Design & Simulation of Microstrip Patch Antenna for Identifying Breast Cancer.

Abstract

This thesis is titled Design & Simulation of Microstrip Patch Antenna for Identifying Breast Cancer. The most prevalent and potentially fatal disease among women is breast cancer. So it's critical to find cancerous tissue early in the diagnosing process. Most conventional methods for finding breast cancer, unfortunately, have some drawbacks. Thus, methods for microwave imaging (MWI) is created. The MWI method is quite thought-provoking and hopeful. In this book, we have try to implement the technique. We try to design a Rectangular patch antenna for the detection of tumor. The substrate we used was fr4 [FR stand for "Flame Retardant." 4 means fiber glass epoxy] (lossy ) which dielectric constant was 4.3. In this thesis I also design a breast phantom via Computer Simulation Technology Microwave Studio (CST-MWS) with and without tumor. The size of tumor was 5 mm. set the antenna was simulated and the return loss, the VSWR, Surface Current, SAR value have been changed -19.265db, 1.2443, 36.8166A/m,0.637174 to -18.874,1.257.37.01,0.67539 . Which shows that propose antenna can detect tumor
