Radar Cross Section of Chipless RFID Tags and BER Performance [PDF]

open access: yesIEEE Transactions on Antennas and Propagation, 2020
The performance of different chipless RFID tag topologies is analyzed in terms of radar cross section (RCS) and bit error rate (BER). It is shown that the BER is mainly determined by the tag RCS once a standard reading scenario is considered and a fixed ...
