Tiivistelmä
In this letter, 8-bit paper based printable chipless tag is presented. The tag not only justifies the green electronic concept but also it is examined for sensing functionality. The compact tag structure comprises of seven L-shaped and one I-shaped dipole structure. These conducting tracks/dipole structures are of silver nano-particle based ink having a conductivity of 1.1 x 10(7) S/m. Each conducting track yields one bit corresponding to one peak. The tag design is optimized and analyzed for three different flexible substrates i.e. paper, Kapton (R) HN, and PET. The tag has ability to identify 2(8) = 256 objects, by using different binary combinations. The variation in length of particular conducting strip results in a shift of peak for that specific conducting track. This shift corresponds to logic state-1. The response of the tag for paper, Kapton (R) HN, and PET substrates is observed in the frequency band of 2.2-6.1 GHz, 2.4-6.3 GHz, and 2.5-6.5 GHz, respectively. The tag has an attractive nature because of its easy printability and usage of low-cost, flexible substrates. The tag can be deployed in various low-cost sensing applications.
