“…The fundamental RFID system is made out of tag [8] from which we can remotely retrieve data, reader [9], and database where we stock identified object information. The physical connection between the reader and the tag is wireless and dependent on the electromagnetic coupling between their antennas.…”

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.

This article proposes a new and simple miniaturized tag for radio frequency identification (RFID) in the European and Moroccan UHF band (866-868 MHz). This tag can be mounted on the surfaces of the human body and may be used for identification cards. For human body modelling, we used a four-layer laminated elliptical cylinder with physical parameters for electromagnetic simulations. The radiation characteristics of the antenna placed in proximity to the human model and the effects of absorption caused by the human body were analysed and controlled. Our antenna is composed of a meander dipole and a T-shaped adaptation network structure. We used the CST-MS for the design of the antenna and the human body model and verified the results with the HFSS simulator. The designed tag was manufactured to test the reading range. The measured range is about 6 m when the tag is placed near to the chest and between hands. The new features of the proposed new tag are characterized by its simple structure, reliable stability on the surface of the human body, a long reading range and a miniaturized size of 46 x 20 mm 2. Our antenna was designed on a low-cost, single-sided FR-4 substrate with a thickness of 0.8 mm. Compared to the conventional ultra-high frequency patch; our antenna achieves a miniaturization rate of 91%.
