Download or read book Passive UHF RFID Tag Antenna Design Using Graphite based Conductive Papers written by Michael Kurz and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence of passive ultra-high frequency (UHF) radio-frequency identification (RFID) systems has led to the annual production of RFID tags in the billions. Two graphite-based solutions developed at the Limerick Pulp and Paper Research Centre (LPPRC) were identified as possible candidates to achieve a more environmentally conscious tag with less complex manufacturing methods compared to what is currently available on the market. These materials are almost entirely composed of carbon and can be formed onto a biodegradable paper substrate using relatively simple methods. The materials’ intrinsic properties are characterized and a simulation profile is created to aid in the design of an optimized tag antenna. Conductivities of 600 S/m and 39,000 S/m are measured for the two graphite-ink and exfoliated-graphite based papers, respectively. Anechoic chamber read range measurements are performed using a commercial RFID reader. Maximum theoretical read ranges for prototype tags built using graphite-ink and exfoliated-graphite based papers are found to be 2.26 m and 6.83 m, respectively. Comparison of graphite-based tag prototypes and a commercial tag suggests that they are suitable for applications where the benefits of manufacturability and bio-degradability outweigh the disadvantage of a large antenna footprint. Six total designs with varying read ranges, complexities, sizes, and materials are found.
Download or read book Multi dimensional Ultra high Frequency Passive Radio Frequency Identification Tag Antenna Designs written by Stefanie Alkistis Delichatsios and published by . This book was released on 2006 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we present the design, simulation, and empirical evaluation of two novel multi-dimensional ultra-high frequency (UHF) passive radio frequency identification (RFID) tag antennas, the Albano-Dipole antenna and the Albano-Patch antenna, that provide omnidirectional communication capabilities. The performance of a passive UHF RFID tag is highly dependent upon the tag's antenna design, the tag's placement on an item, the materials in the item, and the item's surrounding environment. The majority of existing commercial tag antennas are two-dimensional making the tags a) orientation-sensitive, working well in some directions and not at all in others, and b) susceptible to communication interference from the contents of the tagged object. The Albano antenna designs are three-dimensional, affording the tags to be minimally affected by object material while maintaining near omnidirectional performance. The Albano antenna designs provide significantly improved orientation insensitivity compared with existing widely deployed commercial tag antenna designs.

Available in PDF, EPUB and Kindle. Book excerpt: In this chapter, an introduction to RFID systems has been presented. The major components of a RFID system were defined and the role of each one was discussed. Then, the characteristics of a RFID system were described using electric field integral equations, the Friis transmission equation and effective apertures. The electric field integral equations showed how the backscattered fields were directly related to the load at the port of the RFID antenna. The Friis transmission line equation was used to clearly show what determines the max read range of a passive RFID tag. The discussion on antenna apertures revealed how in the best possible situation only half of the incident power from the reader can be used by the passive IC. The rest of the power is scattered into the region around the tag. Next, a design methodology for producing compact space-filling antennas was presented. This section was immediately followed by two examples showing this design process. The result of this chapter is an understanding of the fundamental and important concepts of RFID systems and a structured design process for producing compact, useful space-filling antennas for many different applications.

Download or read book Design and Optimization of Passive UHF RFID Tag Antenna for Mounting on Or Inside Material Layers written by Shuai Shao and published by . This book was released on 2015 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a first step, the effects of dielectric materials on an antenna's impedance match and radiation pattern are investigated. The detuning effect is quantified based on the theoretical frequency scaling and effective permittivity of a dielectric material of finite thickness. Using simple formulas, the operational range of a tag can be predicted without intensive full-wave simulations of different materials. Next, a spectral domain Green's function is applied to compute the antenna pattern when the tag is mounted on or inside a layered medium. The optimal placement of the tag is found based on the focusing effect that the material has on the gain pattern of the antenna. For tires, the steel ply in the sidewall of a tire looks like a periodic wire grating. The performance of an antenna placed close to a wire grating is predicted using Floquet theory. The results indicate that steel plies embedded in the tire can be utilized as a reflector to further focus the gain pattern and increase the read range of a tag. Using these design tools and theoretical analysis, several broadband RFID tag antennas are designed for multi-layered materials. A novel stretchable conductive textile (E-fiber) based tag antenna is also developed for placement in elastic materials. Prototype antennas are fabricated and embedded in a tire during the tire manufacturing process. Experimental results indicate that tags with the new antennas achieve significant improvement compared with commercially available tags.

This book was released on 2022-03-11 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: In internet of things (IoT) applications, wireless connectivity is a key factor, particularly those that need to be in transition, or where wired communication is not effective or practicable. For top-notch connectivity of the Narrowband IoT (NB-IoT) standard, the 900MHz frequency is generally used by most of the vendors. The radiation quality not only depends on the antenna geometry but on immediate surroundings. Additionally, the IoT product itself and the user of the product can strongly affect the resulting radiation pattern and other characteristics of the antenna. On the other hand, a suitable antenna should also have high efficiency and adequate bandwidth covering the desired frequency range. To take these effects into consideration, the whole IoT product must be included in the antenna simulations. Antenna Design for Narrowband IoT: Design, Analysis, and Applications provides the antenna design concept for narrowband internet of things applications, performs a detailed analysis of the antenna, and discusses the various antenna design concepts and structures. Covering a range of topics such as antenna design and antenna measurement systems, this book is ideal for industry professionals, research scholars, academicians, professors, and students.
