Abstract:
Hospitals worldwide have implemented High Frequency (HF) Radio Frequency Identification (RFID) networks for supplies tracking in ER setting, in-patient identification, surgical instrument management, and other applications. Merging of Web, Near Filed Communication (NFC), and HF RFID technologies for their combined use in e-Health applications is a logical next step due to the wide availability of NFC-enabled smartphones. This article outlines some resulting security challenges. Tags are often compliant with multiple standards that operate in the same frequency range. For example, HF RFID tags have already been adopted for in-patient tracking, yet smartphone NFC reader apps can freely access data on those tags. While tag– or session–centered security protocols exist for some RFID standards (e.g. ISO/IEC 29167), no ISO security standard is currently available for HF RFID tags. In such systems, proper traffic characterization can lead to better understanding of operation under “normal” system state conditions and could potentially help to identify security breaches.

Abstract:
RFID (radio frequency identification) technology has gained popularity in a number of applications. Decreased cost of hardware components along with wide adoption of international RFID standards have led to the rise of this technology. One of the major factors associated with the implementation of RFID infrastructure is the cost of tags. RFID tags operating in the low frequency spectrum are widely used because they are the least expensive, but have a small implementation range. This paper presents an analysis of RFID performance across low frequency (LF), high frequency (HF), and ultra-high frequency (UHF) environments. The authors' evaluation is theoretical, using a passive-tag BFSA based simulation model that assumes 10 to 1,500 tags per reader and is created with OPNET Modeler 17. Ceteris paribus, the authors' results indicate that total census delay is lowest for UHF tags, while network throughput performance of LF tags is highest for large scale implementations of hundreds of tags in reader's range. A statistical analysis has been conducted on the findings for the three different sets.

Abstract:
HF-band radio-frequency identification (RFID) is a robust identification system that is rarely influenced by objects in the robot activity area or by illumination conditions. An HF-band RFID system is capable of facilitating a reasonably accurate and robust self-localization of indoor mobile robots. An RFID-based self-localization system for an indoor mobile robot requires prior knowledge of the map which contains the ID information and positions of the RFID tags used in the environment. Generally, the map of RFID tags is manually built. To reduce labor costs, the simultaneous localization and mapping (SLAM) technique is designed to localize the mobile robot and build a map of the RFID tags simultaneously. In this study, multiple HF-band RFID readers are installed on the bottom of an omnidirectional mobile robot and RFID tags are spread on the floor. Because the tag detection process of the HF-band RFID system does not follow a standard Gaussian distribution, extended Kalman filter- (EKF-) based landmark updates are unsuitable. This paper proposes a novel SLAM method for the indoor mobile robot with a non-Gaussian detection model, by using the particle smoother for the landmark mapping and particle filter for the self-localization of the mobile robot. The proposed SLAM method is evaluated through experiments with the HF-band RFID system which has the non-Gaussian detection model. Furthermore, the proposed SLAM method is also evaluated by a range and bearing sensor which has the standard Gaussian detection model. In particular, the proposed method is compared against two other SLAM methods: FastSLAM and SLAM methods utilize particle filter for both the landmark updating and robot self-localization. The experimental results show the validity and superiority of the proposed SLAM method.

Abstract:
A traditional Radio Frequency Identification (RFID) system only resolves collisions of multiple tags on the Medium Access Control (MAC) layer, discarding the signals of the physical layer. Recently different groups started to pay attention on slots with colliding RFID tag signals, and coping with collisions on the physical layer, however. We proposes that using C-means clustering algorithm to analyze signal constellations of two colliding tags responses, to recovery from collisions of two tags on the physical layer and decoding their ID information successfully. This design uses low frequency (LF) 125k Hz carrier wave, and is also suitable for high frequency (HF) communication situation. Additionally, an error performance analysis with different SNR is shown. Based on performance simulations results, we demonstrate this approach can resolve collisions of two tags effectively in a slot on the physical layer and get a lower error probability.

The general considerations to design a sensor interface for passive RFID tags are discussed. This way, power and timing constraints imposed by ISO/IEC 15693 and ISO/IEC 14443 standards to HF RFID tags are explored. A generic multisensor interface is proposed and a survey analysis on the most suitable analog-to-digital converters for passive RFID sensing applications is reported. The most appropriate converter type and architecture are suggested. At the end, a specific sensor interface for carbon nanotube gas sensors is proposed and a brief discussion about its implemented circuits and preliminary results is made.

