Abstract :
Radio frequency identification (RFID) deployment is needed for efficient item identification. A simulation environment in HP-ADS (advanced design system of agilent technologies) of Ultra High Frequency RFID systems is constructed in this paper. This paper simulates the system through an electrical model. The tag is represented by a simple empirical model representing the antenna by an amplifier and the chip. The chip is modeled by its impedance which varies with the code. A wireless channel with path loss and variable distance factors establishes the reader-tag link. The reader has a mono-static architecture. Performance of the whole system can be evaluated by changing the operating distance. Modeling improvement can be obtained by modifying the parameters of the building blocks. Finally, some simulation results are also included in this paper where data recovery is achieved.
