Abstract

Wearable antennas have used in a wide range of applications such as: wireless communications, real-time tracking and wireless medical applications. Those antennas have to be integrated into or mounted on clothing and have the stable antenna performances according to the movement of the body. Different particular applications require different antenna performances include: antenna shape, dimension, resonance frequency, gain, direction and radiation efficiency.

This project primarily examines impacts of shorting strategies on the antenna performances. The different shorting strategies are considered in this study include: full shorting wall and two shorting posts which use flexible textile materials to realize. For each shorting methods, we realized three antenna use shorting with silver fabric wall, shorting eyelets and shorting with embroidered wall.

This project also considers impact of different substrate parameter on antenna performances. There feeding techniques include: microstrip line feed, coaxial-line feed and proximity-couple feed, are also examined.

Studies also design the dual-band textile wearable antennas which are able to operate in two ISM bands: (2.4 – 2.5) GHz and (5.725 – 5.875) GHz. All of three antennas satisfy desired requirements.

Introduction

Wearable electronics have gained interest recently due to the wide range of healthcare, sports, security, and military application [1]. Wearable antenna is one of the most important component of wearable applications. By integrating the antenna into clothing, the antennas will be used effectively to a lot of purposes such as mobile communication, person tracking, patient monitoring (in hospital).

The objectives of this project is to apply the principle of RF engineering, antenna analysis and design into designing novel wearable textile antennas.
