Performance Analysis of SSRR in High-Speed Terahertz Antenna for Biomedical Applications

Breast cancer is the most prevalent type of cancer causing 1 of 8 cancer diagnoses globally. In the year 2020, there were approximately 2.3 million newly diagnosed cases and 0.685 million deaths from this disease. In order to avoid these, it is mandatory to detect breast cancer in the early stage. In breast cancer detection, terahertz (THz) technology is a promising technology that will not affect the skin due to heavy radiation and offers enhanced breast detection capability. The proposed THz antenna is based on a square-shaped split ring resonator (SRR) which helps to detect the tumor in the breast of the woman. The proposed square SRR antenna resonates at 2 THz with a return loss of -66.55 dB as the maximum and a VSWR of 1.0005. The square SRR structure produced the maximum gain of 8.721 dBi with 8.734 dB directivity. The designed antenna is suitable for biomedical fields such as detecting tumors, body scanner, and various THz applications.
