Design and Implementation of Hexagonal Shaped 2x2 Array Antenna for 5G Applications

Array antennas have become increasingly significant in modern communication and sensing systems. This project explores the key aspects of wearable antennas, emphasizing their design considerations, challenges and applications. The miniaturization and integration of antennas into clothing or accessories pose unique engineering challenges such as limited space, flexibility, and user comfort. Various techniques, including flexible materials, conformal designs and innovative geometries, address these challenges.This project presents a geo-textile material that is a polypropylene-based meta material-loaded wearable Hexagonal - shaped 2x2 micro strip patch antenna array, having Substrate Size=230*260*0.2mm3, Ground plane size = 230*260 mm2, Patch Radius=34mm, operating at 2.45GHz, a frequency band widely adopted in 5G and having high gain i.e.,31.14dB at 2.42GHz for public safety band applications. Under the unloaded condition of the micro strip patch antenna, poor matching is observed in the public safety band. Further, this antenna is loaded with hexagonal shaped 2x2 antenna array. This array loading provides better-matched conditions in the public safety band.