Abstract:
We present measurements of spurious emission produced by high-frequency radio frequency identification (HF RFID) using carrier frequency of 13.56 MHz. HF RFID tags produce unwanted emission due to rectification and more generally due to nonlinearity of analog front end. Depending on the conducting material of an HF RFID coil and surrounding dielectric material, the coil behaves as more or less good antenna on some harmonic frequencies. Exact characterization and analysis of unwanted emission is important from the security perspective as well as from the perspective of interference with other systems. Consequently we measured the harmonics produced in the integrated circuitry and characterized radiation properties of the antenna. Finally we present the measurements of the spurious emission performed in a Gigahertz Transverse Electromagnetic (GTEM) cell.

Abstract:
Ces travaux examinent le potentiel d’un papier à fort lissé pour la production de masse de tags RFID-HF imprimés. Les caractérisations menées sur le papier Powercoat HD mettent en évidence une haute tolérance à la température et une faible rugosité. De fait, il se présente ainsi comme une sérieuse alternative à l’utilisation des films polymères (PET, PEN, PI, etc.), permettant de développer pleinement les performances électriques d’encres conductrices métalliques.Deux procédés d’impression industriels ont été considérés, la flexographie et la sérigraphie ayant tout deux fait leurs preuves depuis plusieurs décennies pour l’impression graphique à hautes cadences. Le potentiel de leur utilisation pour l’impression à grande échelle de dispositifs électroniques à bas-coût est discuté dans ces travaux. De plus, les performances électriques d’encres commerciales à base d’argent sont étudiées en fonction de la taille des particules qui les composent. En effet, l’utilisation de particules métalliques à l’échelle nanométrique pourra faciliter l’activation des mécanismes de diffusion atomique, améliorant ainsi le contact physique entre les particules et favorisant la conduction électrique. En parallèle, les encres à microparticules sont moins coûteuses et leurs conditions d’utilisation moins contraignantes. Toutefois, la coalescence des particules métalliques après l’impression ne pourra être initiée sans un traitement thermique de recuit.Le recuit est usuellement réalisé dans une étuve ou un tunnel à air chaud, la température doit alors rester inférieure à la tolérance du substrat. Cela permet d’atteindre des performances électriques qui restent limitées pour des durées de procédé de l’ordre de plusieurs minutes. Afin de tenir compte des contraintes industrielles d’une production à grande échelle et de permettre d’obtenir les meilleures performances électriques en un temps réduit, l’un des principaux axes de recherche exploré consiste au déploiement des technologies émergentes de recuit photonique proche infrarouge (NIR) et lumière intense pulsée (IPL). Ces dernières sont basées sur l’absorption de l’énergie lumineuse par le film d’encre provoquant ainsi sont échauffement rapide. L’important différentiel d’absorption entre les encres et le substrat contribue, en outre, à une sélectivité de ces procédés permettant de limiter la dégradation du support tout en atteignant au niveau de l’encre, des températures pouvant être supérieures à 300°C. Pour chaque procédé de recuit, l’influence des différents paramètres sur les performances électriques finales a pu être étudiée par la mise en place d’un suivi in-situ de la résistance, permettant un échantillonnage allant jusqu’à 250 kHz.Finalement, des boucles RFID-HF ont été imprimées, recuites dans les conditions précédemment optimisées puis caractérisées. Une estimation des coûts de production a été menée afin de distinguer les contributions liées à l’encre, au support et à la puce électronique en silicium. Les résultats obtenus mettent en évidence le potentiel du papier Powercoat HD, couplé à une impression en flexographie et à un recuit proche infrarouge, permettant alors la production à grande échelle de tags RFID-HF pour un coût matière de l’ordre de 5 centimes d’euros<br>This work examines the potential of a very smooth paper for the mass production of printed RFID-RF tags. Characterizations on Powercoat HD paper demonstrate high temperature tolerance and very low roughness. It thus represents a serious alternative to the use of polymeric films (PET, PEN, PI, etc.), enabling the electrical performance of metallic conductive inks to be fully developed.Two industrial printing processes have been considered, flexography and screen printing, and their use were discussed for the printing of low-cost electronic devices. Moreover, the electrical performances of commercial silver based inks are studied according to the size of their particles. Indeed, the use of metal particles at the nanometric scale can facilitate the activation of the atomic diffusion mechanisms, thus improving the physical contact between the particles and promoting electrical conduction. In parallel, microparticles inks are cheaper and their conditions of use less restrictive. In any case, the coalescence of the metal particles after printing cannot be initiated without a thermal sintering treatment.Sintering is usually carried out in an oven or hot air tunnel, the temperature must therefore remain below the tolerance of the substrate. This leads to limited electrical performances for long process duration of several minutes. In order to take into account the industrial constraints of large-scale production and to achieve the best electrical performance in a short time, one of the main explored research areas is the deployment of emerging near-infrared (NIR) and intense pulsed light (IPL) photonic technologies. These latter are based on the absorption of light energy by the ink film thus causing rapid heating. The important absorption differential between the inks and the substrate allows high heating selectivity which makes it possible to limit the degradation of the substrate while the ink temperatures may be greater than 300 ° C. For each sintering process, the influence of the various parameters on the final electrical performance has been studied by setting up an in-situ resistance monitoring, allowing sampling frequency up to 250 kHz.Finally, RFID-HF loops were printed, sintered under previously optimized conditions and then characterized. An estimate of the production costs was carried out in order to distinguish the contributions related to the ink, the substrate and the silicon chip. The obtained results demonstrate the potential of Powercoat HD paper, coupled with flexographic roll-to-roll printing and near-infrared technology, enabling the large-scale production of RFID-HF tags at a material cost of the order of 5 euros cents

