Abstract—In this letter, a printable chipless tag with electromagnetic
code using split ring resonators is proposed.
A 4 b chipless tag
that can be applied to paper/plastic-based items such as ID cards,
tickets, banknotes and security documents is designed. The chipless
tag generates distinct electromagnetic characteristics by various
combinations of a split ring resonator. Furthermore, a reader
system is proposed to digitize electromagnetic characteristics and
convert chipless tag to electromagnetic code.
Index Terms—Chipless tag, electromagnetic code, split ring resonator.
