An RFID Enabled Miniaturized Chipless Tag for IoT Applications

In this research paper, a Novel, compact, low cost and entirely passive Chipless radio frequency identification tag are presented. The tag design comprises of 10 half cut cross loop-shaped resonant elements where each resonant element is represented by one encoding bit in the frequency domain. The tag has a compact geometrical footprint of 10.8×10.8mm

. The electromagnetic performance analysis of the tag is done by using multiple substrates Rogers RT/Duroid/5880, Rogers RT/Duroid/5870 and Taconic TLX-0. The Physical dimension of the proposed tag design is relatively small with very high bit capacity of 8.57 bits/cm

and spectral efficiency of 2.5 bits/GHz. The proposed tag design possesses the ability to generate 2

unique IDs for the identification process of various objects. The proposed tag operates in license-free UWB band having a frequency band of 3.5 GHz to 7.5 GHz. The proposed tag is appropriate to be deployed in the field of Internet of Things.
