“…One of the mainly adopted strategies to stabilize the platformdependent radiation pattern, bandwidth, and input impedance relies on Planar Inverted-F Antennas (PIFA) [14]. Broad bandwidth -usually achieved by means of very-low permittivity substrates -is another well-known technique to realize platform-independent antennas [15].…”

Abstract-The use of Radio Frequency IDentification (RFID) technology in a large array of contexts is a matter of fact. In many cases, such as in robotic applications, the RFID tags should satisfy specific requisites so that read range, platform robustness, radiation properties, cost, and size must be properly taken into account during the design phase. In this work, the specific requirements of tags for RFID-assisted localization and navigation of mobile robots are highlighted and discussed. On such basis, an ad-hoc platform-robust RFID tag is designed, realized and exhaustively tested through both simulations and measurements. The achieved results are impressive and demonstrate the appropriateness of the proposed tag to operate in application scenarios where performance stability is mandatory.

A long range UHF RFID tag with a rectangular metallic cavity structure is proposed for various applications with metallic objects. The proposed tag consists of a rectangular metallic cavity structure and a folded dipole antenna which is located on top of the cavity. The tag is designed for Korean UHF RFID band(910～914 MHz) and the bandwidth, which satisfies the -10 dB input reflection coefficient requirement, is approximately 1.3 %(904～916 MHz). Measurement demonstrates that the proposed tag shows long reading range up to 15 m when it is placed on a metallic plate.Key words: RFID, UHF, Tag, Long Range, Metallic Cavity. Ⅰ. IntroductionAs a rapidly developing technology in automatic identification and data capture(AIDC) industries, radio frequency identification(RFID) has been increasingly used in many applications such as supply chain management, inventory control, security management, and logistics [1] . To meet the requirements for these applications, RFID tags need to be attached on various objects with different shapes and material properties. Therefore, an RFID tag antenna that is attached to a target object plays a crucial role in determining the overall performance of an RFID system. A big challenge in designing a tag antenna is to alleviate the influence of material properties of objects and the presence of other object near the tag [2], [3] . This effect is most severe in UHF band for metallic objects.Planar inverted-F type antennas have been most widely used for applications with metallic objects because they have their own ground planes with which a variation of input impedance can be minimized [4] . In some applications with large metallic objects such as containers, airplanes, ammunitions, and heavy equipment, the reading range should be appropriately extended because the reader and the tag attached on the objects would be remotely located. Therefore, to extend the reading range, an antenna structure providing higher gain should be applied as the tag. Arrays, EBG substrates, and superstrates have been used widely in various applications to increase the gain of antennas [5] . In this paper, we propose a long range UHF RFID tag with a rectangular metallic cavity structure, which is applicable to metallic objects. It is comprised of a folded dipole antenna placed on top of a rectangular metallic cavity structure. The input reflection coefficient, the input impedance, the realized gain, and the radiation pattern of the proposed tag are compared with those of the free standing folded dipole tag and the proposed tag with a metal plate. All simulation data are obtained using CST Microwave Studio [7] .

“…The considerations must be made with the frequency, the impedance of the chip and antenna, the constraints(overall size), the radiation pattern and gain, the reading range, and the tagged objects(geometry and materials). Especially, care must be taken of with regard to the realistic environment that affects the near-field region of reader-and tag antennas and the operational quality of the overall RFID system [1][2][3][4][5][6][7][8][9][10]. Prior to the design of the reader-and tag antennas, the basics of antennas are tapped to see the way the electromagnetic fields propagate from radiators for higher frequency regimes (860MHz-960MHz) along with the magnetic-and electric coupling mechanisms for lower frequency(125kHz-134kHz).…”
