A Novel Design Rectangular UWB Antenna Array for Microwave Breast Tumor Detection

Breast cancer has become a significant health problem for women. Early detection of breast cancer in women is critical for proper and effective treatment. Ultra-Wideband (UWB) Microwave imaging is a technique that used wide bandwidth electromagnetic signals to see through the internal structure of the breast. This paper introduces the novel design of circular and rectangular antenna array in ring configuration which operated at frequency 2 GHz - 11 GHz. The antenna is designed and simulated to detect the presence of a tumor. The analysis is done by comparing the E-field, H-field, Specific Absorption Rate (SAR) of antenna without/with a tumor. With ring configuration, each element of the antenna is directly faced to the breast phantom for better tumor detection. From the simulation results, the E-field and H-field are obtained for breast with tumor. The SAR obtained is around 1.3 W/Kg, and safe to be used on breast tumor detection.
