STUDY OF NOVEL MINIATURIZED IMPLANTABLE AND INGESTIBLE ANTENNAS FOR BIOMEDICAL APPLICATIONS

Abstract

Biomedical telemetry systems have received a considerable amount of attention recently. Antennas for implantable and ingestible medical devices (IIMDs) permit wireless transmission of physiological information continuously, from internal to external units, or treatment signals from the outside to internal devices at a distance. Wireless IIMDs are capable of performing healthcare functions for diagnosis, therapy, and monitoring. This thesis presents a comprehensive study of implantable and ingestible antennas for biomedical applications. The antennas presented in this thesis meet several demands that have not been carefully addressed. A circularly polarized implantable antenna, intended to realize a multi-platform operation, and a dual-polarization conformal antenna for endoscopy capsules are proposed. Moreover, to fulfill the dual-band requirements, both the single-fed implantable antenna and the differentially-fed one have been studied. Above all, the antennas developed in this thesis display the properties of compact size, low profile and conformability, aimed at providing a less invasive implantation experience.
