“…Recently, metamaterial-inspired resonators have also been used to shrink tag dimensions [6], due to their very small dimensions in terms of wavelength. Among these, the edge coupled split ring resonator (EC-SRR), first proposed by Pendry [7], has been also reported as a standalone radiating particle for UHF-RFID tags [8], [9]. However, in [8] the authors declare that the radiating part is only the external ring, being the internal ring much smaller and dedicated to the impedance matching functionality between the ASIC and the antenna.…”

Abstract-An electrically small planar passive UHF-RFID tag based on an edge-coupled split ring resonator (EC-SRR) antenna is presented in this work. In order to explore the potentiality and limitations of the SRR antenna and to aid the tag design, an analytical study of the SRR radiation properties at its fundamental resonance is presented for the first time. Radiation resistance, efficiency, polarization, bandwidth and impedance matching with the RFID ASIC are treated in the study. Based on such analysis, the tag design process is presented, and a tag prototype of size 30 mm × 30 mm (λ 0 /11 × λ 0 /11) is designed to operate in the North-American UHF-RFID band (902−928 MHz) and manufactured. The measured read range is in good agreement with the simulation, and reaches 9.3 m at 911 MHz. The tag also features a mitigation of the blind spots, providing a minimum measured read range of 4.2 m.Index Terms -Split ring resonators (SRRs), electrically small antennas (ESAs), radio frequency identification (RFID).

“…So, to obtain a good impedance matching, the input antenna impedance must be the same as that of the input impedance of the chip, that is, R a ≈ R c at a working frequency. To resolve this problem, a split ring resonator (SRR), which was first proposed by Pendry, is used as a radiating part and an inductively coupled feeding method in order to obtain a long‐read range and more compact antenna size . The studies on this type of antenna have progressed very quickly.…”

In this article, a new design of miniaturized split-ring resonator antenna using a meander line technique with a simple impedance matching method applicable to UHF-RFID tags is presented. The new approach is based on the integration of a meander line into the radiating element of SRR to reduce the electrical tag size and a theoretical demonstration to calculate the conjugate impedance matching and directly attach the antenna with the chip. The new SRR antenna, which is printed on the flexible substrate Arlon CuClad 250LX, is designed using Alien Higgs 3 RFID ASIC whose input impedance is 25-j190. The prototype antenna has a low-cost compact size (18.28 mm × 18.28 mm) with a read range higher than 4 m within the RFID UHF band and with a roughly 4.2-m peak range at 915 MHz. As a proof of behavior, a tag prototype is fabricated and measured to operate at a UHF RFID band. Based on some works' results, an optimized design is obtained with a 48% size reduction compared with the classic split ring resonator antenna and with a good impedance matching the antenna with RFID ASIC without the need for any external matching network. K E Y W O R D S compact antenna, passive tag antenna, split ring resonator, UHF RFID application 1 | INTRODUCTIONNowadays, radio frequency identification (RFID) is becoming an increasingly interesting technology for research due to its high data rate, easy read/write functions and long readable range between the reader and tag. This development in RFID technology has led to great demands in different fields all over the world, such as smart parking application agriculture, airport access control, libraries, vehicle security military, passport, supply chain, and mobile payment. 1,2 In the applications of RFID systems, the only active component reader sends radio frequency signals and information to a passive tag which includes an antenna and an integrated circuit (ASIC). The chip which contains the information about the tagged item converts the unmodulated signal and sends its information back to the reader for the automatic identification of objects. 3,4 In several UHF RFID applications, we need a small-tag antenna to be flexibly mounted on different device components. For this reason, the major challenging aspect concerning passive UHF RFID tags is the size reduction. In literature, there are lots of studies which have been reported on small tags based on dipole or patch antennas. In Ref. 5, the authors presented an overview of the RFID passive tag in terms of antenna impedance, chip impedance, antenna performance, and read range measurement. Moreover, a study on the performance of RFID U-shaped dipole tag antenna that is placed on different permittivity surfaces has been reported in Ref. 6. For near-field applications, 7 a meander line tag antenna designed for Europe band and used for short-distance RFID UHF tagging for tracking packages in transport is proposed. In Ref. 8, an RFID tag dipole antenna operating at the whole UHF frequency band has been presented to be used for bandwidth optimizati...

“…However, it is still faced with a difficulty in impedance matching because the small loop has small radiation resistance and large reactance [5,13]. For solving this problem, printed split-ring antennas (SRAs) consisting of a small inner fed ring and an outer coupled split ring element are presented to match the impedance [14][15][16]. However, these antennas have neither a ground plane nor a backing conductor.…”

This paper presents a low-profile and compact printed antenna having an omnidirectional radiation pattern with horizontal polarization to the ground. The proposed antenna consists of an inner small fed ring, an outer coupled split ring, and a ground plane. The overall dimension of the proposed antenna is 45 mm × 50.5 mm × 11.6 mm (0.138 0 × 0.155 0 × 0.036 0 ). The −10-dB | 11 | of the antenna covers the 920-MHz RFID band, and the gain is about 1.45 dBi in the parallel direction to the ground plane. The measured results show good agreements with the simulated results. Furthermore, the reasons for the low-profile structure and the omnidirectional radiation pattern are also discussed.
