Abstract
Nowadays, RF biomedical telemetry systems are facilitated by the continuously increasing advancements in wireless communications, standards, and components. Wireless medical devices and, thus, antennas integrated into them can be divided into three categories, according to their placement on or inside the patient's body: (1) on-body, (2) implantable, and (3) ingestible antennas. Before the widespread use of on-body, implantable, and ingestible antennas, however, there are a number of technical challenges that need to be addressed, mainly in terms of design and channel modeling. Antennas are essential parts of RF biomedical telemetry systems, with their complexity highly depending on the surrounding tissue environment, and the electronics, communications, and medical requirements. This chapter overviews the challenges for on-body, implantable, and ingestible antennas, along with solutions proposed so far in the literature.
