“…Several approaches are suggested in the scientific literature for impedance adaptation and miniaturization of the RFID tag antenna. The proposed feeding methods for adapting the antenna tag with the chip are T-match network, inductively coupled proximity loops, and the inclusion of nested or shaped slots [9][10][11]. For size reduction without significant trade-offs of tag performance, meander line structure by folding the arms of a dipole is utilized to increase the electrical length of the tag antenna [12][13][14][15], an inverted planar F antenna with a short-circuit pin used to reduce the size of a vertical wire monopole, and patch antenna with different shapes using slots on the design [16][17][18][19].…”

This article suggests a simple and new miniaturized antenna for radio-frequency identification (RFID) tags in the European and Moroccan UHF band (866-869 MHz). Our structure consists of a meandering dipole, L-shaped radiators and a changed T-Match network. The meander technique was applied to decrease the antenna size; using this method, the size of our structure has been reduced to 68% compared to the classical UHF dipole. L-shaped radiators and a modified T-matching approach are also used to easily match the antenna input impedance to that of the chip to maximize power transfer. The size of our antenna is 50 x 22 mm 2 , it has been designed on a single-sided FR-4 substrate with a thickness of 0.8 mm for a relative permittivity, Ɛr of 4.4. For our design, we chose the Higgs 4 IC chip (manufactured by Alien Technology, USA) which has an impedance of 20.5-j191 Ω obtained at the centre frequency 867 MHz. The antenna performance was studied with respect to the impedance matching, realized gain, reflection coefficients and read range of the label. Therefore, the proposed design achieved a gain of 1.2 dB and a maximum reading range of 13.94 meters at 867 MHz.

“…Further, some tag antennas using slots on patch [12–14] and miniaturized antenna design using patch [15] have been discussed. Other tag antennas using meandered dipole with T-matched and inductive coupled feeding techniques [11, 16–23] have been reported for effective conjugate matching of input impedance. Double and triple split ring antenna topologies have also been reported to reduce the electric length of tag antenna [24], which further reduces the effective size of the antenna.…”

“…To increase the electrical length of the tag antenna, the meander line structure is utilized and method for calculating resonance frequency is detailed in literature [26]. Out of the various techniques used for size reduction, dipole-based meandering size reduction and inductive coupled feeding techniques are reported to result better performances [11, 16–23].…”

The development of compact radio frequency identification (RFID) tag is the key requirement for wireless tracking of precious small size goods/packages in transport. A design of compact meander line tag antenna having inductive coupling feed is presented for RFID system operating at ultra high frequency band of865–867 MHz. The size of the proposed tag antenna is43 mm × 10 mm, and is designed using Higgs 4 IC chip (made Alien Technology, USA) having impedance of20.55− j191.45 Ωat centre frequency866 MHz.The antenna characteristics such as impedance, radiation pattern, bandwidth, and effect of ground on gain and tag size are analyzed and found to closely match with the simulated values. The observed value of reading range varies from87.5 to 35 cmsdepending on mounting on non-metal and metal packages, respectively.
