Abstract
In a smart environment, accurate locations of objects are a fundamental and critical issue. To achieve this goal, we present several methods based on passive far-field UHF RFID technologies, which can satisfy accuracy, robustness and reliability, cost efficiency, simplicity, compatibility, and scalability. Passive UHF RFID system based localization is easily applied to the supply chains. In this research, we studied an effect of a passive UHF RFID reader antenna’s position to immobile object localization system in the monitoring area. When the localization system uses stationary RFID reader system, the performances of the system are significantly varied depending on the deployed antenna locations due to its external environmental influences such as RF reflection by the ground and obstacles. In this research, we deeply study the RF conditions and differentiation with various antenna location.
