Dual Band Ingestible Antenna System for Wireless Capsule Endoscopy: Design Challenges
This paper aims to provide a comprehensive discussion on the challenges and key technologies associated with the design of capsule antenna systems. Furthermore, it proposes a compact CPW-fed dual-band capsule antenna system that integrates an interdigital structure and a parasitic radiator, enabling operation within the Industrial, Scientific, and Medical (ISM) bands for wireless capsule endoscopy. The functionality of the antenna is evaluated using a rat model. The simulated results demonstrate dual resonant frequencies at 0.82 GHz and 2.42 GHz, with corresponding gains of −18.7 dBi and −17.3 dBi, respectively.
