Book Description
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.

Book Description
Radio Frequency IDentification (RFID) stores and retrieves data using devices called RFID tags: objects attached to or incorporated into a product, animal or person which communicate with an RFID reader or interrogator. This book proposes a linear two-port model for an N-stage modified-Greinacher full wave rectifier, predicting the overall conversion efficiency at low power levels where the diodes are operating near their threshold voltage. Included is an experimental procedure to measure how impedance modulation in the tag affects the signal at the reader, and a useful tool for choosing the most appropriate impedances.

Book Description
This book describes innovative design solutions for radio-frequency identification (RFID) tags and antennas. Focusing mainly on passive ultra-high-frequency (UHF)-RFID tag antennas, it examines novel approaches based on the use of metamaterial-inspired resonators and other resonant structures as radiating elements. It also offers an exhaustive analysis of the radiation properties of several metamaterial-inspired resonators such as the split ring resonator (SRR) and related structures. Further, it discusses in detail an innovative technology for the RFID tagging of optical discs, which has demonstrated a significant improvement over the state of the art and resulted in a patent. By covering the entire research cycle of theory, design/simulation and fabrication/evaluation of RFID tags and antennas, while also reporting on cutting-edge technologies, the book provides graduate students, researchers and practitioners alike with a comprehensive and timely overview of RFID systems, and a closer look at several radiating structures.

Book Description
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.

Book Description
"Radio frequency identification (RFID) has become one of the fastest growing wireless technologies. An RFID system is a real-time processor that enables the information stored on a tag to be tracked and exchanged remotely with an RFID reader. The RFID tag plays a critical role in determining the overall performance of the entire system, as well as its size, cost and detection range. In this thesis, various miniaturized RFID tag antennas are investigated and implemented for conventional and emerging passive ultra high frequency (UHF) RFID applications. First, the design and experimental evaluation of three compact printed tag antennas including folded, 2D and 3D meander monopoles are presented. Next, designing a new miniaturized tunable passive UHF RFID tag is undertaken with the operation frequency covering the entire range of the UHF RFID regulated bands (840-960 MHz). This design method not only can be used in tags targeting the global RFID market, but also is crucial for the successful implementation of an RFID system that is tolerant of detuning due to fabrication process variations and loading of deployment environment. As well, a low profile RFID tag consisting of a compact microstrip patch antenna backed by a mushroom-type Electromagnetic Band Gap (EBG) structure is proposed. This design which achieves an area reduction of 29.11% compared to a conventional patch yields a maximum reading range of around 11 m as a free standing tag and when attached to a metallic surface.To extend the reading range of the RFID tag, a solar panel is integrated with the patch antenna to boost the RFID chip's operating power. Furthermore, new aspects of antenna and RFID chip integration in multi-port/antenna arrangements are explored through the design and measurement of tag prototypes.RFID technology has recently been employed in sensor applications for low-cost low-power wireless sensor node implementation. This thesis also presents novel dual-port UHF RFID tag antennas for simultaneous wireless identification and sensor applications. Special RFID tag antennas are designed and integrated with passive resistive sensors demonstrating detection of sensor data by utilizing a commercial RFID reader. Finally, another RFID-tag-sensor for transmission of generic sensor data is implemented, which also includes solar energy harvesting. This design is further improved by employing a novel two-port patch antenna that collects the ambient RF energy through its second port. A reliable RFID communication range of up to 27 m was achieved in an indoor measurement scenario, which represents, to the author's knowledge, the longest distance ever reported for similar sensor-enhanced RFID tags." --

Book Description
"Radio frequency identification (RFID) is a means of remotely identifying objects through radio frequency communication. An RFID system provides a means to capture information inexpensively and accurately. This system allows real-time accessibility and delivery of object information, which helps track assets and shipments globally. A transponder integrated circuit (IC) is used for storing and retrieving information about a remote object. A passive RFID tag consists of an antenna and a radio frequency compatible transponder IC labeled, or attached, onto products for unique identification. This thesis deals with passive RFID tag antenna design and analysis of the read range performance of the tag on objects of different dielectric materials. Given the limits of the operating power of the transponder IC and the RFID reader transmitting power, the design issues are the read range of the tag, size of the tag, and impedance matching the tag antenna to the transponder IC. Also in this thesis a step-by-step process used to design a passive RFID tag is presented. Finally, the fundamental constraints of the design, and their associated tradeoffs, as well as measurements and analysis of the designed passive UHF RFID tag, are given"--Leaf iii.
