Design of a Compact Simple Structured Dual-band Patch Antenna for Wireless On-body Medical and Sports Devices

摘要

This paper targets to design a suitable on-body patch antenna at recommended frequency ranges for body-related communications. The Strongest key features of this antenna are its simplest structure, which will help to avoid fabrication complexity, compact size, dual-mode band and decent bandwidth (0.937GHz). The total volume of the antenna is only 338mm^{3. The antenna’s radiating patch and full-ground were created with copper, and low loss material ROGER R03006, having dielectric constant of 6.5 and loss tangent of 0.0035, was selected for the substrate. At on-body condition, the antenna’s resonance frequencies were recorded at 0.43306GHz ISM (Industrial, Scientific and Medical) band and 5.4899GHz Ultra-wideband. Throughout the study, several mandatory parametric analyses of the antenna through CST MICROWAVE STUDIO SUITE 2020 were done to be ensured that it is practically implementable in on-body devices.}
