Abstract :
The contrast in dielectric properties between normal breast tissues and malignant tumors is significant. Based on this fact, detection of breast cancer with microwaves has been proposed. Here, a cross-Vivaldi antenna capable of measuring cross-polarization is investigated for tumor detection. Observation of cross-polarized reflections reduces reflections from surfaces such as skin, permitting more reliable detection of small tumors. Simulation results indicate that the antenna has the potential to detect breast tumors using this approach
