Owing to their remarkable capability to modify electromagnetic waves at microwave and optical frequencies, metasurfaces are now the subject of a substantial amount of study and find utility in a wide variety of applications. These artificial sheet materials, which are typically made up of metallic patches or dielectric etchings in planar or multi-layer confi¬gurations with a thickness of subwavelength, have the benefits of being lightweight, easy to fabricate, and able to control wave propagation both on the surface and in the free space that surrounds it. This article provides an overview of recent advancements in the discipline and organizes those advancements according to their applications. The one-of-a-kind capabilities of many types of metasurfaces have come to light, beginning with the invention of frequency selective surfaces, reconfigurable intelligent surfaces, and metamaterials. Patterning the metasurface unit cells allows for surface impedance to be altered and modified, which has wide-ranging applications in surface wave absorbers and surface waveguides. First and foremost, the purpose of this review article is to provide introductions to the fundamental metasurface, its important features, and application ideas. The authors address the most recent progress in metamaterial-inspired antennas and how they can be used to miniaturize antennas, increase gain and bandwidth, achieve circular polarization, and inhibit mutual coupling in multiple-input multiple-output (MIMO) antenna systems. In conclusion, exploring the research implications of the metasurface development trend and the significant engineering practical applications are shown in the conclusions.
