Experimental active antenna measurement setup for UWB breast cancer detection

Abstract

Imaging by microwave UWB radar represents a promising technique for early-stage breast cancer detection. We present an experimental measurement setup for breast phantom trials based on M-sequence radar technology and active small antennas (interfacial dipoles). This approach combines short impulse responses, sufficient fidelity and very small antenna dimensions and allows for array construction with an adequate number of antennas around the breast. The presented imaging results illustrate the performance of the method.
