“…However, the authors have not presented any directivity/gain information in that particular work. So far, the smallest antenna (a rectangular patch) has been proposed in [9] with a dimension of 23 × 36 mm 2 and it has a maximum gain of 2.45 dBi for the retransmission-based CRFID tags. However, the gain to aperture (total area used by the antenna) ratio is still low at 0.23.…”

In this article, a new small size planar microstrip tree profile shaped Ultra-Wide Band (UWB) antenna with partial ground plane has been presented. The antenna is designed for chipless RFID tags that are working in UWB region. The operating frequency of the antenna is between 2.72 GHz to 11.1 GHz which covers the entire UWB frequency band. The antenna exhibits comparatively high realized gain of 4.2 dBi with respect to its small size of 27 × 40 mm 2 and have a gain to aperture ratio of 0.243 which is comparatively higher than other existing retransmission-based chipless RFID antennas. Another aspect of this antenna is its total efficiency which never goes below 80% throughout the entire bandwidth whereby it reaches as high as 96% at 3.5GHz. This design will motivate the chipless RFID designers to produce small size and cost effective tags.

“…The structure consists of 12 resonators and each two identical resonators have 37 states. Therefore, the 12 resonators provide 6 37 codes or equivalently approximately 31.3-bit. Significantly, the performance improvement is achieved by this configuration.…”

“…Moreover, the tag capacity can be increased by simply adding more resonators to the structure and the resultant mutual coupling can be reduced by adjusting the distance between the resonators [28]- [30]. Several chipless RFID tags have been developed based on two-state (1 bit) resonators [31]- [37]. The authors of [38], [39] presented spiral resonators to encode the data into a spectral signature.…”

“…Two orthogonal monopole antennas were then used to receive and retransmit the interrogatory signals with a small amount of mutual coupling between them. Other 1 bit resonators, such as open stub [31], open loop [33], L-shaped [36], and the complementary split ring resonator [37] have been investigated for chipless RFID applications. An improved structure was proposed in [40], [41] that combines a spiral and T-shaped coupled line in a compact form.…”

K-State Resonators for High-Coding-Capacity Chipless RFID Applications

This paper presents a new, compact, high-coding-capacity resonator suitable for applications in chipless RFID tags. These tags consist of multiple resonators and two cross-polarized ultra-wide band antennas. Each resonator contains a U-shaped coupled microstrip frame with isolated (K-1) legs inside. One of the legs is designed to be connected to the U-frame via a metallic strip in order to adjust its resonance frequency. Using this feature, the frequency of each resonator can be reconfigured to be equal to one of the K-resonance frequencies. Therefore, each resonance presents one of the Kstates of the resonator. This allows each resonator to represent more than one bit of information; this arrangement also permits N resonators tags to provide K N codes. The structure can store large volumes of data in a small area and can simplify the detection process by only reading N resonance frequencies for each code. When N resonator tags are used in the proposed structure, the amount of data that can be encoded increases to 2 (log K / log 2)N compared to 2 N in the case of conventional one-bit resonator (2-states) tags. An additional arrangement is also proposed and investigated in order to improve the spectral efficiency by allowing the bandwidth of each single resonator to be shared between two resonators. Several tags for codes with K = 8 are designed and implemented on the RT Duroid 5880 substrate as a proof-of-concept. An 8-state of the proposed resonator can be implemented in an area that is almost the same size as the area of a conventional 2-state resonator operating at 5 GHz. A satisfactory agreement between the empirical and simulated results is then confirmed.INDEX TERMS K-state resonator, high coding capacity, chipless RFID, ultra-wideband antenna (UWB), Internet of Things (IoT).

“…However, no gain and radiation pattern information has been revealed in that proposal. In the same way in [5], a rectangular UWB microstrip antenna has been proposed for a complementary split ring resonator (CSRR) based chipless RFID tag. The authors have used babinet's principle to design that antenna.…”

In this article, a microstrip-feed planar monopole ultra-wide band (UWB) antenna is proposed for the chipless RFID (CRFID) tag-reader systems with the intension to reduce the size of the tag. This antenna is keyhole shaped and small in size of 32 × 20 mm 2 compared with other existing antennas in the retransmission-based chipless CRFID system. The partial ground plane technique is applied here to obtain the bandwidth of 6.81 GHz within the UWB frequency spectrum. The results show it is suitable for both identification and sensing application in the retransmission-based CRFID. The antenna has a good omni-directional radiation pattern with realized gain up to 4 dBi and the realized gain to antenna size ratio goes as high 0.39/cm 2 which is comparatively higher than the other existing antennas in retransmission-based CRFID. The other feature of this antenna is it has the radiation efficiency up to 99% whereby it never goes below 96% throughout the working bandwidth and the measured antenna efficiency goes as high as 95%. Furthermore, to check the suitability to apply in CRFID sensor application, the proposed antenna has been realized on three flexible substrates of polyimide, PET and paper, and very little deviations are found compared to the rigid Rogers RT 3003 substrate in terms of S11, realized gain, efficiency and radiation pattern which is a proof of robustness of the design. This proposed antenna will motivate the researcher to develop a smaller sized UWB CRFID tags.
