Triple Band Printed Wearable Antenna for Remote Healthcare Monitoring Device

In the modern era, the role of antennas has grown dramatically high, especially in biological applications. Because of its size, compactness, non-invasive nature, safety, and cheaper cost, wearable antennas are utilized in numerous industries, including healthcare and Internet of Things (IoT). Additionally, wireless technology and wearable remote monitoring systems are essential methods for healthcare without sacrificing the life. In this paper, a low-profile antenna with Coplanar Waveguide (CPW) feeding technique is designed to operate at three frequencies 2.2GHz/4.2GHz/6GHz in wireless local area networks (WLAN), Worldwide Interoperability for Microwave Access (WiMAX), and Bluetooth for remote monitoring. Three resonant frequencies are produced using split-ring resonators with a circular shape antenna. To make a wearable antenna for patient monitoring, the proposed antenna is fabricated with a PREPERM paper substrate. This substrate, which is from PREMIX group, has a dielectric constant of 3.55 and a loss tangent of 0.005. The proposed antenna is studied based on parameters such as voltage standing wave ratio (VSWR), radiation patterns, return loss (S11) and gain. For antenna design, simulation and analysis, High-Frequency Structure Simulator (HFSS) software has been used.
