    Erroneous Reading of Information in Chipless Rfid Tags
    (Electromagnetics Academy, 2017) Boussada A.; Machac J.; Svanda M.; Havlicek J.; Polivka M.
    Chipless RFID tags are designed as arrays of planar or uniplanar resonators. These tags should be as small as possible to increase their attraction. On the other hand the closer are particular resonators located the tighter is their coupling. This coupling prevents the reader from proper reading the coded information. This is due to detuning of particular resonant frequencies of resonators and due to changing levels of the resonant peaks. Finally some compromise must be done in the tag design. For error-less reading of information coded by the presence/absence of resonant peaks in the RCS response the proper choice of scatterer topology and their arrangement has significant importance. Simple and efficient way of checking the suitability of particular resonators is presented. © 2018 Electromagnetics Academy. All rights reserved.
