Metamaterials have witnessed plentiful and quick development in the recent century as a primary strategy for manipulating electromagnetic (EM) waves. Metamaterials have developed adaptable and potent approaches for regulating EM waves and several novel applications that would be hard to accomplish with natural substances. Though metallic elements are commonly used to build metamaterials, nonmetallic elements may also be used. This article addressed the performances of a pentagonal split ring resonator (PSRR) based microstrip patch antenna (MPA) and the PSRR antenna is resonated at 1.4 THz. The antenna performances of the PSRR antenna are investigated by two different scenarios using computer simulation technology tool. In the first case, the structure of PSRR structure is varied for different angles such as 0º, 45º, 90º, 135º, 180º, 225º, 270º and 315º. The optimized PSRR structure is further analyzed by varying the split gap of the outer and inner pentagonal ring. With the influence of a dual-layer pentagonal ring, the patch antenna produces an excellent result of -61.97dB return loss, 1.000 VSWR, 6.75 dB of gain and 7.86 dB directivity. Hence, the proposed PSRR antenna is suitable for high-speed wireless applications and various THz devices..
