摘要

Breast cancer continues to pose a significant health challenge, highlighting the need for advanced diagnostic technologies to improve treatment outcomes. This paper presents a novel approach for tumor detection in human breast tissue using a graphene-integrated terahertz (THz) patch antenna. THz antennas are crucial in medical diagnostics due to their unique properties, and the proposed star-shaped graphene-integrated antenna operates at a resonant frequency of 4.16 THz. The antenna, with dimensions of \(\ 114 \times 100 \times 26\) \(\upmu \text {m}^3\) is designed on a polyimide substrate, characterized by a dielectric constant of 3.5 and a loss tangent of 0.0027. Simulations carried out in Computer Simulation Technology (CST) studio software show that the antenna demonstrates strong performance, with a return loss of \(-\) 51.29 dB, a gain of 5.64 dBi, a bandwidth of 3.7 GHz, and a Voltage Standing Wave Ratio (VSWR) of 1.005. By exploiting the potential of the THz spectrum, the proposed antenna shows promise as a valuable tool for early breast cancer detection.
