Abstract

Surface Acoustic Wave, SAW, Radio-Frequency Identification, RFID, tags have been fabricated on 128° Y-cut lithium niobate wafers. The RFID system consists basically of a set of tags and one or more reader units. Each tag is responsible for carrying a unique identification code. As it uses radio waves, it is not required to have an unobstructed line-of-sight view between reader and tag, unlike the optical approach. Besides, RFID may not require a human operator. Other advantages of the SAW RFID tags include: truly passive operation, multiple tags can be read by a single interrogation pulse, and possible combination of identification and sensor capabilities. In this paper, the design and fabrication of SAW RFID tags are presented. The characterization was performed in frequency and time domain.
