Abstract

This timely paper introduces a miniaturized dual band implantable antenna (volume of 21.53 mm3) to adapt C-Band 5G biotelemetry in wireless capsule endoscopy (WCE). Open-ended slots were engraved on a patch to tune the antenna efficiently. The antenna along with the battery, printed circuit board (PCB), camera, and data-management system was placed within a biocompatible polyvinyl alcohol capsule. This antenna was communicating with fractional bandwidths of 20.42% and 13.85% and realized gains of -24.08 dBi and -26.11 dBi up to 12 m and 6 m distances at 2.45 GHz and 4.55 GHz simulated within the human body phantom, respectively. The antenna system was fabricated and placed within a homogeneous human body model to verify its performance through in-vitro measurements. Proposed system shows the known best performance reported on wireless capsule endoscopic systems. Introduction of 5G facility in WCE biotelemetry is also a novel approach in this application to improve the quality of smart patient monitoring.
