Design and Analysis of Triangular Split-Ring Resonator–Based Patch Antenna for High-Speed Terahertz Devices

Terahertz (THz) technology is helpful in innovative applications and enormously affects wireless technology. To address THz transmission loss, recent modernizations in digital devices for the ultimate data rate of THz communication systems offer a highly efficient metamaterials (MTM) antenna concept with high directionality. This paper suggests that the dual triangular split-ring resonator (TSRR) structure incorporates the patch antenna function, which works at 1.2 THz. The analysis is carried over by optimizing the triangular ring angle of the TSRR structure’s inner and outer ring width. The optimized TSRR patch antenna with breast phantom produces the excellent result of − 61.54 dB RL, 7.929 dBi gain, 1. 0016 VSWR, and 8.715 dB directivity owing to the influence of MTM structure. The suggested TSRR antenna structure is suitable for various THz applications, which include breast cancer detection, imaging, scanning, and spectrometer with the support of high data rates in wireless transmission.
