A Novel Microwave Imaging Approach Using Rectangular Antenna with Complementary Split-Ring Resonator

This research addresses the significant issue of breast cancer affecting millions of women worldwide, emphasizing the critical role of early detection in successful treatment.Among various medical technologies, microwave imaging stands out as an efficient and user-friendly method for breast cancer detection, with the antenna being a key component.In this paper, a novel rectangular antenna embedded with a complementary split-ring resonator is proposed for breast cancer detection.The antenna is fabricated using a jean substrate with dimensions of 20 15 2 mm.Notably, the proposed antenna demonstrates a wide bandwidth ranging from 2 to 10 GHz.The study introduces the concept of Specific Absorption Ratio (SAR), a measure of how much energy breast tissue absorbs in watts per kilogram (W/kg).The segment aims to highlight the utility of maximum SAR values in identifying the position of tumors within the breast.Through analysis at different frequencies, such as 2.01 GHz and 5.88 GHz, the maximum SAR coordinates closely correspond to the tumor location (-0.75, -2, 0).This indicates that the maximum SAR value is higher in the breast phantom with a tumor compared to the breast without a tumor, showcasing the potential of the proposed antenna for accurate tumor localization.The designed antenna is not only fabricated but also measured.Its notable features include multiband operation, compact size, stable radiation pattern, and a gain exceeding 3.25 dBi across the entire resonating band.These attributes make the antenna well-suited for applications in breast cancer imaging and wireless body area networks (WBAN) within the ISM band.Overall, the presented research contributes to the advancement of microwave imaging technologies for early breast cancer detection and monitoring.
