Propagation Considerations for Implantable Antennas

The use of Body Area Networks has been increasing in the past decade due to the emergence of novel wearable and implantable services in the frame of e.g. healthcare, sports, security or fashion. As a result, the number of wearable and implantable antenna designs has exponentially increased in the same time frame. After this first boom in research related to W-BAN antennas, it is now time to learn from the achieved results, and try to understand the mechanisms limiting the performances of such radiators, in order to finally be able to develop useful practical design rules. In this contribution, we introduce a theoretical analysis of some canonical implanted W-BAN electromagnetic source scenarios, using a specifically developed numerical tool based on spherical wave expansions. The obtained results are used to give some design criteria for implantable antennas.
