A Flexible Wearable Antenna for Wireless Body Area Network Application

In this paper, a flexible antenna working in the industrial scientific and medical band is introduced as a potential candidate for wireless body area network application. The antenna is fabricated using Polyethylene Terephthalate substrate which is flexible and easily available. The antenna is simulated in free space and near the human body. And subsequently, its characteristics are measured. The antenna operates in the ISM band for both the body and free space applications. The antenna has good gain in free space and in the proximity of human body. This makes it suitable for applications like wireless body area network and remote monitoring of patients.
