Biocompatible Low-Cost Antennas Over Flexible Substrates for IoT-Health Applications

This paper presents a 10 GHz wearable antenna specifically designed for IoT-Health applications. Their main distinguishing features are its biocompatibility and flexibility, which are acquired by designing custom-made materials. Four custommade materials were designed and manufactured in order to compare the performance of the antenna according to the selected substrate. The study assesses the impact of these materials on critical parameters such as bandwidth, efficiency, and radiation patterns. This work includes both the simulations of the antenna behaviour based on the dielectric properties of the materials, and also the experimental results from the real measurements performed on manufactured antennas. Results contribute to the ongoing evolution of materials in antenna design, opening new possibilities for the advancement of communication solutions in healthcare applications.
