Reconfigurable intelligent surfaces with smart antenna opportunities and challenges.

The prime objective of this research is to plunge into how Reconfigurable Intelligent Surface (RIS) can integrate with sophisticated antenna array systems. The main aim is to design a new wireless antenna setup. The study concentrates on merging these cutting-edge technologies to pioneer advancements in wireless antennas. The main aim is to surpass the limitations that come with traditional wireless communication systems. According to this paper, a system performs best when it blends RIS and an intelligent antenna. In addition, this paper shows that the opportunities and challenges of RIS in recent works. Moreover, this combined use of smart antennas not only uses them for beamforming but also uses their maser feature as well thus enhancing more control over. [ABSTRACT FROM AUTHOR]
