Summary:
Breast cancer is a common form of cancer in both developing and developed countries and one of the main causes of death among women. Early detection is necessary for a high chance of successful treatment and long-term survival. In recent years, breast cancer detection using radar-based technologies has been considered a promising diagnosis method. However, experiments using radar-based technologies for early breast cancer detection could not be performed on a real human patient at the engineering departments where the electrical components including the antenna systems are mainly studied and investigated. Therefore, it is important to develop an alternative measurement method that is able to simulate a real human patient for the study of antenna-related components of radar-based technologies. Also, magnified scale models of the antennas undergoing testing are commonly used as alternative measurement solutions at laboratories. By using the scale-up model technique, the fabrication process of the phantom and the delicate parts of the antenna system such as the feeding point could become less difficult, resulting in a higher accuracy of measurement results. In this paper, a new composition for a x2 scale phantom simulating both cancer and glandular tissues for the replication of the dielectric properties of real human tissue in the UWB frequency band was presented. Both phantoms consist of 5 materials; water and silicon emulsion as the main composition; glycerine to control the slope of relative permittivity; sodium calcium for minor adjustments of electrical properties; and agar to solidify the phantom. Finally, the fabricated cancer phantom and glandular phantom have a tolerance range of 25-75 percent, meeting the requirement to be used for wide-band radar and electromagnetic experiments for medical applications.
