Design and Realization of an Antipodal Vivaldi Antenna applied to Microwave Imaging for Early Breast Cancer Detection.

Antipodal Vivaldi antennas hold significant importance in medical applications, particularly in the field of microwave imaging, due to their wideband characteristics and efficient radiation properties. These antennas have shown promising results, enabling precise tumor localization and characterization in breast cancer detection, thus facilitating early diagnosis and improving patient outcomes (vers la conclusion). This paper presents the development of a prototype antipodal antenna through a meticulous process that involved using an electromagnetic solver that utilizes the Finite Element Method (FEM) for conceptualization and subsequent realization of the proposed antenna. Rigorous testing in our laboratory has demonstrated auspicious and concrete results, showcasing the antenna's exceptional performance in terms of radiation patterns and efficacy in the Ultra-Wide Band (UWB) frequency region. Furthermore, we found a strong correlation between the simulated and measured values of the reflection coefficients (S11), validating the accuracy and reliability of our design approach. These findings mark substantial progress in our pursuit of developing a low-cost imaging system for early breast cancer detection. [ABSTRACT FROM AUTHOR]
