Split ring resonator inspired THz antenna for breast cancer detection

Abstract

A circular split ring resonator inspired (THz) antenna for breast cancer detection is proposed in this paper. The proposed metamaterial antenna is made from a simple rectangular patch antenna loaded with a Circular Split Ring Resonator (CSRR) structure in the ground plane. The design equations for the CSRR along with its equivalent circuit and permittivity calculations are also discussed in this paper. The experimental technique for detection of tumor in human breast model are also offered in this paper. The proposed circular split ring resonator inspired antenna operates at 1.5 THz resonant frequency with the VSWR ≤ 1.5 along with 24.2 dBi of gain and 90% of efficiency. The proposed circular split ring resonator inspired (THz) antenna could be a suitable candidate for a breast cancer detection application.
