Millimeter-Wave Dielectric Resonator Antenna for Breast Tumor Detection

A millimeter-Wave Dielectric Resonator Antenna (DRA) with aperture feed is designed for breast tumor detection, and operates at 33GHz frequency. The mmWave imaging technique is an alternative method for screening breast cancer that does not involve ionizing radiation. The mmWave imaging takes advantage of the dielectric discontinuities in tissues, including malignant lesions, to detect abnormalities. As millimeter waves interact with the breast tissue, variations in the dielectric characteristics can provide valuable information about the presence of tumors or other anomalies. In this work, cylindrical dielectric resonator antenna (CDRA) operating in the millimeter-wave frequency range is designed. The antenna to have an impedance bandwidth of 10.8% and a gain of 6.17dBi. The tumor in the breast can be detected by monitoring the changes in the antenna's S parameter.
