In fact, IMDs are expected be integrated in the next wireless system generation, 5G. This paper studies the in-body communication link between a low profile wearable antenna and an implantable antenna. We assemble a time-domain setup, in order to study the link by transmitting a quadrature-phase shift keying (QPSK) signal. This is an important analysis in order to fully assess the performance and feasibility of such link. The error vector magnitude of the received symbols shows Normal distribution, as predicted by theory for white Gaussian noise channels. Additionally, we evaluate the communication between the same wearable device and two implants at the same time. The results suggest such link is feasible although with relative position limitations. In fact, further research is needed to maximize power transfer to the gateway and minimize the energy coupling between implants. ER -
