“…RFID technologies require antennas with small sizes and high performances such as a large bandwidth, a multi-band operation [3]- [10] and, a high gain [11], [12]. There exists various techniques to realize multi-band antenna, for example, metamaterial technology [6], [14], [15], multilayer substrates [14], fractal technology [6], [16], slot reactive loading [4], and [17]- [20]. A slot loading can not only realize antenna multi band, but also realize broadband and miniaturization.…”

“…A slot loading can not only realize antenna multi band, but also realize broadband and miniaturization. A number of antennas have been proposed previously [4], [13], [16]- [33]. However, many of them they are not compact and sometimes a physical realisation of the antenna is difficult in reality.…”

This paper presents a new design of dual band RFID reader antenna for ISM-band industrial science and medical applications at 2.4 GHz and 5.8 GHz. Theantenna is designed and physically built using FR4 substrate and taking a 1.5 thickness, 4.3 relative permittivity and 0.025 loss tangents. Different slots havebeen introduced to reduce the antenna dimensions and to achieve the dual bandfor microwave ISM band application. The dimension of the proposed antenna is 34 × 34 × 1.5 mm3, which it could be easily integrated into RFID readers.Numerical simulations have been performed usingcomputer simulationtechnology (CST) Microwave Studio software. A parametric study wasinvestigated in order to show the effect of slots variation and to obtain the desiredfunctional characteristics. Experimental results show a good agreement withresults obtained by simulations. A satisfactorily omnidirectional for the radiationpatterns across the antenna operation bands was obtained.

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.

“…There are four diverse frequency bands apportioned for RFID applications, low frequency (LF: 125-134 kHz), high frequency (HF: 13.56MHz), ultra-high frequency (UHF: 860-960 MHz) [10] and microwave frequency (2.45GHz and 5.8GHz) [11]. Different nations have allocated different frequency bands for UHF-RFID applications; e.g., China (840-845 MHz), Europe (866-869 MHz), USA (902-928 MHz) and Australia (920-926 MHz).…”

In this work, a novel passive tag antenna has been designed, investigated and proposed for UHF RFID applications. It has a small size and can operate in the North and South American band (902-928 MHz). The proposed antenna was etched on a low-cost FR4 substrate with an overall size of 54 × 24 × 0.8 mm 3 in order to be applied as UHF RFID tag antenna at the center frequency of 915 MHz. It consists of embedded Π-match, meandered arms, and an RFID chip placed at the center. The meander line technique is used to assure the miniaturization and the Π-match technique to have a good impedance matching. This antenna has a good reflection coefficient and good read range.
