The rapid advancements in wireless communication technologies demand antennas that can efficiently handle the increased data rates, broader frequency spectrum, and enhanced directivity requirements of next-generation networks. Beam-split metasurface antennas (BSMAs) have surfaced as a viable answer to tackle these difficulties, offering a compact and versatile approach for generating multiple beams with high gain and directivity. Among the various metasurface resonator types, split-ring resonators (SRRs) have demonstrated exceptional potential for BSMAs in 5G applications due to their unique structural properties and electromagnetic characteristics. This paper presents a comprehensive overview of the design, fabrication, and performance of SRR-based BSMAs for 5G applications. The fundamental principles of metasurfaces and the role of SRRs in manipulating electromagnetic waves are discussed. The design considerations for SRR-based BSMAs, including resonator geometry, unit cell arrangement, and metasurface substrate selection, are thoroughly examined. Fabrication techniques for SRR-based BSMAs, such as photolithography, etching, and direct laser writing, are described along with their advantages and limitations. The performance of SRR-based BSMAs is evaluated in terms of beam patterns, gain, directivity, and bandwidth. The impact of various design parameters on antenna performance is analyzed. The potential benefits of SRR-based BSMAs in 5G applications, including reduced mutual coupling, enhanced beam steering range, and reduced fabrication cost, are highlighted.
