Abstract

In order to design a robust passive temperature sensing tag that can operate over a wide temperature range, temperature-sensitive characteristic of UHF radio frequency identification temperature sensing chip and corresponding tags are studied. The devices under test include dipole tags with different antenna impedances. Simulation data, experiment design, system setup, measurement procedures, and test results are given. The results show that as temperature increases, the real part of chip impedance increases, and the absolute value of the imaginary part decreases, which are consistent with simulation data. In the full temperature range, the overall performance of sensing tags designed for high-temperature conditions is better than tags designed only for room temperature conditions.
