Design and analysis of resonator-coupled antenna sensors for cancerous tissue detection in breast

Proposed to detect benign cancers in the breast is a small UWB antenna. The antenna runs over a range of frequencies from 3.2 GHz - 6.7 GHz measuring 20 x 32 x 1.6 mm3 and featuring a circular resonator permitting omnidirectional radiation with a peak gain= 4.9 dB and radiation efficiency=89.4%. Developed to fit real-life settings, models of three types of breast phantoms—tumor-free, single-tumor, and dual-tumor configurations—each displaying unique dielectric properties for benign and malignant tissues—are shown. S-parameter data from these phantoms enables PCA to separate benign from malignant tissues. Studies on particular absorption rates (SAR) help to improve the phantom tumor location. This work aims to investigate non-invasive Breast Cancer detection utilizing small-sized UWB antennas via dielectric contrast analysis.
