HIGH GAIN METASURFACE ANTENNA FOR 5G WIRELESS COMMUNICATION

Abstract

This paper presents the design, simulation, and performance enhancement of a metasurface-based wideband planar antenna tailored for millimetre-wave (mmWave) applications. Based on a metasurface reflector-backed configuration, systematic improvements in antenna performance are achieved by scaling the metasurface array and optimizing the radiating structure. The Simulation results reveal a significant gain enhancement with each design stage: the 3×2 array achieved a gain of 9.46 dBi, the 3×3 modified array yielded 11.22 dBi, and the 4×4 final configuration reached a peak gain of 11.81 dBi. Further, the proposed antenna system offers 17 GHz of impedance bandwidth as compared to the original design, which achieved approximately 15.8 GHz. Also, it highlights the effectiveness of metasurface array optimization as a pathway for gain-focused antenna design without severely compromising impedance bandwidth performance.
