Breast cancer detection using compact defected ground structure (DGS) ring resonator

This paper introduces a new, cost-effective and compact DGS ring resonator for breast cancer detection, it was designed and fabricated with a size of 15 mm × 15 mm, it was fabricated on a Roger 4003 substrate, a model of a breast with 10 mm × 10 mm × 3 mm tumor was created using CST Microwave studio, the detection process depends on the essentials of electrical material properties that the existence of tumor lead to shifting in resonant frequency. From the simulation results shifting in resonant frequency used for constructing a 29×29 matrix with 841 pixels, this matrix converted to a 2D image for the breast with tumor tissue, this 2D image identifies clearly the existence of the tumor.
