Radio telemetry performance of liver implanted ultra wideband antenna

This paper considers a liver implanted antenna and its associated radio telemetric channel using ultra wideband (UWB) technology. The performance of both the implant antenna and the radio channel is evaluated numerically and experimentally using human equivalent multilayer phantom to obtain S-parameter results within the 4–8 GHz band for various distances between the implanted antenna and a body-worn one. The results show a strong potential in using UWB range for such wireless implant communication scenarios and for the intended applications.
