Performance Evaluation of a Wearable 2.45 GHz Planar Printed Meandering Monopole Textile Antenna on Flexible Substrates

Abstract

This paper presents a wearable planar printed meandering monopole textile antenna design having operating frequency of 2.4 – 2.45 GHz on 3 flexible substrate materials: Jeans, Leather and Cordura®. The printed elements have been designed by using a mender line technique to reduce the size of the antenna significantly than the proposed antennas of past literature. Antenna performance is analyzed for different bending conditions and Specific Absorption Rate (SAR) is evaluated when the antenna is in contact with human body using CST Microwave Studio. The compact design and miniature size of the antenna is suitable for easy integration in smart clothing for tracking, healthcare, security and other ISM applications.
