Study of implantable antenna for artificial knee joints

Antenna embedded into human body using a high-resolution artificial knee joints models was evaluated here. From this result, when the position of the implantable antenna is installed at nearly edge of the plastic spacer, implantable devices had better communication with Reader/Writer than at the center of plastic spacer. However, the impedance of the IC chip located in the antenna used this study was unknown. For that reason, the results of this study was not considered on loss due to mismatch. In the future, we will investigate the impedance of the IC chip and optimize the implantable antenna.
