“…The simulation data show that as the temperature rises, R p decreases and C p rises, that is, the real part of the chip impedance increases and the absolute value of the imaginary part decreases. This trend is also consistent with the relationship between the real part of the impedance and the temperature of another UHF RFID chip measured in [5]. But in [5], the imaginary part of the chip impedance is nearly unchanged with temperature because the chip has an automatic tuning function and can adjust C p within a certain range.…”

“…This trend is also consistent with the relationship between the real part of the impedance and the temperature of another UHF RFID chip measured in [5]. But in [5], the imaginary part of the chip impedance is nearly unchanged with temperature because the chip has an automatic tuning function and can adjust C p within a certain range. The chip used in this paper doesn't have this function so we can see the variation of the C p with the temperature in Table 1.…”

“…The relative permittivity of antenna substrate material is about 4.4 at room temperature. It should be noted that the dielectric constant of the antenna substrate varies with temperature, and the metal material forming the antenna itself, and the antenna substrate material also has corresponding thermal expansion coefficients, which affect the antenna impedance value [5]. However, it can be considered stable with temperature in our tests due to its thickness, and even if it changes, the change is also the same proportion for both antennas.…”

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.

“…However, the UHF tags are more sensitive toward its tagging surfaces and environments, which is considered to be a major drawback inherited with UHF tags. Conversely, this sensitivity toward tagged surfaces makes UHF tags a battery‐less and low‐cost sensing device, which is pivotal for IoT applications . As with the advancement of technologies people are becoming health conscious.…”

This article presents an RFID system to detect the salinity and sugar contents of water. The proposed system is based on low‐cost ink‐jet printed passive ultrahigh frequency (UHF) RFID tag. The tag is designed using slot match technique, which poses a good imaginary impedance match with RFID chip both in free space and after mounting on the water bottle. Moreover, the tag antenna is exploited as a sensor to detect salt and sugar contents of water by measuring the backscatter power from the tag in term of received signal strength indicator (RSSI). A Tagformance Pro setup form Voyantic is used for measuring RSSI. Furthermore, an approximate relationship is derived between backscatter power and no. of grams of salt and sugar dissolved in water. This study paves a way to check the contents of drinks using portable devices, which is pivotal for healthcare applications in smart cities and the future Internet of things (IoT).
