“…In the preceding studies [19][20][21][22][23][24][25], a perfect alignment between the reader antenna and the tag is assumed when simulating and measuring the tag response. However, the practical situation is different, for the tag's azimuth and elevation angles are unknown to the reader antenna.…”

This paper focuses on the frequency coded chipless Radio Frequency Identification (RFID) wherein the tag’s information bits are physically encoded by the resonators’ notch position which has an effect on the frequency spectrum of the backscattered or retransmitted signal of the tag. In this regard, the notch analytical model is developed to consider the notch position and quality factor. Besides, the radar cross section (RCS) mathematical representation of the tag is introduced to consider the incident wave’s polarization and orientation angles. Hence, the influences of the incident wave’s orientation and polarization mismatches on the detection performance are quantified. After that, the tag measurement errors and limitations are comprehensively explained. Therefore, approaches to measureing RCS- and retransmission-based tags are introduced. Furthermore, the maximum reading range is theoretically calculated and practically verified considering the Federal Communications Commission (FCC) Ultra Wideband (UWB) regulations. In all simulations and experiments conducted, a mono-static configuration is considered, in which one antenna is utilized for transmission and reception.

Layout of (a) linearly polarized (LP) [3] (b) orientation insensitive (OI) [13] (c) cross-polarized (CP) [13] and (d) dual polarized (DP) tags [11] Recently, miniaturized versions of these tags are developed in millimeter (mm) wave frequency bands [14]- [15]. The tag size and reader antenna size are decreased in the mm-wave frequency band, which make it more suitable for commercial production than the tags which use the microwave frequency R band.…”

A 4×4 dual polarized (DP) aperture coupled microstrip patch antenna (ACMPA) array for a universal millimeter (mm) wave chipless RFID tag reader is presented. The mm-wave DP ACMPA array is capable of reading all types of frequency domain based chipless RFID tags (linearly polarized, orientation insensitive, cross-polarized and dual polarized) within its operating frequency bandwidth. The developed antenna is operating over the 22-26.5 GHz frequency band with 16 dBi realized gain and over 35 dB isolation. A systematic approach is followed for designing the mm-wave antenna array, where, firstly a single antenna element is designed. Then, a 1-32 way corporate feed network for the dual offset feeding of cross slots is designed using multistage power dividers. After that, the 4×4 mm-wave DP ACMPA array is designed, optimized, fabricated, assembled, and tested. Simulation and measurement results for different development stages of the array are described in detail. Finally, the assembled antenna is used for measuring ten orientation insensitive (OI) thermal printed mm-wave chipless RFID tags on a paper substrate to validate its functional accuracy. The developed mm-wave DP ACMPA array with high port-to-port isolation can be used in a universal commercial mm-wave chipless RFID tag reader due to its low cost, high gain and low profile structure.Index Terms-Antenna arrays, aperture coupled antennas, millimeter wave measurements, radio frequency identification (RFID), RFID tags.0018-926X (c) .

“…Chipless RFID as a contactless identification technique has gained acceptance due to its prosperous contribution in diverse commercial applications such as asset tracking, automated identification, item-level tagging, access management, and animal tracking on large scales [3]. The building blocks of a chipless RFID system are comprised of a reader, transponder, and data base for extracting and storing information from the remotely located tag [4,5]. In the literature, multiple approaches have been studied for designing chipless RFID tags achieving large information storing capacity and reliable performance.…”

A novel and miniaturized semi-elliptical 20-bit fully passive chipless RFID sensor tag is proposed in this article. The realized sensor tag is made up of semi-elliptical shaped open-end slots within the compact size of 25 mm × 17 mm. The multi-substrate analysis of the proposed tag is examined using non-flexible and flexible materials. The articulated tag configuration is capable of monitoring moisture levels when the largest resonator is covered by a heat-resistant sheet of Kapton HN (DuPontTM). The proposed tag functions in the operational frequency band of 4.1 GHz-16 GHz and possesses the overall bit density of 4.70 bit/cm 2 . The structure is composed of a thin passive substrate layer topped with an active layer of conductive path and is considered as a potential candidate for low-cost identification of the tagged objects. In addition to that, its moisture sensing property and flexible nature make it a reliable smart sensor for conformal applications.
