Microwave breast phantom measurements with a cavity‐backed Vivaldi antenna

Abstract

The authors design a cavity‐backed Vivaldi antenna (CBVA) for microwave breast measurements. The design criteria for the antenna is shaped by the requirements of the free‐space measurement scenario where the receiving and the transmitting antennas are rotated by a mechanical scanner. Later, the authors have performed various breast phantom measurements with the CBVA to reveal its feasibility for microwave tomography.
