Any wireless communication between implantable antenna and an external off-body antenna suffers significant link loss due to the lossy nature of living human tissues. This link degradation is normally unpredictable and varies for different parts of the human body. To study an implantable communication scenario, complete setup is generally simulated using a full wave electromagnetic simulator. Such simulation requires human body phantoms having electrical properties such as permittivity and bulk conductivity, or even mass density similar to that of real body tissues. It has been observed that geometry of such phantoms is usually chosen as simple as possible to decrease the required computational resources and the overall time for the completion of the simulation. It is difficult to predict how much error is expected when realistic phantom is replaced by such geometrically simpler phantom. This study focuses on a comparison of the usefulness of using realistic human body phantoms over geometrically simple body phantoms for through-body communication simulation. To study this comparison, an implantable antenna, placed inside a human stomach model, is set to communicate with an off-body antenna at Medical Implant Communication Service (MICS) band. Keeping the distance between implantable antenna and off-body antenna constant, the realistic human body phantom is then replaced by two types of layered body phantoms with different complexity. Results in the form of calculated s-parameters and phantom complexity metrics are further investigated to conclude the study.
