“…The peak gain of the antenna is 1.52 dBi, and the measured maximum reading distance is 6.3 m at 915 MHz. The performance factors for the proposed tag antenna, such as size and gain, are better than those of other small tag antennas [5][6][7].…”

In this article, a compact tag antenna for UHF RFID systems is proposed. The proposed antenna consists of a T-matching network, meandered dipole, and an inverted-U shaped parasitic element. The tag antenna is miniaturized by utilizing inductive coupling between the meandered dipole and the parasitic element. The overall dimension of the proposed tag antenna is 17.96 Â 35.6 mm 2 . It has a gain of 1.52 dBi and a maximum reading distance of 6.3 m at 915 MHz. The size of the tag antenna is about 33% of that of other RFID tag antennas, such as a meander line antenna and a coplanar inverted-F antenna. In spite of its small size, the proposed tag antenna yields superior performance.

“…It seems to be habitual to design the impedance of the tag antenna to the conjugate value of the impedance of chip, because it can deliver the maximum power to the chip [3], [4], [5]. However, this paper proves that for the sake of achieving largest delta RCS, impedance-matching design is not the optimal method, yet mismatching design method could get larger delta RCS and ensure the stability of the system.…”

This paper presents an original design method (mismatching design method) for RFID tag antenna application through the analysis of the Radar Cross Section (RCS) in RFID system. This design method can achieve the largest delta RCS than traditional way so that it optimizes the stability of the RFID system. The Thevenin equivalent circuit model of the tag antenna is discussed which displays the limit of the mismatching design method. Finally, a design example is given by using the method presented and the result verifies the validity of the analysis in this paper.

“…However, there are some problems that must be overcome for UHF label tags attached on the surface of metallic objects due to the electromagnetic wave scattering from the metal plane. Some metal tag antennas have been presented by using planar inverted-F antenna (PIFA) structures [1], [2], a dipole antenna [3], slits structure [4]- [7], a T-matching network [8], and a planar inverted-E antenna [9]. However, the above presented designs need larger dimensions of a tag antenna that is unable to meet the dimension consideration of the product.…”

A novel broadband design of planar tag antenna mounted on the metallic objects for the UHF radio frequency identification (RFID) system is proposed. We derive a new resonant mode that is excited with frequency shifting to enhance the operating bandwidth for broadband operation by employing the shorting pins posted at the corner of the proposed tag antenna. The obtained impedance bandwidth across the operating band can reach about 112 MHz (12.5%) for the UHF band, which is from 850 to 962 MHz. Also, with unidirectional pattern, the measured reading distance is about 5.2 m as the proposed tag antenna mounted on the metallic object.Index Terms-Broadband, radio freqnency identification (RFID), tag.
