SAR in the presence of conductive medical implant at 0.9, 1.8 and 2.4 GHz due to close proximity antenna

This paper evaluates the interaction between the human body and dipole antenna in the presence of conductive medical implant. A Voxel body model is exposed to the radiation source at three different frequencies; 0.9 GHz, 1.8 GHz and 2.4 GHz. A conductive bone plate is implanted inside the Voxel body in order to investigate the effect of medical implant on the Specific Absorption Rate (SAR). Results show that the inclusion of bone plate inside the body enhances the 10g SAR in the leg by more than 3 times. Besides, SAR and current density are remarkably enhanced in the adjacent tissue near the sharp edge of the bone plate. The simulated results are validated through measurement at 2.4 GHz.
