A Model-Based Methodology for Real-Time Verification and Optimization of UHF RFID Systems

Nowadays, UHF RFID performance gains on increased importance as tags, readers, protocols and applications are addressed no longer as separated devices, but rather as a system. Resources of transponders are limited in size and available power, which is retrieved from the electric field generated by interrogator’s antenna. This power is restricted by national regulations. As UHF RFID systems have found their major application in highly inhomogeneous field environments of logistic processes, operating setups have critical influence on the performance of the system. This work proposes a methodology for optimization and real-time verification of UHF RFID systems. The novel method allows for considerations for operating setups in the design flow of components and brings a technique for verification of the system in application specific conditions. This technique is based on simulating models in real-time. The proposed methodology closes the gap between design of components and optimization of real-world setups in which the components operate.
