A UWB antenna in direct breast contact for cancer detection

In this paper, a Ultra-Wide-Band (UWB) antenna of dimensions 3cm × 3cm, designed to be used in direct contact with the breast is presented. The breast phantom model, on which the antenna was designed, consists of four layers (skin, fat, glandular tissues and muscle with their specific thicknesses) taking into account the dielectric properties for each layer and their dependence versus frequency. The antenna has been optimized for many reasons: enhance the matching to the human body and maximize the transfer of energy into the breast phantom to increase the detection potential.
