Investigation of inductive and radiating energy harvesting for an implanted biotelemetry antenna

A coil is integrated inside an implanted antenna in order to support inductive charging. The implanted antenna has been designed for wireless data telemetry at 400 MHz region and radiating wireless charging at 915MHz. The antenna-coil system is embedded into a three-layer canonical model of human arm. In the inductive charging case an external transmitting coil is considered while in the radiating charging scenario a dipole is implemented. Several simulations are carried out for the antenna-coil system. While radiating charging seems to be more efficient, inductive charging can be used as a complimentary solution since they both can coexist.
