Multilayered Metamaterial Antenna for Brain Stroke Imaging System

This paper proposes a microwave-based brain stroke imaging system. A monopole patch antenna is loaded with metamaterials (MTM) surfaces to improve the gain required for stroke detection. A simulated configuration is described and analyzed in this work. The proposed system's performance is demonstrated upon placing an array of four element near human head tissue for hemorrhage detection and analysis. The proposed antenna's practicality is established via simulations using a realistic head model by examining the scattering characteristics as well as the Electric (E) and magnetic (H) field distributions inside the head. The reconstructed images show the potential of the conceptual model as a portable platform for efficiently detecting and locating hemorrhages inside the brain using the extracted field distributions.
