An implanted antenna system for the monitoring of the healing of bone fractures

An implanted antenna system consisting of two monopoles attached on a metal plate for the monitoring of the healing of bone fractures has been investigated. The proposed structure has been simulated on a three layer body phantom model and the S2i response of the system is evaluated as the bone fracture that is introduced in the phantom gradually heals turning from blood to bone marrow and bone cortical in five discrete steps.
