Textile antennas, a practical approach
نویسندگان
چکیده
Within the framework of the development of a wearable communications system for a sportsman, a textile antenna has been realised. The required antenna needed to be low profile, washable, insensitive to the proximity of the human skin and relatively insensitive to deformation. To overcome the human operator coupling effects on the antenna input impedance, i.e. a shift in resonance frequency and an increase of return loss level, a practical approach has been chosen. This approach consists of designing an antenna in free space, well matched over a wide frequency band. Because of the requirements and design methodology, chosen was for a (Log Periodic) Folded Dipole Array ((LP)FDA) antenna. Design equations for the antenna are discussed, measurement results of prototype antennas are shown and additional measures to tune the input impedance of the antenna are discussed.

Colorful Textile Antennas Integrated into Embroidered Logos
We present a new methodology to create colorful textile antennas that can be embroidered within logos or other aesthetic shapes. Conductive threads (e-threads) have already been used in former embroidery unicolor approaches as attributed to the corresponding conductive material, viz. silver or copper. But so far, they have not been adapted to ‘print’ colorful textile antennas. For the first tim...

The integration of the antenna and textile materials is very important in the army protective or data transmission clothing. In this study, a novel microstrip antenna integrated into a 3D orthogonal woven fabric was successfully designed and fabricated. This type of antenna is designed to work in wearable or conformal antenna applications. Simulation work using HFSS software was done for the de...

متن کاملPlanar Textile Antenna for Body Centric Wireless Communication System
One of the most important aspects for body centric communication is the development of the textile antenna for on-body communication. Antennas for on-body environment usually suffer performance degradation caused by the human body. Apart from that, textile antenna gets easily bent, flexed, wrinkled or wet. This paper presents an investigation on three different designs and types of planar anten...
