With an eye on enhancing diagnostic methods, treatment strategies, and wireless health monitoring systems, this article provides a comprehensive overview of the design and development of antennas based on metamaterials for medical purposes. New applications of metamaterials, such as biocompatibility, signal performance enhancements, and miniaturisation of antennas, are the subject of this paper. Due to their significance in medical contexts, three critical design features—impedance matching, radiation efficiency, and specific absorption rate—deserve further analysis. Metamaterials with smaller antennas and broader bandwidths that enhance signal penetration into biological tissues are among the new concepts being researched. Medical imaging, wearable electronics, and implanted devices are rapidly expanding fields in contemporary healthcare technology, and this analysis delves into its antenna applications. The proposed module has been validated using HFSS environment.Adaptive antenna design, multi-functional systems, and improved integration with biological surroundings are just a few of the research topics we suggest as potential solutions to the ever-changing demands of medical technology.
Key words: Specific absorption rate (SAR); antenna miniaturisation; increased bandwidth
