Abstract
In fifth-generation (5G) and later networks, the growing demand for high data rates in modern wireless communication systems has established millimeter-wave (mm-wave) frequencies as a fundamental resource. Nevertheless, especially with regard to gain, bandwidth, and efficiency, conventional antenna designs usually find it difficult to meet the strict performance criteria at these high frequencies. Artificial designed objects with electromagnetic properties not usually found in nature have become a good way to solve these limitations: metamaterials. This paper presents a thorough investigation of how metamaterials affect the performance enhancement of antennas operating in millimeter-wave systems. The analysis covers several approaches applied in the design and evaluation of mm-wave antennas enhanced by metamaterials, including advanced computational modeling and experimental characterizing methods. With some cases spanning 60% of the operational frequency range, literature reveals amazing increases in antenna gain—often above 13 dBi—and significant bandwidth gains. Furthermore, metamaterials have shown great radiation efficiency; in some cases, they reach 94% in particular configurations. Surface wave suppression, negative refractive index, and the development of resonant cavities—among other unique electromagnetic manipulating characteristics of metamaterials—are credited with the performance improvements. These developments have important consequences for the future of mm-wave communication systems since they enable more reliable and effective high-speed data transfer over several applications, including radar systems, wearable technologies, and cellular networks, which emphasizes possible future directions for research and development in this fast advancing field.
