Abstract
Chipless RFID is a potential alternative to chip based RFID for low cost applications. Enhancing the bit capacity and adding the programmable feature in a chipless tag has been approached via multiple techniques. We have taken advantage of the symmetry properties of split ring resonator to construct a mechanically reprogrammable chipless tag. A slotted signal line CPW (SSLCPW) is designed to produce high-Q resonances. Two port simulation results are presented and the tag is able to utilize 1 GHz bandwidth to generate atleast 225 IDs. A practical end to end implementation of the tag with two cross polarized UWB antennas is also proposed and results are presented for selected tag IDs.
