This research article proposes a novel, low-cost, dual-polarized
slot/resonator based structure. The tag has a triangular geometry and is
designed within a miniaturized footprint of 29 × 29 mm2. The proposed tag is capable of transmitting 38-bit data; which depicts that 238
number of different objects/items can be tagged. The tag is arranged in
such a manner that each slot i.e., (metal gap) corresponds to a
resonance dip or a logic state `1' in the radar cross-section (RCS)
curve. Similarly, a shorted/removed slot corresponds to a logic state
`0'. The tag has been realized for rigid as well as flexible substrates
which include, Rogers RT/duroid
®/5880, Rogers RT/duroid
®/5870 (flexible) and Taconic TLX-0 with copper as the radiating material. The frequency range for Rogers RT/duroid
®/5880 is 4.61-14.6 GHz, for Rogers RT/duroid
®/5870 (flexible) is 4.7-14.8 GHz and is 4.6-14.5 GHz for Taconic TLX-0
substrate. Hence, the compact, flexible and high data dense passive
chipless radio frequency identification (RFID) tag can be deployed in
various businesses and internet of things (IoT) based smart
applications.
