This paper proposes a metamaterial‐based multilayer antenna for WiFi and WiMAX applications. The multilayer structure is beneficial for achieving a gain of more than 15 dB. The substrate is made of FR‐4, and the superstrate is Rogers RT/duroid 5880 with a dielectric constant of 2.2 and a loss tangent of 0.009. The desired metamaterial structure is realized using metallic square rings printed on the superstrate. The thickness of the substrate is 1.58 mm, and the overall area of the antenna is 105×72.5 mm2. Using an area‐efficient multilayer configuration for this microstrip antenna, its gain is cost‐effectively enhanced to more than 18 dB, and the shape of the radiation patterns is also appropriate. This antenna is fabricated and fully measured; the measurement and simulation results are in excellent agreement.

“…Recently, metasurfaces (MSs) have attracted growing interests of many researchers due to their planar profile, easy fabrication, and also strong beam control capacity [1][2][3][4][5][6]. For phase gradient metasurfaces (PGMS), proposed by Yu et al [7], a wide range of applications have been found, such as anomalous beam bending [8,9], focusing [7,10], surface-plasmon-polariton coupling [11,12], and polarization manipulation. With the ability of tuning the phase range covering 2π, metasurface can be used to improve performance of antenna.…”

Recently, metasurfaces (MSs) have received tremendous attention because their electromagnetic properties can be controlled at will. Generally, metasurface with hyperbolic phase distributions, namely, focusing metasurface, can be used to design high-gain antennas. Besides, metasurface has the ability of controlling the polarization state of electromagnetic wave. In this chapter, we first propose a new ultrathin broadband reflected MS and take it into application for high-gain planar antenna. Then, we propose multilayer multifunctional transmitted MSs to simultaneously enhance the gain and transform the linear polarization to circular polarization of the patch antenna. This kind of high-gain antenna eliminates the feed-block effect of the reflected ones.

“…Due to the exotic features, an appropriate combination of metasurfaces has been found to enhance the MIMO antenna performances such as isolation, gain, and bandwidth. For example, by placing a metasurface above or below of patch resonator, the antenna performance has been reported to enhance markedly [2,11,12,13,14,15,23]. The mechanism for enhancement of the antenna performance is due to the formation of surface wave resonance that creates surface wave propagation along the metasurface for extra resonance [2].…”

Developing a millimeter-wave (mm-wave) antenna that enables wide bandwidth with its operating band covering the entire global 5G spectrum is highly desirable but very challenging for achieving both compact size and high-performance antenna. Herein, the mm-wave microstrip patch antenna (MPA) and its multiple-input multiple-output (MIMO) configuration based on the metasurfaces for 5G system applications are proposed and investigated by the simulation method. To improve performance and keep the low-profile and low-cost MPA antenna, square ring resonator (SQRR) metasurface and radiating patch are printed on a single dielectric layer. With the presence of the metasurfaces that acting as a secondary radiator, the performance of the designed antenna is significantly improved with a wide operating band in the range of 23.9-30.7 GHz, high peak gain of 9.4 dBic, and radiation efficiency of above 87%. Based on this design, four-port MIMO antenna configuration is performed for evaluating a MIMO system that realizes the advantage features such as compact size, wide bandwidth covering the entire global mm-wave 5G spectrum band of 24.25-29.5 GHz, and excellent diversity performance characterized by good isolation between the adjacent elements and low envelope correlation coefficient. Thus, the MIMO antenna design is a very promising candidate for 5G MIMO mm-wave applications, specifically in cellular systems.
