A textile antenna for WLAN applications

2009 International Conference on Emerging Trends in Electronic and Photonic Devices & Systems, 2009
A natural progression from the Personal Area Network (PAN) concept is the Body Area Network (BAN). A wearable antenna is an essential part of any Wireless BAN. A microstrip patch radiator is chosen as an example of low-profile wearable antenna, as it can be made conformal for integration into clothing.

Textile Antenna as Moisture Sensor

2020 14th European Conference on Antennas and Propagation (EuCAP), 2020
The paper proposes the application of a resonant textile antenna as moisture sensor. Two setups are discussed, the first considers the textile antenna used in transmission and the second considers only the reflection at the antenna input. Laboratory tests have been performed on both setups, showing that the second, reflection based, approach shows ...

Crumpling of PIFA Textile Antenna

IEEE Transactions on Antennas and Propagation, 2012
The performance of a PIFA textile antenna under different crumpling conditions is presented. The PIFA was designed for integration into clothing and other textile applications and the bending and crumpling conditions studied are typical of those found under normal use conditions both on and off body.

Flexible textile based antennas

Materials Technology, 2010
AbstractThe future generation of protective clothing will accommodate an entire sensor network to guard the health status of the professional during operation. Vital information can be of crucial importance to guarantee the physical safety of e.g. a fire fighter in full action.

UWB antennas on conductive textiles

2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016
Textile antennas fabricated using conductive E-threads are highly attractive for applications requiring conformality, flexibility, and robustness. However, most E-thread antennas reported to date operate at frequencies < 3 GHz. This is because of losses at higher frequencies, typically associated with surface roughness and imperfect metallization.

Logo antenna on textile materials

2014 44th European Microwave Conference, 2014
This paper presents a novel logo-shaped antenna. The proposed antenna has been fabricated by using a conductive non-woven textile on a layer of jeans. Experimental data referring to a prototype working at 1.8 GHz are presented and compared with numerical results. A relative bandwidth of about 70% and a dipole-like radiation pattern is demonstrated.

Textile PIFA antenna bending

2011 Loughborough Antennas & Propagation Conference, 2011
This paper presents the performance of a textile PIFA antenna under several bending and crumpling conditions. Input impedance, efficiency and radiation patterns are investigated based on numerical and experimental methods at 2.4 GHz.

Textile antennas: Effects of antenna bending on input matching and impedance bandwidth

2006 First European Conference on Antennas and Propagation, 2006
This paper describes how the performance of wearable textile antennas is affected on the antenna bending. Here, we will focus on the resonance frequency fluctuation and input-match bandwidth variation due to the antenna bending. The results are given for three different antennas, namely, a conventional patch, EBG, and dual-band U-slot antennas.

Implementation of conductive yarn into wearable textile antennas

2014 24th International Conference Radioelektronika, 2014
PIFA antennas and canonical microstrip antennas made of conductive yarn patterns embroidered into several clothing fabrics are investigated in ISM 2.4 band. The effect of lockstitch pattern onto the length of current path is studied for two conductive yarns of different mechanical properties.
