“…The RFID system with allocated low frequency (125-134 kHz), high frequency (13.56 MHz), ultrahigh frequency (UHF) (860-960 MHz), and microwave frequency (2.45, 5.8, and 24 GHz) [5] has pulled attention for its variety of applications as of late. UHF-band RFID systems particularly provide long-range, faster reading and greater information storage capacity [6] than those operated in the lowand high-frequency (LF or HF) bands.…”

A miniaturized tag antenna is presented in this paper, for operating in the RFID UHF American band, in free space or in a metallic environment. The proposed antenna is printed on a single layer FR4 substrate, and designed first to work in a free space. The shape of the π-match allowed us to achieve a good matching between the antenna impedance and that of the chip. The correspondence between simulation results in CST and HFSS pushed us to manufacture a prototype of our tag. After that, we simulated the proposed antenna in a metallic area, by adding a square metal plate separated with the antenna by a foam-layer, in order to test the performance of the tag in this environment. An optimization procedure enabled us to achieve a good performance when operating in metallic surroundings. Finally, we tested the reading range of the manufactured tag. We obtained a good range of about 6.5m. The final design of our proposed tag has a simple structure, a dimension of 51×26,63×0.8 3 and which is reduced by 88,64% compared to the calculated theoretical dimensions of a patch antenna operating at the resonant frequency of 915 MH.

“…They are energized by the reader's signal. In a passive RFID tag, the input impedance of the antenna is matched with the conjugate impedance of the tag IC for maximum power transfer from the antenna to chip [11]. Passive RFID microchips have capacitive impedances.…”

“…The RFID tag antennas are usually low profile and small as the overall dimension of the tag depends on the size of the antenna. The 4 main frequency bands allocated for RFID systems are: low frequency (125‐134 kHz), high frequency (13.56 MHz), ultrahigh frequency (UHF) (860‐960 MHz), and microwave frequency (2.45, 5.8, and 24 GHz) . The UHF systems are preferred as they allow detection of more number of tags simultaneously, offer longer read ranges and higher reading speeds and also require smaller antennas compared to low frequency and high frequency systems .…”

A miniaturized UHF dual‐band passive RFID tag antenna operating in the 866‐869 and 950‐956 MHz bands is proposed. It consists of an S‐shaped Folded Dipole Antenna (FDA) resonating at 912 MHz, which is intermediary between the two required frequencies. To obtain dual‐band response perturbation method is employed. The electrical length of the FDA changes on loading a 2‐turn spiral resonator (2‐SR) to it. The 2‐SR splits the tag resonance at 912 MHz into two resonance frequencies (867 and 956 MHz). The proposed design is simulated using HFSS and then fabricated. Measured reflection coefficients at 867 and 956 MHz are −13.25 and −13.34 dB, respectively, exhibiting a 10 dB bandwidth of 11 MHz from 859 to 869 MHz and a 5 MHz 10 dB bandwidth from 953 to 957 MHz. Maximum read ranges of 5 m in 866‐869 MHz and 3.3 m in 950‐956 MHz band have been measured.

“…Generally four frequency bands are used for RFID systems; i.e., low frequency (125-134 kHz), high frequency (13.56 MHz), ultra-high frequency (860-960 MHz) and microwave frequency (2.45, 5.8 and 24 GHz) [2]. The ultra high frequency (UHF) tags have garnered more attention as they offer longer read ranges, higher reading speeds, enable simultaneous detection of more number of tags and need smaller antennas than low frequency (LF) and high frequency (HF) systems [3].…”

Abstract-A low profile dual-band passive Ultra High Frequency Radio Frequency Identification (UHF RFID) tag antenna designed to operate at two RFID bands allocated for use in and Japan (950-956 MHz) is proposed. The antenna has two eccentric circular rings of different radii to provide dual band response. An arc-shaped strip with Impinj Monza-4 IC chip is used to feed the two rings simultaneously by microstrip-line coupling-feed technique. The proposed design is simulated using Ansoft HFSS, and the prototype is fabricated. The return losses at 866 MHz and 952 MHz are measured to be −12.25 dB and −12.99 dB, respectively, which are in good agreement with the simulated results. The proposed antenna exhibits a 10 dB bandwidth of 9 MHz from 862 to 870 MHz and an 8 MHz 10 dB bandwidth from 949 to 956 MHz covering the UHF RFID bands in Europe and Japan. The maximum read ranges are measured to be around 3 m in the 865-868 MHz band and 2.6 m in the 950-956 MHz band.
