Implantable fractal dental antennas for low invasive biomedical devices

In this paper, we propose a novel antenna for teeth implanting, which may attach a low invasive biomedical device to monitor human beings´ health conditions. A Hilbert-based curve 3D folded antenna is designed on ceramic denture (Z_rO₂) in Medical Implant Communication Service (MICS) band. A miniature antenna whose total areas is less than 128 (mm²) is achieved, which is reduced by more than 70%. Designed parameters are investigated to implant in different configurations. From simulations, an omni-direction radiation pattern is obtained to alleviate the specific orientation dependence.
