Abstract :
This paper investigates practical, wideband considerations that affect the performance of modulated passive UHF RFID tags. The tag-antenna´s structural scattering term can be favorably exploited increasing the total backscattered power, by properly selecting the circuit´s parameters within realistic values, as shown herein. Frequency domain analysis of the simplified circuit is carried out in the operational UHF frequency band. Small performance-degradation, with respect to power at the rectifier and mean backscattered power, is recorded away from resonance. However, Bit Error Rate is shown to vary greatly within the frequency band.
