A Review on Design, Analysis, and Application of Conformal Antennas for Capsule Endoscope

For human healthcare applications, radio frequency sensors that can be used inside the body are developing day by day. In this kind of sensor, an implantable antenna in a capsule endoscopy system is executed leading to communication with external equipment. For this case, these implantable circuits are growing famous in the biotelemetry field for which large bandwidth, and high gain, with compact configurations, are required in the lossy human tissue. This work presents the various state-of-the-art conformal antennas for capsule endoscopes, with a focus on introducing structures and outcomes achieved from the simulation/measurement process. As this paper is reporting the recent developments in the domain of capsule endoscopy, anyone reading this work will get general and up-to-date views regarding this concept.