Abstract:
The performance of commercial Radio Frequency Identification (RFID) tags is primarily limited by present techniques used for tag antenna design. Currently, industry techniques rely on identifying the RFID tag application (books, clothing, etc.) and then building antenna prototypes of different configurations in order to satisfy minimum read range requirements. However, these techniques inherently lack an electromagnetic basis and are unable to provide a low cost solution to the tag antenna design process. RFID tag performance characteristics (read-range, chip-antenna impedance matching, surrounding environment) can be very complex, and a thorough understanding of the RFID tag antenna design may be gained through an electromagnetic approach in order to reduce the tag antenna size and the overall cost of the RFID system. The research presented in this thesis addresses RFID tag antenna design process for passive RFID tags. With the growing number of applications (inventory, supply-chain, pharmaceuticals, etc), the proposed RFID antenna design process demonstrates procedures to design tag antennas for such applications. Electrical/geometrical properties of the antennas designed were investigated with the help of computer electromagnetic simulations in order to achieve optimal tag performance criteria such as read range, chip-impedance matching, antenna efficiency, etc. Experimental results were performed on the proposed antenna designs to compliment computer simulations and analytical modelling.

Abstract:
The concrete maturity method can be utilized to determine in situ strength of concrete. It uses the temperature of concrete to determine a maturity index that can then be used to determine strength of concrete. However, monitoring the concrete temperature using thermocouples brings up a wiring issue, which is not advisable in an equipment and human intensive area like a construction site. One of the ways to get around this wiring issue is to use Radio Frequency Identification (RFID) technology, which is capable of transmitting information wirelessly. Previous research implemented using ultra high frequency RFID tags embedded in fresh concrete found that water could be the impediment for transmitting RFID signal from within concrete during early stages of curing. From literature it was found that lower the frequency, better the chances of the wave penetrating water. The objective of the research was to figure out whether the frequency of RFID tags has any relationship with the readability of RFID tags embedded in fresh concrete. For this investigation, low frequency, high frequency, and ultra high frequency RFID tags were tested within fresh concrete to see any difference between tags in terms of transmitting information. This experiment was carried out in a controlled space to reduce the number of variables affecting the experiment outcome. The low frequency, high frequency, and ultra high frequency RFID tags were placed within 2 in x 3 in x 2 in wooden formwork at a depth of 4 in, 8 in, and 12 in. Ready mix concrete was poured into the formwork and 3 concrete cubes were cast with the tags embedded within them. Readers that could be connected to a laptop were used to monitor and collect the time at which these RFID tags can be detected. The test showed that the RFID signals from the low frequency tags at all depths were detected as soon as concrete was poured. The Ultra High Frequency tags placed at the 4" level could be detected 15 minutes after concrete was poured. The UHF tags at the 8" level could be detected after 30 minutes. The UHF tags at the 12" level took on an average 2 hours to be detected from the vicinity of the formwork. The greater the depth at which the ultra high frequency tag was buried the longer it took for it to be detected. The high frequency tags could be detected only at the 4" level. The reason the performance of the HF card degraded in concrete could be because it uses an aluminum foil antenna which is more susceptible to the environment changing the relative permeability. A copper wire antenna could have fared better in this condition, increasing the chances of detecting the tag. Moreover a passive tag was used. The read range and chances of detection could have been increased had an active tag been used. The power of the reader that was used was also very less which might have contributed to the tag not being detected. Among the tags that were used in the experiment it was found that low frequency tags was the tag that could be detected the earliest after concrete was poured into the forms. However, the maximum read range of the tag observed in the experiment was 20" which is too small a distance to be used on an actual construction site.

