“…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 …”

“…From Equation , it can be seen that by handling the reflection coefficient, the proper height of superstrate above the ground plane can be determined for a particular resonance frequency. A Fabry‐Perot antenna coated with a superstrate layer consisting of modified Jerusalem cross and closed ring metamaterial units arranged in a chessboard fashion has been presented in Reference to simultaneously improve the radiation and transmission performances. Figure shows the geometries of the primary antenna, the bottom and top surfaces of the chessboard arranged metamaterial 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.

“…Metasurface have been widely used in the antenna system, such as frequency selective surfaces (FSSs) with spatial filtering performance. One of the most important applications of the FSS is co‐design with antennas, which has many advantages of antennas such as electromagnetic interference elimination, bandwidth broadening, gain and directivity enhancement, and radar cross section (RCS) reduction . To achieve low‐RCS performance, FSSs designed in a special shape reflect electromagnetic waves to other directions.…”

An active band‐notched frequency selective absorber (BNFSA) with switchable notch band is proposed in this article. The BNFSA is a two‐layer structure composed of a lossy layer at the top and a ground plane at the bottom, separated by an air spacer. The element of the lossy layer is a lumped‐resistor‐loaded metallic dipole with a parallel LC resonance structure, which is realized by complementary n‐shaped resonator (CnR) inserted in the center, and PIN diode is welded at two arms of CnR. The bias circuit printed on the back of the substrate of the lossy layer connects to anode and cathode of the diode by via hole and isolates by the inductor. Simulation results show that the notch bands are located at 4.50 and 6.81 GHz when the diode sets to ON and OFF, respectively. To validate the performance of switchable BNFSA, the prototypes are fabricated and measured, reasonable agreement between simulated and measured results is obtained.

“…The gain is enhanced up to 12.5 dBi only at the center frequency of an antenna. A chessboard arranged metamaterial superstrate (CAMS) reported in Reference enhances the gain of an antenna by 4.9 dBi. However, narrow bandwidth and lack of compactness is generally observed in the reported literature.…”

In this article, a high‐gain antenna for ultra‐wideband (UWB) communication is presented and experimentally validated. Gain enhancement is achieved by employing a frequency selective surface (FSS) screen as a superstrate. The proposed antenna‐FSS arrangement is less complex and realized on a low‐profile FR‐4 laminate. The antenna comprises a circular radiator that is enclosed in a triangular shaped arrangement of slots along with a narrow feed‐line. Lengths and widths of the different sections along with feed are optimized to achieve an ultra‐wide impedance bandwidth. The employed superstrate is an array of modified square shaped FSS (MS‐FSS). Full wave analysis validates its effectiveness in achieving at least 5 dBi gain enhancement of the UWB antenna while maintaining wideband impedance match. Moreover, the antenna behavior is also analyzed by varying periodicity and the distance between superstrate and the proposed slot antenna. This antenna‐FSS arrangement is a suitable candidate for high‐gain UWB portable devices.
