degree reflector for the incident wave at the antenna working frequency despite having narrow band in‐phase reflection. The application of AMC beneath the substrate of a CPW fed microstrip antenna resulted in 4.95, 3.88, and 4.13 dBi gain improvement at resonance frequencies of 3.6, 5.86, and 8.53 GHz, respectively. The patch antenna's front and back sides and gain enhancement using the AMC structure are shown in Figure 13A‐C, respectively.…”

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.

“…Various periodic structures such as meta‐material, AMC, and frequency selective surfaces (FSS) are used to increase the gain of single element single band planar antennas . Gain enhancement of a triple band linearly polarized (LP) antenna is discussed in Reference . Increase in gain of linear polarized MIMO antenna is presented in References , however, gain enhancement of circularly polarized antenna for MIMO applications has remained a challenge to the researchers.…”

A dual‐band MIMO slot antenna with polarization diversity and improved gain is proposed in this article. The antenna is composed of two C‐type back‐to‐back connected slot resonators and offers resonances at 3.5 and 5.2 GHz. This antenna element is further used to design a MIMO antenna. By introducing one U‐shaped slot between two antenna elements, isolation between the ports of this MIMO antenna is improved further. Finally, an artificial magnetic conductor (AMC) is placed below the MIMO antenna to enhance its gain. Gain enhancement of 1.5 and 2.2 dB is achieved at lower and upper band, respectively. S‐parameters, radiation patterns, gain, envelope correlation coefficient, and channel capacity loss are investigated to conclude about its performances in MIMO applications. Dual band dual polarization (circular and linear), improved isolation, polarization diversity (right‐hand circular polarization and left‐hand circular polarization), gain enhancement all are presented in a simple design represents the novelty of the proposed MIMO antenna.
