“…Research related to the improvement of electromagnetic characteristics of the RFID passive tags (resonant frequency, the impedance) has been extended by taking into consideration the specific character of the targeted object (shape, size, geometry, composition) and the object operating environment [23,[31][32][33]. The impact of the electrical properties of the substrate material on the performance of the UHF RFID tags is covered in [16]: The dielectric loss factor affects the efficiency.…”

This paper deals with the design and fabrication of durable radio frequency identification (RFID) passive tag with inductive coupling, operating at ultra-high frequencies, dedicated to the identification and monitoring of professional textile products. A reliable architecture for the tag transponder is proposed, featuring a minimal number of galvanic contacts: The two pins of the integrated circuit are connected to the terminals of the inductive coupling loop by using surface mount technology welding. The transponder is encapsulated with an electrically insulating material which is waterproof and resistant to mechanical, thermal, and chemical stress. The antenna is inductively coupled to the transponder through a double loop which substantially reduces the length of the tag and significantly improves the coupling factor, enabling the tag to operate at a low power level. The reliability and flexibility of the tag is obtained by using appropriate materials and manufacturing methods for the ultra-high frequency (UHF) antenna by embroidering a multifilament stainless steel wire on textile support. The washing cycle tests have validated the applicability of this flexible and washable RFID tag, and its electromagnetic performance was experimentally assessed in an independent laboratory.

In this paper, we present a novel compact, coplanar, tag antenna design for metallic objects. Electrically small antenna has designed for a UHF RFID (860–960 MHz) based on a proximity-coupled feed through. Furthermore, two symmetrical Via-loaded coplanar grounds fed by a U-shaped inductively coupled feed through an embedded transmission line. This configuration results in an antenna with dimensions of 31 × 19.5 × 3.065 mm3 at 915 MHz, and the total gain for the antenna is 0.12 dBi. The Via-loaded coplanar and U-shaped inductively coupled feeds allow the antenna to provide flexible tuning in terms of antenna impedance. In addition, a figure of merit is applied for the proposed tag antenna, and the results are presented. The read range is measured to be 4.2 m, which is very close to simulated values. This antenna measurement shows very good agreement with simulations.

“…Semi-active tags are between active and passive tags, as they use power from an onboard battery to operate. However, they still need electromagnetic field generated by reader to "wake up" and transmit the information stored in the tag back to the reader (1)(2)(3) .…”

Objectives: This study introduces a new design strategy for an RFID Tag. Methodology/Findings: A low-profile meander line dipole antenna has been fabricated as a proof of concept due to its electrically small size and simple structure. Good agreement is achieved between the results obtained by this method and those calculated by simulations using CST. The antenna is designed to operate at a frequency of 915 MHz, allocated for UHF RFID. In order to ensure that the design has good performance, all of the antenna parameters are optimized. The results of antenna parameters such as radiation pattern, bandwidth, gain and return loss are also considered. This made it possible to achieve a reduction in size of the order of 40%. Applications: Meander line dipole antennas are useful as radio frequency identification (RFID) tag antennas because of their relatively high radiation efficiency and small size.
