Design considerations for implantable and wearable antennas

This contribution gives a review of our results characterizing the propagation in lossy biological tissues. These results were mainly obtained using a simplified spherical model allowing a description in spherical wave decomposition. This model is of course simple, but has the advantage of providing rapidly a deep insight in the main loss mechanisms linked to implanted or wearable antennas, and thus derive efficient design rules for BAN antennas.
