A novel tree-slotted metamaterial terahertz antenna to diagnose breast cancer cells

In recent days, breast cancer is one of the most prevalent forms, and it necessitates timely identification to provide effective treatment. The present research proposed an innovative approach for detecting tumours in humanoid breast tissue with a metamaterial-persuaded THz patch antenna. THz antennas play a substantial part in various applications, including the medical domain. This paper presents the novel tree-slotted metamaterial (TSM) patch antenna, which resonates in the frequency band of 2.04 THz. The proposed structures are designed and simulated using the CST tool. Further, the breast phantom is modeled with the proposed patch antenna and the antenna characteristics are evaluated for different tumor sizes in the phantom. The proposed TSM antenna produces excellent results like − 62.35 dB return loss, 8.734 dBi gain and 1.0015 VSWR while detecting the 25 mm tumour size. Based on current THz spectrum research, this proposed antenna is employed to detect breast cancer cells as a primary cancer surveillance system.
