Experimental phantom trials for UWB breast cancer detection

Electromagnetic ultra-wideband sensing and imaging provides perspectives for early-stage breast cancer detection. This paper deals with practical challenges of real measurements. We present an experimental setup for breast phantom trials based on M-sequence radar technology. In contrast to similar published works we apply electrically short antennas (bowtie dipoles). This approach combines short impulse responses, appropriate fidelity and very small antenna dimension and allows array construction with sufficient number of antennas around the breast. Obtained imaging results are presented and significant aspects are discussed.
