Breast Cancer Detection Based Microwave Imaging Using Single Antipodal Vivaldi Antenna

This paper presents breast cancer detection based on microwave imaging using single antipodal Vivaldi antenna. The breast cancer detection system mainly consists of antipodal Vivaldi antenna, vector network analyzer, breast phantom, and rotation platform. The artificial breast phantom is fabricated by using gelatin-oil mixture technology as fat and cancerous cell. The difference for relative permittivity and conductivity between cancerous cell and normal tissue is around 4:1 and 6:1, respectively. The process of breast cancer detection and imaging are presented. The measured results show that the cancerous cell embedded inside the breast phantom can be detected. In addition, the graphical user interface (GUI) for creating the 2D MWI is developed using MATLAB.
