Design and analysis of a truncated elliptical-shaped chipless RFID tag

This article presents a novel polarization-insensitive chipless radio frequency identification tag having an encoding capacity of 11 bits. The proposed resonator design comprises discontinuous arc slots forming truncated elliptically shape offering 1:1 slot to bit correspondence with suppressed unwanted harmonic resonances. Electromagnetic performance analysis the is done over ungrounded Rogers RT duroid® 5880 laminate. overall covers footprint 15 × 0.508 mm3 convincingly appreciable density 4.88 bits/cm2 . realized tags are analyzed for real-world electromagnetic resulting in agreement between measured and computed results. work finds its applications food beverage industry.
