“…The critical parameter that determines the performance of an RFID tag antenna is the reading range [7], which corresponds to the maximum distance at which the RFID reader can detect the modulated backscattered signal and successfully identify the tag. The reading range r can be obtained by means of the Friis free-space formula [2]:r=λ04πPr Gr Gtag τPc , where λ 0 is the free space wavelength, Pr = 1 W is the power transmitted by the reader, Gr = 4.5 dBi is the gain of the reader antenna, Gtag is the gain of the tag antenna, and τ is the power transmission coefficient defined in the previous subsection.…”

Low-cost and flexible radio frequency identification (RFID) tag for automatic identification, tracking, and monitoring of blood products is in great demand by the healthcare industry. A robust performance to meet security and traceability requirements in the different blood sample collection and analysis centers is also required. In this paper, a novel low-cost and flexible passive RFID tag is presented for blood sample collection tubes. The tag antenna is based on two compact symmetrical capacitive structures and works at the ultra-high frequency (UHF) European band (865 MHz–868 MHz). The tag antenna is designed considering the whole dielectric parameters such as the blood, substrate and tube. In this way, it operates efficiently in the presence of blood, which has high dielectric permittivity and loss. Measurement results of the proposed tag have confirmed simulation results. The measured performance of the tag shows good matching in the desired frequency band, leading to reading ranges up to 2.2 m, which is 4.4 times higher than typical commercial tags. The potential of this tag as a sensor to monitor the amount of blood contained in clinic tubes is also demonstrated. It is expected that the proposed tag can be useful and effective in future RFID systems to introduce security and traceability in different blood sample collection and analysis centers.

“…1. The framework of WPAMS consists of sub-1GHz radio frequency identification (RFID) [8,9] interrogator subsystem, antenna subsystem and passive RFID transponder subsystem. Compare to other interrogators, the sub-1GHz interrogator complies with ISO18000-6C and achieves larger communication range and suffers fewer reflections in the indoor space.…”

This paper presents the development of a brand new hardware framework of low-cost, tiny and power-efficient wireless monitoring system. The framework of this wireless personal area monitoring system (WPAMS) includes sub-1GHz RFID interrogator subsystem, antenna subsystem and passive RFID transponder subsystem. Compare to other interrogators, sub-1GHz interrogator achieves larger communication range and suffers fewer reflections in the indoor space. The sophisticated commercial transponder can be easily embedded in the personal belongings without any battery inside. In addition, a lightweight three-pass authentication process helps to form a simple point-to-point short-range identification network which makes our monitoring system is superior to other monitoring systems using active communication technologies, such as Bluetooth, ZigBee, UWB, Wi-Fi, and so on. Six experimental scenarios have been developed to demonstrate the performance on item-level identification. By connecting +5.7/5.5dBi right-hand circularly polarized commercial antennas and +1.7dBi linear polarized antenna, under 1 watt power limitation, the proposed WPAMS has successfully identified all the items within 2-meter range. The current PCB size of interrogator is 2-inch×3.25-inch×0.25-inch and can be reduced in the near future.
