Wireless capsule endoscopy provides visualization of the GI tract by transmitting images wirelessly from a disposable capsule to a data recorder worn by the patient. The first capsule model for the small intestine was developed by Given Imaging and approved in Western countries and approved by the Food and Drug Administration (FDA) in 2001. Over subsequent years, this technology has been refined to provide superior resolution, increased battery life, and capabilities to view different parts of the GI tract. Before the introduction of capsule endoscopy (CE) and double-balloon endoscopy (DBE) , there was no effective modality for the evaluation and management of patients with obscure GI bleeding. Obscure GI bleeding is defined as bleeding of unknown origin that persists or recurs after a negative initial or primary endoscopy (colonoscopy or upper endoscopy) result. The first capsule endoscope model, which is now regarded as a first-line tool for the detection of abnormalities of the small bowel, was the PillCam SB. Our project aims to increase the speed of transmission and optimise the antenna to work within the permissible SAR limits as specified by the FCC.

Ultra-Wideband (UWB), compact antenna, Endoscopy.

This paper explains the working of the capsule endoscopy and the process of finding out how the antenna works in different conditions due to being ingested in the human body. In HFSS, the patch of the antenna was placed within different shaped models representing the organs in the GI tract and the different layers of human tissues such as muscle. During the simulation of the patch, some results showed that simulations as expected for biomedical application.
