Tidskriftsartikel (refereegranskat)abstract
- This paper presents performance optimized RFID tag antenna, developed by using commercially accessible paper substrates and advanced inkjet printing process to guarantee mechanical flexibility and ultra-low production costs. The proposed antenna structure can endure the variations which emerge in electromagnetic properties of paper substrate due to varying environmental effects. Hole-matching technique is implemented to eliminate the matching network for reducing the consumption of conductive ink. The proposed structure is uniquely evaluated by demonstrating, sustainability and environmental impact analysis that validate the potential for ultra-low cost mass production of RFID tags for future generation of organic electronics. The antenna performance is assessed for cardboard cartons exclusively containing metal cans and water bottles. The experimental characterization of the proposed antenna endorses the wider bandwidth to cover UHF RFID ISM band (860-960MHz), which empowers its usage throughout the globe for supply chain applications. The improved design effectuates return loss of better than -15dB over a wide frequency range while exhibiting outstanding readability from 10.1 meters.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In the recent years, radio-frequency identification (RFID) technology has been widely integrated into modern society applications, ranging from barcode successor to retail supply chain, remote monitoring, detection and healthcare, for instance. In general, an RFID tag or transponder is composed of an antenna and an application-specific integrated circuit chip. In a passive UHF RFID system (which is the focus of presented research), the communication between the transponder tag and the reader is established by modulating the radar cross section (RCS) of the transponder tag. The need for flexible RFID tags has recently been increased enormously; particularly the RFID tags for the UHF band ensure the widest use but in the meantime face considerable challenges of cost, reliability and environmental friendliness.The multidimensional focus of the aforementioned research encompasses the production of low-cost and reliable RFID tags. The state-of-the-art fabrication methods and materials for proposed antennas are evaluated in order to surmount the hurdles for realization of flexible green electronics. Moreover, this work addresses the new rising issues interrelated to the field of economic and eco-friendly tags comprising of paper substrate. Paper substrates offer numerous advantages for manufacturing RFID tags, not only is paper extensively available, and inexpensive; it is lightweight, recyclable and can be rolled or folded into 3D configurations.The most important aspect of an RFID system's performance is the reading range. In this research several pivotal challenges for item-level tagging, are resolved by evolving novel structures of progressive meander line, quadrate bowtie and rounded corner bowtie antennas in order to maximize the reading distance with a prior selected microchip under the various constraints (such as limited antenna size, specific antenna impedance, radiation pattern requirements). This approach is rigorously evolved for the realization of innovative RFID tag antenna which has incorporated humidity sensor functionality along with calibration mechanism due to distinctiveness of its structural behavior which will be an optimal choice for future ubiquitous wireless sensor network (WSN) modules.The RFID market has grown in a two-dimensional trend, one side constitutes standalone RFID systems. On the other side, more ultramodern approach is paving its way, in which RFID needs to be integrated with broad operational array of distinct applications for performing different functions including sensors, navigation, broadcasting, and personal communication, to mention a few. Using different antennas to include all communication bands is a straightforward approach, but at the same time, it leads to increase cost, weight, more surface area for installation, and above all electromagnetic compatibility issues. The indicated predicament is solved by realization of proposed single wideband planar spirals and sinuous antennas which covers several bands from 0.8-3.0GHz. These antennas exhibit exceptional performance throughout the operational range of significance, thus paving the way for developing eco-friendly multi-module RF industrial solutions.

- An RFID antenna with integrated humidity sensor and calibration functionality for wireless sensor network is proposed. The antenna is composed of series and shunt stubs for impedance matching and reliability for near-field communication. The innovative ladder contour structure plays the key role for humidity sensing, and sensor calibration. The quadrangular end-tip loading is employed to offer capacitance and stability for far-field communication. The prototypes of the antenna are fabricated and tested: antenna effectively senses the ambient humidity levels while demonstrating stable behavior for RFID communication. The antenna has a compact size of 1 × 10cm for 902-928 MHz RFID band.

- Next generation wireless communications terminals will demand the use of advanced component integration processes and high density packaging technologies in order to reduce size and to increase performance. This paper presents highdensity multilayer interconnects and integrated passives used to design high performance prototype filter for 5GHz wireless LAN receiver realized on liquid crystal polymer (LCP) substrate. The thin film implementation of Multichip Module technology is identified as a useful platform for the integration of GaAs MMIC and silicon device technologies for microwave applications where performance, size and weight are critical factors. The ability of the MCM-D technology to provide controlled impedance, microstrip structures and integrated thin film passive components with useful performance in the microwave frequency regime has now been demonstrated.
