Antenna miniaturization is a typical trend in contemporary wireless systems, notably for current wireless technology, to meet multiband needs while preserving high transmission qualities. The terahertz (THz) regime is helpful in advanced applications and significantly impacts wireless technology. This paper proposes a double-layered hexagonal split ring resonator (HSRR) based on a microstrip patch antenna (MPA) and analyzes the simulated characteristics. The HSRR width is varied for different thickness "w" values and compares the analysis of with and without HSRR in the antenna. Due to the impact of metamaterials, the optimized antenna produces À44.02-dB return loss, 1.012 voltage standing wave ratio (VSWR), 6.47-dBi gain, and 4.78-dB directivity at 1.8-THz frequency. This proposed antenna is suitable for THz applications, which include high-speed data rate in wireless communication, bio-medical field, and THz spectrometer.
