“…Whereas the earlier design was made on a single‐sided PCB of FR4 substrate having

= 4.4, tan

= 0.02, and thickness 1.54 mm with copper deposition of 20 microns, the bendable tag was made on a single‐sided polyimide substrate having

δ

= 0.008, and thickness 0.05 mm with copper deposition of 10 microns. As with Reference 34, a meander‐line technique 38 is used to increase the electrical length of the antenna and using nonuniform lines (track width and length) with smooth corners. The tag antenna was matched with an EPC global Class 1 second generation Higgs‐4 chip 37 having input impedance 21.55‐j191.45

“…Therefore, not suitable for inventory cloth tags. In this article, to comply with the expectations immediately described, a bendable UHF RFID tag antenna using nonuniform meandered lines for retail garments in the textile industry is presented and compared with an earlier design 34 (made on FR4). The relatively low‐cost tag is a wide band, compact, and good conjugate matching with a good read range.…”

A bendable ultra‐high frequency (UHF) radio‐frequency identification (RFID) tag antenna using nonuniform meandered lines for retail garments in the textile industry is presented. Based on an earlier UHF RFID tag antenna using nonuniform meandered lines, the proposed tag is fully bendable and aimed to be embedded in retail garments for long‐life cycles. As a result, a relatively low cost, wideband, compactness, and good conjugate matching with good dipole‐like read range is presented. Results showed an antenna with a wide bandwidth of 900 MHz and a long read range of 10.1 m making the UHF RFID tag antenna using nonuniform meandered lines a potential candidate for retail garments in bendable applications of the textile industry. Simulations are corroborated by measurements and are in fairly agreement.

A flexible radio frequency identification (RFID) tag antenna with a T-match feeder is proposed in this paper. The T-match feed acts as the conjugate network matching of the tag antenna and 0.99 of power transfer coefficient was achieved. By incorporating a meander line and capacitive tip loading technique, the compact size is realized with a wide bandwidth of 44MHz that can cover the RFID spectrum allocated for the Malaysia region, from 919 to 923 MHz. The proposed antenna is printed on the flexible polyethene terephthalate (PET) substrate with a dimension of 90mm × 24mm × 0.143mm. By employing 4W EIRP power, the detection distance of 29.15m in free space. The proposed meandered line and capacitive tip loading tag antenna with T-match feed line is beneficial to be part of the RFID systems because of their compactness, wide bandwidth and high-power transfer coefficient.

A compact, flexible, long-range, and impedance transformer balun-like integrated UHF RFID tag antenna is proposed for the detection of water bottles. To alleviate the performance of a tag antenna in close proximity to a high dielectric material such as water, the radiating element of the tag antenna uses folded, unbalanced strips made of balun-like arms wrapped around the tag's body. As a result, a wide bandwidth with reasonably good radiation resistance is achieved. The tag's body comprises dual-loops for the impedance matching to the tag chip. This leads to a long read range of 13.33 m; > 5.83 m compared to other state-of-the-art designs. The proposed tag antenna conforms to a small footprint by wrapping the balun-like arms around the tag's body, which results in a compact form. The tag is fabricated, and the results reasonably agree with simulations.
