Two small antipodal Vivaldi antennas for ultrawide band early breast cancer detection are proposed. The antennas are designed to operate in the spectrum from 1 to 10 GHz, according to the requirements of wave penetration in the breast and imaging resolution. Simulated and measured reflection parameters of the proposed antennas are evaluated. Numerical results also show the proposed antennas have good near‐field radiation performance. Finally, an antenna array consisting of eight antipodal Vivaldi antennas, appropriate to collect the tumor scattering signal in the breast is presented. © 2012 Wiley Periodicals, Inc.
