Abstract: This paper describes the environmental effects and performance analysis of 2.45 GHz Surface Acoustic Wave (SAW) based RFID systems. Piezoelectric materials and their underlying principles are reviewed to describe the nature of SAWs. A performance analysis is conducted to measure the readability and read range for individual tags, compared to multiple tags in a field environment. On the other hand, effects of temperature, humidity, altitude and vibration on the readability and operability of the system are described. Finally, a conclusion is drawn with regards to the performance of SAW-based RFID systems.
