Breast Tissue Tumor Detection Using Microstrip Patch Antenna with Defected Ground Structure

This work proposes a slotted microstrip patch antenna with an inset feed and Defect Ground Structure (DGS).The goal is to develop a broadband antenna with high gain and use it to detect tumors in breast tissue.The proposed antenna is constructed using Roger-RT/5880 (3r¼2.2) as the substrate material for X-band applications with a resonant frequency of 10 GHz.The proposed design was simulated using the Finite Element Method (FEM).Bandwidth and gain results obtained were approximately 700 MHz and 8 dB; respectively.In addition, the position of the antenna relative to the breast phantom used was optimized to efficiently identify tumors with a minimum radius of 3 mm, taking into account specific safety aspects where the SAR values is less than 1.6 W/Kg for a 1g of cube-shaped tissue.
