Abstract: A novel mixed embroidered-woven coaxial-fed antenna based on a slotted short-circuited textile integrated waveguide has been designed, manufactured, and experimentally validated for its use in wireless applications. The structure of the antenna and the radiating slot can be manufactured using an industrial loom and a laser prototyping machine, respectively, whereas the conductive vias can be manufactured using a commercial embroidery machine, avoiding subsequent treatments or coating. The manufactured antenna presents a centralworking frequency of 5 GHz and a 20% bandwidth. Good agreement between simulations and measurements has been achieved. In addition, the performance of the antenna has been simulated and analyzed under bent conditions around an air-filled cylinder and using a phantom corresponding to a segment of an arm. This prototype demonstrates the possibility of implementing an alltextile antenna, reducing the backward radiation in comparison to the microstrip-based antennas by the use of a substrate-integrated waveguide topology.

A simulation model of electrical resistance applied in designing conductive woven fabrics
Yuanfang Zhao, Jiahui Tong, Chenxiao Yang, Yeuk-fei Chan and Li Li, “A simulation model of electrical resistance applied in designing conductive woven fabrics,” Textile Research Journal 86(16), Aug. 2018, doi: 10.1177/0040517515590408.
Abstract Numerous studies have performed analyses of knitted fabric integrating conductive yarn in textile-based electronic circuits, some of which established simulative models such as the resistive network model for knitting stitches. Compared to conductive knitted fabrics, limited studies have been presented regarding the resistive theoretical model of conductive woven fabric. In this paper, a simulation model was derived to compute the resistance of conductive woven fabric in terms of the following fabric parameters: structure, density and conductive yarn arrangement. The results revealed that the model is well fitted (P value<0.01) and can predict the resistance of woven fabrics, which makes it possible to estimate the fabric parameters and thus to meet the required resistance. Based on this model, thermal conductive woven fabric with maximum energy management and cost control can be efficiently designed.
