CHIPLESS RFID TAG WITH AN IMPROVED MAGNITUDE AND ROBUSTNESS OF RCS RESPONSE

This paper describes properties of a new 20-bit chipless RFID tag of the size 52 x 50 mm(2), which exhibits an improved magnitude and robustness of the radar cross section. The tag is based on a novel slots-in-plate array approach, which is complementary to a typical tag consisting of an array of single resonators. In order to eliminate the detuning effect of the missing or shortening slots representing '0' bit information on the resonances of neighbouring slots signifying '1' bit information, the modification of the inter-element arrangement was proposed. Both ways of '0' bit information coding were studied and compared. (C) 2016 Wiley Periodicals, Inc.
