Abstract: Radiofrequency identification is an emerging and promising technology for the identification of individuals and goods: the automation of manual operation, rapidity, precise information... the are many RFID technologies. In this article, we are interested in the passive UHF RFID technology and especially to the calculation of parameters of spirals rectangular antennas for RFID. First we present a model based on the theory of diffraction by fine wires, we arrive at an integro-differential equation, this equation can be solved by using the method of moments. Although this method gives us a very good agreement with the measure, it remains gourmand in calculation time. We then develop a method to simplify the calculation of the parameters of spiral antenna for RFID tag without resorting to numerical analysis methods. In high frequency, when resonances appear, we introduce the propagation using the Transmission Line Theory. Knowing that this theory doesn't take into acco!
unt neither common mode currents nor lateral tracks of the loops. Then we introduce some improvements on it. These improvements consist on the one hand to integrate common mode in this theory decomposing excitations and on the other hand to correct the positions and magnitudes of resonances by introducing lateral tracks of these loops. The results obtained in this study highlight interesting prospects for future studies.
