Abstract

This article presents the design and simulation of a small, high-gain circular patch antenna specifically for an implantable biotelemetry application. The antenna is constructed on a Rogers RT/Duroid 6010/6010LM™ substrate, 1.27 mm in thickness, including 0.035 mm circular radiating patches, as well as a ground plane. The antenna is tiny, with a patch radius of 14 mm, and the total volume of the antenna is 825 mm³. The reduced size creates a more efficient radiation pattern, and the substrate material is high in dielectric constant (ε_r = 10.2), allowing for a smaller size without sacrificing performance. Our suggested work introduces a novel solution to the given problems and presents a compact multi-band implantable antenna for implantable medical devices, which are used in the wireless medical telemetry service (WMTS) (1395-1400 MHz), medical body area network (MBAN) (2360-2400 MHz), lower ultra-wide band (UWB-L) (3100-4800 MHz), and upper ultra-wide band (UWB-U) (4800-10600 MHz) frequency bands. The proposed antenna design intends to enhance bandwidth, efficiency, and radiation pattern, all while remaining within strict size limits and biocompatibility requirements of implantable medical devices by carrying out widespread simulation and experimental verification.
