“…The RFID chip used in this design is Murata (LXMS31ACNA) chip [17], with an equivalent resistance of 17.6 Ω and a capacitance of 1.62 pF in series at 915 MHz, and has a minimum power activation of -8 dBm. The RFID chip used in this work exhibits a high capacitive measured reactance Z chip = 17.2-j100.9 Ω [18], which can be cancelled by adding rectangular patch at each corner of the loop. This technique provides an easy input impedance matching.…”

In this paper, we report a new design of a multifunction RFID tag antenna operating in the European band (665-868.5MHz) and the North American band (902-928 MHz) separately. The multifunction behavior can be achieved by changing the position of the RFID chip. It is found that at each feeding position, the RFID tag antenna can operate separately on both bands. The characteristics of the proposed design including S-parameters, impedance and reading range pattern have been investigated using simulation software CST Microwave Studio and experimental results. Further insight into the mechanism radiation is sought through the investigation of the current density and the equivalent circuit model. The tolerance of this design on various background materials is also investigated experimentally. The measured and simulated results show good agreement, providing a simple and low-cost design.

This paper presents an evaluation on double loop integrated circuit module for inductive couple fed RFID Tag. The inductive couple feed gives advantage especially for flexible wire embedded antenna in controlling the manufacturing varians as the chip is not directly connected to the antenna. Thus electrostatic discharged effect and manufacturing errors can be minimized. An inductor loop is directly connected to the RFID chip before it is placed to indirectly coupled the energy from a meandered dipole antenna. The coupled energy should be enough to turn on the chip to communicate with the reader. The inductive coupled energy is achieved by manipulating the near field magnetic field between the antenna body and the inductor loop. To evaluate the performance, the antenna and the inductive feeding loop is designed to operate at RFID UHF band (860 MHz -960 MHz) and simulated using CST software. The antenna body impedance is evaluated to match the impedance of the chip and the loop. It is confirmed that the double loop inductor has higher inductance values and thus should be counted in conjugate impedance between the antenna body and the chip module. The tag with overall dimension of 60 mm x 16 mm can be read at distance at least 9 meters through out the band.

“…Temperature sensors need to be used to monitor and record all critical temperature variations of the cables over a period of time. In different scenarios and environments, many kinds of RFID tag antennas based on dipole or patch type designs have been proposed in literature [4]. However, only a few articles have proposed antennas with the function of temperature measurement for the tags of RFID temperature sensor.…”

A meander line dipole tag antenna used in the radio frequency identification (RFID) system was designed, which can be used for measuring cables' temperature. In order to make the tag antenna fit the cables, an improved tag antenna was designed. The design adopted classical T-matching network, which had a simple structure and achieved impedance matching easily. Input impedance of the proposed antenna is about 33.8+j204Ω, which is conjugate-matched up with a temperature sensor chip which impedance is 36-j198Ω at 915MHz. The simulation results and measurements show that the designed antennas have a wide impedance bandwidth, covering 865MHz to 940MHz band, with dimension of 68mm×32mm. The tag obtains the advantage of low cost and can be mass-produced due to its printed structure. The simulation results of return loss of antenna is-33dB, which can meet the practical requirements of RFID tag antenna. Keywords-RFID tag antenna; impedance matching; UHF band I. Under the hypothesis of polarization matching between the reader and the tag antenna, the RF power required for the microchip electronics turns on and performs backward
