Design and Analysis of Wearable Antenna for Wireless Body Area Network

Abstract

The fast development of wearable low-power devices has increased the requirement of solutions for WBAN implementation. In addition to the need, to reduce the device's dimensions and improve power consumption, it is also important to work on developing flexible antenna's that may be integrated into a wide variety of applications. This paper is a study of wearable antenna design for wireless body area network applications. A literature review of existing wearable antennas is studied. A wearable antenna is designed with size optimization. The antenna is designed using ANSYS High Frequency Structural Simulator (HFSS) software. The designed antenna works at operating frequency of 2.45 GHz. A rectangular patch made up of copper is used as radiating patch and the ground is also made with copper. The substrate material used is bed sheet cotton with a relative permittivity of 3.27 and the loss tangent is 0.00786. The size of the antenna is 40mm∗34mm∗1.26mm. The properties such as gain directivity and VSWR are studied for the designed antenna. The properties are studied using the ANSYS HFSS software.
