Breast cancer continues to be a predominant cause of mortality among women, with early detection playing a crucial role in enhancing the survival rates. This study introduces a textile jean-based ultrawideband (UWB) microstrip patch antenna, specifically engineered for breast cancer detection within the 3.1–10.6 GHz frequency range. The antenna, constructed on a 50 mm × 80 mm × 1.6 mm substrate, was simulated across various breast tissue models, ranging from tumor-free to complex structures containing tumors of diverse sizes and locations. The performance was evaluated using parameters such as the return loss (S11), specific voltage standing wave ratio (VSWR), and the absorption rate (SAR). The proposed antenna showed SAR values ranging from 1.6 to 2 W/g, which ensures its safety for use in medical applications, and it achieved a VSWR between 1.0 and 2 and return losses ranging from –30.0 to –18.5 dB. The flexibility assessment confirmed the suitability of the proposed sensor for wearable applications, underscoring its significant potential for the early detection of breast cancer
