Design Considerations for Wearable Antennas

Anja Skrivervik, Zvonimir Sipus, Jovanche Trajkovikj, Benjamin Fuchs

With the development of generalized connectivity and the increased use of Body Area Networks, wearable antennas have become ubiquitous in the last decade. Their design presents a challenge, as they per definition are located at the interface between free s ...

Diminishing SAR for Wearable UHF Antennas

Anja Skrivervik, Jovanche Trajkovikj

This letter presents a study on the specific absorption rate (SAR) evaluation of UHF wearable antennas. A planar inverted-F antenna (PIFA) intended to operate in wireless body area networks (WBANs) is taken as an example for the investigation. The presence ...

Performance of UHF W-BAN antennas in a real environment scenario

Anja Skrivervik, Jean-François Zürcher, Jovanche Trajkovikj

This work presents performance of robust wearable antennas intended to operate in Wireless Body Area Networks (W-BAN) in UHF, TETRAPOL communication band, 380-400 MHz. We propose a Planar Inverted F Antenna (PIFA) as reliable antenna type for UHF W-BAN app ...

PDMS, A Robust Casing for Flexible W-BAN Antennas [EurAAP Corner]

Anja Skrivervik, Jean-François Zürcher, Jovanche Trajkovikj

This paper describes a new technology for the realization of soft, flexible, and robust antennas intended to operate in a harsh environment. One of the main characteristics of the proposed technology is the ease of fabricating antennas in a simple lab envi ...

Institute of Electrical and Electronics Engineers2013

There has been a huge increase in interest for wearable communication devices in the last ten years. Applications are manifold, ranging from rescue to fashion over medical devices and safety, leading to the definition of new standards for Body Area Network ...

Design and analysis of planar UHF wearable antenna

Anja Skrivervik, Jovanche Trajkovikj

Slotted PIFA on the textile substrate suitable for body-centric applications in the UHF band is proposed. The influence of slot in the ground plane on the antenna parameters is theoretically investigated using simplified model of human body. © 2012 IEEE. ...

Soft and Flexible Antennas on Permittivity Adjustable PDMS Substrates

Anja Skrivervik, Jean-François Zürcher, Jovanche Trajkovikj

This work presents novel techniques for producing substrates for flexible antennas. The technique we propose is based on the use of an already existing and widely used substrate material Polydimethylsiloxane (PDMS), where the dielectric properties of the s ...
