Novel ingestible capsule antenna designs for medical monitoring and diagnostics

This paper presents novel antenna designs for electronic digestible capsule pill systems. In the first part, a novel conformal planar offset meandered dipole capsule antenna for medical diagnostics is presented. The antenna performance is evaluated by studying the impedance, radiation, polarization and return loss characteristics inside the human body model. A link budget is evaluated to ensure wireless telemetry. In the second part, a novel RFID bio-capsule tag for medical monitoring is presented. The tag performance is evaluated by studying the impedance, radiation pattern and power reflection coefficient characteristics. Finally, a scheme for potential batch fabrication of these capsule antennas is presented.
