Abstract
Microwave Non-Destructive Testing operates based on the principle of detecting variations in dielectric constants to characterize the internal structure of dielectric materials. Microwave scattering's ability to penetrate biological tissues and differentiate dielectric contrasts enables the detection of tumors within the human breast. In this research, breast tumor detection was performed using an Ultra-Wideband (UWB) antenna, specifically a Metamaterial-Corrugated Antipodal Vivaldi Antenna (MCAVA), operating within the 2–8 GHz frequency range. Materials with dielectric constant values equivalent to those of breast tissue and tumors were employed. Time-domain analysis of S-parameter data obtained from MCAVA antenna measurements reveals of tumor presence within breast tissue.
