“…Split-ring resonators are employed in a broad field of applications (Schueler et al, 2012). There are systems described in literature, e.g., for dielectric characterization of liquids (Ebrahimi et al, 2014) or analysis of organic tissues (Puentes et al, 2011). Furthermore, they are found useful for measuring physical values like distance and rotation (Naqui et al, 2011).…”

Abstract. Split-ring resonators are electrical circuits, which enable highly sensitive readout of split capacity changes via a measurement of the shift in the resonance frequency. Thus, functionalization of the split allows the development of biosensors, where selective molecular binding causes a change in permittivity and therefore a change in split capacity. In this work, we present a novel approach using transmission line theory to describe the dependency between permittivity of the sample and resonance frequency. This theory allows the identification of all relevant parameters of a split-ring resonator and thus a target-oriented optimization process. Hereby all setup optimizations are verified with measurements. Subsequently, the split of a resonator is functionalized with aptamers and the sensor response is investigated. This preliminary experiment shows that introducing the target protein results in a shift in the resonance frequency caused by a permittivity change due to aptamer-mediated protein binding, which allows selective detection of the target protein.

“…Transmission lines loaded with split ring resonators (SRRs) and with other electrically small resonators [1][2][3][4][5] have been used in numerous microwave applications, including filters [6,7], enhanced bandwidth components [8], multiband components [9][10][11][12], microwave sensors [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] and chipless radiofrequency identification (chipless-RFID) tags [31,32], among others. Concerning chipless RFID tags, the interest in this work, transmission lines loaded with multiple resonant elements, each tuned to a different frequency, have been proposed as multi-resonant frequency domain based tags [31][32][33][34][35][36][37][38][39][40][41][42][43][44].…”

High data density and capacity in chipless radiofrequency identification (chipless-RFID) tags based on double-chains of S-shaped split ring resonators (S-SRRs)

et al. 2017

Abstract. The data density per surface (DPS) is a figure of merit in chipless radiofrequency identification (chipless-RFID) tags. In this paper, it is demonstrated that chipless-RFID tags with high DPS can be implemented by using double-chains of S-shaped split ring resonators (S-SRRs). Tag reading is achieved by near-field coupling between the tag and the reader, a CPW transmission line fed by a harmonic signal tuned to the resonance frequency of the S-SRRs. By transversally displacing the tag over the CPW, the transmission coefficient of the line is modulated by tag motion. This effectively modulates the amplitude of the injected (carrier) signal at the output port of the line, and the identification (ID) code, determined by the presence or absence of S-SRRs at predefined and equidistant positions in the chains, is contained in the envelope function. The DPS is determined by S-SRR dimensions and by the distance between S-SRRs in the chains. However, by using two chains of S-SRRs, the number of bits per unit length that can be accommodated is very high. This chipless-RFID system is of special interest in applications where the reading distance can be sacrificed in favor of data capacity (e.g., security and authentication). Encoding of corporate documents, ballots, exams, etc., by directly printing the proposed tags on the item product to prevent counterfeiting is envisaged.

“…Compact wideband and ultra-wideband (UWB) filters [10], power dividers [11] and microwave sensors [12]- [13] among other devices, have been implemented by means of SRR-or CSRR-loaded lines. The control of the phase constant and characteristic impedance (a unique feature of metamaterial transmission lines) in SRR-and CSRR-loaded lines has also been successfully applied to the design of leaky-wave antennas with broadside and backward-to-forward radiation capabilities [14]- [16].…”

Abstract-The radiation properties of split ring resonators (SRRs) at their second resonance frequency are studied for the first time in this work. In particular, the electric and magnetic dipole moments of the edge-coupled SRR (EC-SRR) are calculated analytically under the assumption of strong coupling between the internal and external rings. Based on these results, the radiation resistance and the radiation efficiency are obtained theoretically. Electromagnetic simulations of the structure reveal that there is very good agreement with the theoretical predictions, pointing out the validity of the proposed analysis. As a proof of concept, an SRR antenna prototype is designed and fabricated. Experimental data are in good agreement with the theoretical and simulated results, and demonstrate the validity of the SRR working at its second resonance frequency as a radiating element.Index Terms-Split ring resonators (SRRs), planar antennas, radiation efficiency, metamaterials.
