This paper presents an RFID passive system for the identification of moving vehicles within a monolane scenario. The system uses a HF-UHF RFID integrated transponder which consists of both a UHF meander dipole antenna and an ISO 15693 commercial tag arranged on a single ISO 7810 ID-1 Card. The UHF antenna is designed using a parametric analysis of the optimal shape of the meanders to obtain a proper conjugate matching between the antenna and the RFID microchip. A numerical analysis of a single-lane identification scenario is presented in order to asses the effects of the electromagnetic reflection and diffraction on the reading range as well as on the identification operations of a tagged vehicle. Numerical simulations and experimental results conduced on a transponder prototype confirm the possibility of using this technology for the identification of a moving vehicle approaching a nonstop road-toll system with a relatively slow speed.
