“…The theory already presented in the previous sections has been put into practice in different works developed by the authors. Partial results have already been presented in these works [34]- [38], not only verifying the theory underneath, but also justifying the necessity of the development and the analysis of these complex woven structures. The most representative results are summarized in the following subsections.…”

“…As a consequence, a first approach to study the behavior of conductive threads has already been introduced in [33]. Additionally, the authors have previously presented some partial results of the characterization and analysis of woven structures using simplified procedures in [34]- [38]. Finally, in this paper, a complete and enhanced parametric characterization and corresponding electromagnetic analysis are presented and validated using different examples.…”

This paper presents a complete and enhanced description of a parametric characterization and an electromagnetic analysis technique in order to simulate complex woven structures for the design of wearable microwave circuits and antennas based on smart textile. On the one hand, the parametric characterization consists of achieving the mathematical models which describe the different patterns conformed by the threads of the woven structures. This characterization takes into account the possible deformations of the materials inside the woven structure. On the other hand, the electromagnetic analysis technique consists of studying the conductive or dielectric parameters which describe the materials from which the threads have been extruded, and predicting the electromagnetic behavior of whole woven structures using the already explained parametric characterization. For this purpose, three different, although electromagnetically equivalent, models of the involved materials are needed, which subsequently reduce the computational resources required in the simulations. As a result, the woven structures can be characterized from the involved threads and the electromagnetic behavior can be analyzed in order to design wearable antennas or circuits.

“…Since the area of the RFID sensor chip is small, the size of the entire RFID sensor is determined by the size of the antenna. In order to study RFID sensors of small size, the use of textile technology to weave RFID sensors are introduced [80,81,82,83,84,85]. Textile integrated RFID has the advantages of low cost, durability, and the separation of textile and RFID chip manufacturing, making mass production fast.…”

Radio Frequency Identification (RFID) sensors, integrating the features of Wireless Information and Power Transfer (WIPT), object identification and energy efficient sensing capabilities, have been considered a new paradigm of sensing and communication for the futuristic information systems. RFID sensor tags featuring contactless sensing, wireless information transfer, wireless powered, light weight, non-line-of-sight transmission, flexible and pasteable are a critical enabling technology for future Internet-of-Things (IoT) applications, such as manufacturing, logistics, healthcare, agriculture and food. They have attracted numerous research efforts due to their innovative potential in the various application fields. However, there has been a gap between the in-lab investigations and the practical IoT application scenarios, which has motivated this survey of this research to identify the promising enabling techniques and the underlying challenges. This study aims to provide an exhaustive review on the state-of-art RFID sensor technologies from the system implementation perspective by focusing on the fundamental RF energy harvesting theories, the recent technical progresses and commercial solutions, innovative applications and some RFID sensor based IoT solutions, identify the underlying technological challenges at the time being, and give the future research trends and promising application fields in the rich sensing applications of the forthcoming IoT era.

This paper reports on very efficient and highly miniaturized wideband Polygon shaped Frequency Selective Surface (PFSS) shields for planar and conformal applications in X band. These shields have been analyzed for both lossy as well as for low loss substrates. The conformal configurations of PFSS are particularly investigated for inward, outward and double curved profiles useful for a variety of applications. The conformal designs have been tested for two different radii of curvatures. The models have been simulated using a hybrid simulation approach for electrically large geometries. Equivalent circuit model as well as analytical model is determined. The proposed PFSS designs offer stable angular response up to 60 0 for planar and all conformal geometries on both lossy and low loss prototypes. Shielding effectiveness of at least 55 dB and 48 dB has been measured for flat/non conformal and conformal configurations.
