A novel UWB compact elliptical-patch antenna for early detection of breast cancer in women with high mammographic density

Abstract

Microwave imaging is one of the emerging technologies for early detection of breast cancer among women having dense mammographic densities. One of the critical and valuable components of an accurate, effective and compact, involving minimum risk - microwave imaging system for early breast cancer detection is an ultra wideband (UWB) antenna. A novel, compact elliptical UWB microwave antenna is presented in this research article that might be suitable for early breast cancer detection. The simulation of antenna structure is carried out using HFSS13 FEM-based EM software. The simulation results yield better UWB response. The antenna structure provides a wide practical fractional bandwidth of more than 156%. A significant performance factor of the proposed antenna is its ability to provide sufficient gain level for short distance communication. Thus, the proposed antenna is a strong candidate for design and development of microwave imaging system for early detection of breast cancer among women with dense mammographic densities.
