Abstract
This paper introduces the design and analyses of a new planar parallel microstrip quarter-circled multi-resonator (PQMR) for the chipless radio frequency identification (CRFID) that works in ultra-wide band (UWB) frequency region. The proposed PQMR has identifying (IDing) and potential sensing capabilities to work as a tag-sensor. The PQMR works within 3.30 GHz – 6.53 GHz with a high -10dB quality-factor (Q10dB) of 692, a good spatial density of as low as 7.05 mm2/bit, very good spectral density of 7.33 bits/GHz and a coding capacity of 17 bit with one-bit sensing ability. Different combinations of coding bit streams are also extracted to show the identification ability of the proposed design. This will motivate the CRFID designers to design small and high-capacity tag- sensors for UWB applications.
