Designing a Meanderline-Based Ultraminiature Low-Profile Ultrawideband Antenna for Biomedical Applications

This paper presents a customized ingestible and implantable antenna, utilizing a meanderline based design that has been specially engineered for wireless Ultra-wideband (UWB) endoscopy systems which can be used for different biomedical applications like microwave imaging, biomedical sensing and wireless power transfer (WPT) applications. The antenna exhibits a compact physical profile, measuring just 22×10×0.05 mm³. We investigate the performance of the capsule antenna within different organs of the digestive tract by employing a 3D human body voxel model in the CST Microwave Studio simulator. The omnidirectional radiation patterns exhibited by this design make it an ideal candidate for facilitating endoscopy communication. Notably, this antenna finds applications in a wide range of frequencies, including industrial, scientific, and medical (ISM) at 868.0–868.8 MHz,0.915 GHz,2.45 GHz and 5.7 GHz, wireless medical telemetry services (WMTS) at 1.4 GHz and the UWB spectrum spanning from 3.1 to 10.6 GHz.
