Performance analysis of an Ultra Wideband Antenna for Wireless Capsule Endoscopy

This paper proposes an Ultra Wideband Microstrip Patch Antenna for Wireless Capsule Endoscopy. An approximate model of the human gastrointestinal environment is designed with CST Microwave Studio, and the antenna is placed in the center. The antenna is small and bent in a fashion so that it can easily be accommodated inside a capsule. Ultra Wideband technology facilitates higher data rate, resulting in faster communication and high-quality images. Reflection Coefficient (S
₁₁
), SAR, radiation pattern and power consumption are studied.
