We present a numerical investigation of effective chipless tags for radio-frequency-identification (RFID) applications. Chipless tags have been introduced recently as alternatives to standard tags with microchips. While they can significantly reduce the overall cost of RFID systems by eliminating microchips and procedures to mount them on tags, chipless tags bring new challenges, especially in terms of identification reliability. We focus on tag structures that consist of resonators and consider alternative scenarios to find out potential misidentification cases. We also present the robustness of resonator-type elements in terms of fabrication errors, as well as array strategies to significantly increase electromagnetic responses of tags at the cost of reduced compactness.

Design, simulation, and fabrication of low-cost chipless rfid tags Çetin, Elif; Ergül, Özgür Salih; Department of Electrical and Electronics Engineering (2019) In this thesis, low-cost chipless radio-frequency-identification (RFID) tags are investigated. These types of tags are proposed and developed to replace barcodes in item-level tagging. In addition to the standard methods using printed circuit boards (PCBs), chipless RFID tags are suitable to be fabricated via low-cost inkjet printing. In these low-cost fabrications, tags are printed on photopapers via commercial inkjet printers loaded with silver-based inks. Various tag designs are simulated via the multile...
Improved Fonts for Chipless Radio-Frequency-Identification Tags Based on Letters Mutlu, Feza; Demir, Mehmet Alper; Ergül, Özgür Salih (2018-11-02) Using embedded microchips on radio-frequency identification (RFID) tags requires difficult mounting processes and increases the tag price. Therefore, chipless RFID tags have been introduced in the literature. In this paper, an improved series of chipless RFID letter-type tags are introduced. Each letter has unique characteristics that can be identified clearly, thanks to the well-designed slits opened to improve its electromagnetic response without sacrificing legibility. Simulations are realized for 150-po...
Design of Highly Distinguishable Letters for Inkjet-Printed Chipless RFID Tags DEMIR, MEHMET ALPER; MUTLU, FEZA; Ergül, Özgür Salih (2018-09-14) We consider chipless tags, which are based on Latin letters and also legible, for radio-frequency-identification (RFID) applications. Since letters using standard fonts have relatively weak and smooth responses with respect to frequency, special slits are designed to improve the distinguishability of letters without sacrificing their legibility. The designed set of letters can be used to generate words that are also suitable for RFID applications with their strong and unique scattering characteristics. The ...
Design of a radio frequency identification (rfid) antenna Kalaycı, Sefa; Birand, Mehmet Tuncay; Department of Electrical and Electronics Engineering (2009) Fundamental features of Radio Frequency Identification (RFID) systems used in different application areas will be reviewed. Techniques used in realizing RFID antenna systems will be studied and the procedure to realize a specific RFID antenna type possessing desired characteristics will be described. Electrical properties such as radiation pattern, impedance will be predicted using analytical and/or computer simulation techniques. Experimental investigations will be carried out to complement the theoretical...
Novel Inkjet-Printed Chipless Tags for Radio-Frequency-Identification Applications Cetin, Elif; Sailin, M. Baris; Ergül, Özgür Salih (2019-09-01) In radio-frequency-identification (RFID) systems, chipless tags, i.e., tags without microchips, are desirable in comparison to their more common counterparts involving microchips. This is not merely due to the extra costs of microchips but also due to relatively difficult mounting processes to attach microchips onto metallic antennas, which in fact becomes challenging if tags are produced via inkjet printing methods. In the context of paper-based inkjet printing, absence of microchips is also attractive for...
