Effective Modeling of GBC Based Ultra-Wideband Patch Antenna for Brain Tumor Detection

This paper presents a special ultra-wideband (UWB) patch antenna using graphene based conductor (GBC) has been proposed to find human brain tumor. A UWB microstrip patch antenna is designed that consists of radiating element operating at a band from 3.15 – 9.15 GHz. Lengths of ground patch has been considered as the key parameter to achieve optimum antenna performance in terms of reflection coefficient (S11). To detect the brain tumor in human head, a six layered human head model is considered and the proposed antenna is located at 20 mm distance from human head. Brain tumor presence indicated by lower reflection coefficient values compared to higher values recorded by brain tumor absence. The biocompatibility analysis of the head tissue is determined using CST MWS software.
