Studying Electromagnetic field pattern for Breast Cancer Detection by Hexagonal Patch Antenna

Cancer describes the cellular changes which lead to an uncontrolled division or growth of cells. Some types of cancer show visible growth of cells referred to as tumors. Every year hundreds of people are diagnosed with one or the other form of cancer with breast cancer as the most common type in females. This demands early detection, for which microwave imaging is considered to be the most promising method. A lot of contribution has been made in this field with materials having different permittivity and conductivity. In this paper, a 3-D structure of breast and microstrip patch antenna of hexagonal shape, operated at 2.45 GHz is designed using finite element method (FEM) in HFSS 15.0 with FR4 epoxy as a substrate to measure electromagnetic field patterns. The tumor present in breast is detected by observing Electric field patterns and specific absorption rate (SAR).
