“…According to Figure 4 , an eligible coding capacity of 60 bits can be then obtained, leading to theoretical spatial coding density of about 300 bits/cm 2 . Such a performance is several orders of magnitude better than coding density obtained with a chipless RFID system [ 4 , 5 , 6 , 7 , 8 ], mainly since THz wavelengths are a hundred times smaller than in the RF .…”

“…Chipless RFID is mainly based on resonator technology and the tag’s performance of course depends on the resonators design, number, the selected frequency range, and on the coding technique. Moreover, in the RF domain mainly, the design of chipless structures, and more generally the research for efficient performance, remains a hot topic subject with very rapid development [ 4 , 5 , 6 , 7 , 8 ]. The best performances published in the last two years reach about 30 bits but remains for the majority around 20 bits, corresponding to spatial density in the range of 1 bit/cm 2 , very exceptionally around 10 bits/cm 2 or higher.…”

In this article, we report on video-rate identification of very low-cost tags in the terahertz (THz) domain. Contrary to barcodes, Radio Frequency Identification (RFID) tags, or even chipless RFID tags, operate in the Ultra-Wide Band (UWB). These THz labels are not based on a planar surface pattern but are instead embedded, thus hidden, in the volume of the product to identify. The tag is entirely made of dielectric materials and is based on a 1D photonic bandgap structure, made of a quasi-periodic stack of two different polyethylene-based materials presenting different refractive indices. The thickness of each layer is of the order of the THz wavelength, leading to an overall tag thickness in the millimetre range. More particularly, we show in this article that the binary information coded within these tags can be rapidly and reliably identified using a commercial terahertz Time Domain Spectroscopy (THz-TDS) system as a reader. More precisely, a bit error rate smaller than 1% is experimentally reached for a reading duration as short as a few tens of milliseconds on an 8 bits (~40 bits/cm2) THID tag. The performance limits of such a tag structure are explored in terms of both dielectric material properties (losses) and angular acceptance. Finally, realistic coding capacities of about 60 bits (~300 bits/cm2) can be envisaged with such tags.

“…Co-polar tags can further be delineated as either linearlypolarized or orientation insensitive tags, where linearly-polarized tags require precise polarization alignment between the tag and the reader antenna, while orientation insensitive tags do not [20,27,40,45,[69][70][71][72][73][74]. There are also dual-polarized tags that are a special case of co-polar tags; they are designed to be read in two orthogonal polarizations that are co-polar with the polarization of the reader antenna.…”

“…There are also dual-polarized tags that are a special case of co-polar tags; they are designed to be read in two orthogonal polarizations that are co-polar with the polarization of the reader antenna. In the case of dual-polarized tags, the reader antenna is typically either dual-polarized, or the orientation of the reader antenna relative to the tag is changed to measure the tag in the two polarizations [69,72,[75][76][77][78].

Chipless RFID systems can be considered as a special case of passive RFID systems, where the tag contains no power source and no electronics. Instead, the tag's information is stored in its structure and accessed through its electromagnetic (EM) scattering response. However, robust response detection, which is primarily a function of the measurement method, measurement equipment, and processing method used, is still a major challenge in the chipless RFID field. The consequences of not properly capturing a tag response include, incorrectly assigning an ID or incorrectly reporting a sensing parameter. Due to the criticality of these challenges, this review seeks to provide an overview of the current measurement methods, equipment architectures, and processing methods as they relate to chipless RFID tag response detection and decoding. Since chipless RFID started gaining popularity around 2005, the developments in this area have been focused on three major categories: timedomain, frequency-domain, and spatial-domain systems. Frequency-domain systems have emerged as the most popular among these three categories, and thus, this review focuses on techniques used for these systems.

“…Bazı mikrodalga aktif etiketler, karşılaştırılabilir UHF etiketlerinden daha az olan 30 metreye kadar olan aralıklardan okunabilir. Bununla birlikte, mikrodalga RFID etiketlerinin fiziksel uygulamaları, daha düşük frekanslı RFID etiketlerinden çok daha küçük ve kompakt olabilir [22].  RFID'ye uygulanan ultra geniş bant (UWB) teknolojisi oldukça yenidir.…”

Bu çalışmada, envanter yönetimi amacıyla düşük maliyetli ve esnek kullanıma uygun ultra yüksek frekanslı (UHF), radyo frekansı ile tanımlama (RFID) sistemi gerçekleştirilmiştir. Oluşturulan sistem ile envanterde bulunan ürünlerin güvenliği ve izinleri tek bir noktadan etkin bir şekilde sağlanmıştır. UHF RFID sistemine ait iki adet uygulama noktası oluşturulmuştur. Bunlardan birincisi, kullanıcı izinlerinin sağlandığı merkez nokta ve diğeri ise giriş ve çıkışların denetlendiği güvenlik noktasıdır. RFID etiketlerinden elde edilen bilgilerin tek bir noktadan değerlendirilmesi hedeflenmiştir. Operatör ile uzun mesafeli UHF RFID okuyucu arasındaki iletişim RS485 seri iletişim veri yolu standardı ile sağlanmıştır. Güvenlik noktasından, UHF RFID anten yardımı ile okunan bilgilerin anlamlı hale gelebilmesi ve kararlılığın artırılması amacıyla etkin veri işleme yapısı kullanılmıştır. UHF RFID envanter yönetim sistemine ait esnek bir grafik kullanıcı arayüzü (GUI) oluşturulmuştur. Kütüphane envanter yönetimi için özelleştirilen sistemin başarımı gerçek kullanım senaryoları üzerinden test edilmiştir.
