“…Numerous techniques are proposed for the impedance matching such as T-match network [12], double T-matching structure [13] and inductively coupled loop [14]. Other techniques are used to reduce the antenna's dimensions including meandering [15], which increase the electrical length of the tag antenna, fractal, inverted-F antenna (PIFA), Split Ring Resonators (SRR) structures, and slot's technique which consists of cutting slots of different shapes from a patch antenna [16][17][18].…”

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.

“…For handy applications, RFID tag antennas must be compact, suitable for low-cost and reasonable for ease large scale manufacturing [13] and must also have specific antenna impedance. Many papers presented in the literature provided different techniques for reducing the size of the antenna, such as meandering, fractal, inverted-F, or Split Ring Resonators (SRR) structures [14][15][16][17], and other for the impedance matching, such as T-match network [18], double T-matching structure [19] and inductively coupled loop [20].…”

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.