Abstract:
碩士<br>逢甲大學<br>產業研發碩士班<br>105<br>This study focuses on the design of compact HF and UHF RFID tag antenna. In order to verify the performance of antennas, there are three different types of RFID tag presented in this research. Basically, they are the HF-RFID (13.56 MHz) multilayer compact tag, a loop antenna for UHF-RFID (915MHz), and a dual-band tag that are integrated by HF-RFID and UHF-RFID. The first antennas have three types and can be applied in HF-RFID. The best design is multilayer compact tag, it consists of square coil inductor and three-layer substrate with four-layer coil overlap structure. The coil which uses via to conduct is designed in counterclockwise direction. The design with this combination can not only reduce the tag’s size,but also reach the design required inductance of tag chip (ST M24SR64-Y I^2C) at 13.56 MHz. The antenna was fabricated on a FR4 substrate which is composed of three 0.8 mm thick layers, with a relative permittivity of 4.4 and a loss tangent 0.02. It only occupies a volume of 19×19×1.4 mm^3. The reading distance of this tag is 35 mm through the use of Google Phone Nexus measurement at the frequency of 13.56 MHz . The second tag is applied in UHF band(915 MHz),which is intended to be integrated with tag. There are two types of antenna, loop antenna and dipole antenna, respectively. The loop antenna configuration uses a T-match impedance matching circuit and a meander-line structure. This method can effectively increase the antenna current path and adjust the impedance value. The total antenna area is 58 x 56 mm^2. Another antenna is a dipole structure. It also uses T-match impedance matching circuit and a bending symmetry architecture. It has a size of 37 x 27 mm^2. They are both fabricated on a FR4 substrate, with a thickness of 0.8 mm, a relative permittivity of 4.4 and a 0.02 loss tangent. With tag chip Higgs 4 IC impedance 8-j143 matching, both tags can be used at 915 MHz. They had been measured by Voyantic Tagformance, and have reading distance of 12.5 m and 4.4 m, respectively. The last design is a HF and UHF dual-band tag. The difficulty of the design is to integrate two different frequency bands on the same substrate. We choose loop antenna for UHF operation design, because its center area has enough space that can place the HF tag and less field influence. The antenna area is 58 x 55 mm^2. The HF band tag constructed by a multi-layer structure is designed inside the UHF tag . The HF antenna is a square coil inductance printed on the three-layer substrate and the size is only 19 × 19 × 2.4 mm^3,which is implemented on a three-layer FR4 substrate with a total thickness of 2.4 mm. Through the above measurement method, the reading distance is 33 mm at 13.56 MHz and 11 m at 915 MHz . The above tags can be used in the most popular communication bands of RFID today. The advantages of the designs are low cost and easy to manufacture. Especially, the dual-band integrated tag greatly enhances the convenience of RFID applications .

First, two designs of single and double-faced loop antennas for HF RFID tags are presented. Both of them give good performances in the reading range. Also, the double-faced tag antenna can achieve antenna size reduction. Next, the designs of UHF RFID tag antennas are proposed. The half-wavelength and quarter-wavelength slot antennas are applied to design UHF RFID tag antennas. Varying the shape of the slot miniaturizes the size of the antenna. A tuning section is used to adjust the input impedance of the slot antenna, and good impedance matching can be achieved. The quarter-wavelength slot antenna achieves more antenna size reduction.

At first, using electromagnetic software (IE3D) to simulate the return loss, radiation pattern and distribution currents is carried. The antenna measurement in the anechoic chamber is obtained to verify its performance with the radiation patterns. Consequently, by tuning pad and stub matching circuit in the design is used to tuning resonated frequencies, impedance character for matching. The simulation software of the circuit (ADS) is used for the matching LC circuits. The matching LC circuits can be applied to the HF/UHF microchips. It is a compact and available tag antenna for HF/UHF RFID positioning applications. For application, the card-type HF/UHF dual-band RFID tag antenna with Hilbert-curve loop presents, the S21 frequency responses with -3dB bandwidth 2.2MHz at HF-band, S11 frequency responses -10dB bandwidth 25MHz at UHF-band. The directivity gains are 1.78 dBi for HF-band(13.56 MHz) and 2.23 dBi for UHF-band(865 MHz). Radiator patterns of dipole antenna are presenter at broadside in the X-Y cut plane and quasi-omnidirectional patterns are obtained in the Y-Z cut plane. The total size is 50mm *35mm can be applied for cards.
