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 for on-body sensors

2015 IEEE Sensors Applications Symposium (SAS), 2015
Guidelines for modification of conventional antenna design to yield efficient operation in body-centric environment are presented. The interaction of the antenna and human body is investigated by modeling the wave propagation around torso. Two types of wearable antennas based on modifying quarter-wavelength shorted patch are designed and manufactured ...

Textile Wearable Antenna for Firefighters Positioning

2019 URSI Asia-Pacific Radio Science Conference (AP-RASC), 2019
This paper presents a fully-textile wearable antenna for pinpointing the location of firefighters in emergency scenarios. The proposed antenna is an aperture coupled microstrip antenna which mimics the coat of arms of the fire brigade of Lecce (Italy).

Jeans Textile Antenna for Smart Wearable Antenna

2018 12th International Symposium on Antennas, Propagation and EM Theory (ISAPE), 2018
This paper proposes a design of a dual band textile wearable antenna with miniaturized structure. The textile wearable antenna is designed at ISM band(2.45GHz and 5.8GHz). Choose denim material and copper tape as antenna substrate and radiating element, respectively.

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.

Wideband textile slot antenna array

2013 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2013
Wideband textile slot antennas have been developed with high precision. The antennas are composed of three textile layers: the top and bottom are conducting layers and are precisely defined by a laser cutting machine, while the third layer is a textile dielectric layer and sandwiched between these two conducting layers.

Washable Screen Printed Textile Antennas

Advances in Science and Technology, 2012
The wireless communication systems are applied in different applications such as computers, mobile phones, satellites and antennas for off-body communication. A lot of efforts were made to have the antennas in a smaller size, flat and with better performance. In the last decade the rigid antennas are replaced with textile in order to be flexible and to

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.

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 ...
