A cornered shallow cavity backed slot antenna suitable for smart hip implants

A hip implant can be equipped with sensors and microelectronics forming a wireless communication link between the implant and an on-body sensor to collect continuous data or provide real-time feedback. Since the implant is positioned in a heavily RF hostile environment, the antenna is one of the most critical parts of the system design. Here, an antenna to be located on a femoral stem is presented as well as an onbody sensor antenna completing the RF link. Initial simulations demonstrate promising results with good link quality.
