Wearable Penta-Patch Microstrip Antenna for Biomedical Applications

A portable antenna that can be incorporated into your clothes is a great solution to the issue of remote health monitoring for the elderly. This would allow the transmission and reception of sensor data without compromising the health and comfort of the elderly users. The objective of this research is to investigate the wear-and-tear characteristics of the antenna in real-world applications, as well as to address the design and manufacturing challenges associated with high-performance antennas fabricated on flexible textiles or rigid substrates. This project works on the designing of pentagonal patch microstrip antenna for Wi-Fi (2.4 GHz), ISM and Wearable Application. This research presents the antenna operates in the frequency band of 2.4 GHz and designed for two substrates such as FR4, and cotton. Unlike the FR4 with relative permittivity εr = 4.4, loss tangent tanδ = 0.002, and cotton, which has a dielectric constant (εr) of 1.51 and a loss tangent (tan δ) of 0.025. Conventional copper metal sheets have been employed as the conductive material for both the ground and the patch of the antenna. The CST software is used for the simulation of antenna design, and the obtained results indicate that the antenna utilizing cotton as a substrate is highly efficient in terms of gain, sensitive, and cost-effective, meeting the performance requirements for biomedical applications. Additionally, this wearable antenna can be directly attached to the human hand to effectively monitor relevant health parameters.
