Six such groups of reflectors provide 96 bits of address space. Additional groups of overhead . In a delay line (DL) configuration, an ID code can be added in the time domain . In this paper, we propose a methodology for SAW tag design based on ANSYS .Six such groups of reflectors provide 96 bits of address space. Additional groups of overhead data are added for synchronization, error checking, and simultaneous detection of multiple tags (anti-collision). A key feature of SAW RFID tags is that they do not use any DC power source.
In a delay line (DL) configuration, an ID code can be added in the time domain signal, hence the name SAW-RFID or SAW-Tag. In this communication, we showcase recent original examples of SAW RFID sensors for harsh environment temperature and strain sensing, based on innovative electrodes and substrates. In this paper, we propose a methodology for SAW tag design based on ANSYS piezoelectric analysis simulation model. Using the methodology, two tags are simulated, designed, and fabricated. One has fixed number of electrodes in each reflector and varied electrode width.Design and operation of a typical SAW RFID tag. The principle benefit of this approach is that SAW RFID tags are capable of operating at much lower interrogator transmit power, and/or are capable of much greater range for a given transmit power than IC-based tags [Hartmann, et al.]. In this paper, we propose a methodology for SAW tag design based on ANSYS piezoelectric analysis simulation model. Using the methodology, two tags are simulated, designed, and fabricated.
The modulation method and overall tag data structure are reviewed for a family of proposed RFID devices. Current implementations use a basic group structure that encodes 16 information bits using 4 reflectors chosen from 75 reflector slots.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 . In this paper, we discuss the state-of-the-art in the development of SAW tags. The design approaches will be reviewed and optimal tag designs, as well as encoding methods, will be. In this paper, a novel SAW RFID tag based on UWB chirp spread spectrum theory was proposed. The tag designation is in accordance with FCC standards of UWB wireless communications.
The SAW RFID system consists of the SAW tag and the corresponding reader. The reader wirelessly interrogates the SAW tag and acquires its echo signal for identifying the tag coding [ 4 , 5 ]. The coding information of the SAW tag usually includes the time slots and the phase slots of all the coding reflectors on the tag [ 6 , 7 ].Six such groups of reflectors provide 96 bits of address space. Additional groups of overhead data are added for synchronization, error checking, and simultaneous detection of multiple tags (anti-collision).
