 Abstract —Implantable bioelectronics often relies on an RF-wireless link for communication and/or remote powering. Propagation through biological media is very lossy, and previous work has shown that these losses can be separated into three parts: the losses incurred by the propagating fields, the reflections at media interfaces, and the coupling of the reactive near field and the lossy body. The first two are unavoidable, but a clever antenna design can minimize the near-field losses. A good…
