“…In [16], the authors used polymer to build liquid antennas. The other most common polymer materials that are being widely used are PET, PDMS [17,18], and polyimide [19]. These substrates have gained significant attention due to their lossless flexible properties, and the thickness is also mentionable less.…”

The rapid growth of wearable technologies within wireless body area networks (WBANs) has increased the demand for advanced wearable antennas. The human body's presence creates significant challenges for these antennas since it behaves differently as a wave propagation medium. It is necessary to prioritize specific requirements for antenna design, such as size, frequency, efficiency, wideband and multiband operation, because of body interaction and signal attenuation. The development of novel methodologies, the use of state-of-the-art fabrication methods, and the advancement of antenna designs have been the main areas of attention for researchers in this field in recent years. This research investigates contemporary advancements in wearable antennas, particularly emphasizing utilizing recent materials, fabrication processes, and new techniques. It also highlights the unique applicability of these antennas in advanced WBAN systems.

“…In [7], a single layer tag antenna, consisting of a folded dipole integrated with outer strip lines, has been designed to achieve increased inductance for impedance matching, but its bandwidth and radiation efficiency were low. The foam-attached tags in [8] and [9] have been constructed from the label-type dipoles with a spacer, in order to reduce the effects of the backing metallic surface. These tags showed otherwise (i.e., in the absence of spacer) a significant deterioration in the radiation performance.…”

Miniaturized Metal-Mountable U-Shaped Inductive-Coupling-Fed UHF RFID Tag Antenna With Defected Microstrip Surface

This study presents a novel miniature ultra-high frequency (UHF) radio frequency identification (RFID) tag for metallic objects. Its arrangement includes a U-shaped feeder, which is inductively coupled to two E-type connected patches. Size reduction is achieved by means of utilizing the U-shaped feeder, and introducing a defection in the connection between the two E-type patches. The defection in the connection area between the patches modifies the current distribution by increasing the electrical length, and the antenna inductance. Furthermore, increasing the length of the U-shaped structure significantly raises the antenna inductance and, consequently, the flexibility of the structure for the impedance matching purpose. Polytetrafluoroethylene (PTFE) is employed for the fabrication of the designed tag. The tag's size is 65 mm × 20 mm × 1.5 mm, and does not require any complex fabrication process such as utilization of metal vias and/or shorting stubs. It is observed that with 4W EIRP, the measured detection distance is 6.9 m when it is attached onto metal sheets (20 cm × 20 cm), and 5.54 m when it is in free space. The measurement results also are in good agreement with the simulated results.INDEX TERMS Defected microstrip surface, impedance matching, metal mountable tag antenna, miniature UHF tag antenna.

“…The resonance response of the antenna encompasses just a part of the UHF RFID band. Polyethylene terephthalate (PET) is used to create a structure that is flexible and thin for the RFID tag antenna in [ 6 ]. A narrow resonance response is discovered in the antenna’s simulation, which has a tendency to shift to 900 MHz in the measured outcome.…”

This paper addresses the performance evaluation of a modified square loop antenna design for UHF RFID applications that is excited through a narrow feed line connected to a square loop, an impedance matching network. The square loop dimensions are modified to reach a conjugate impedance matching. A gap is fixed between the feed-lines to link the chip. To achieve impedance matching, the structures of the feed-line are optimized accordingly. In addition, the antenna consists of a straightforward geometry. An 11.9-meter maximum read range is achieved using a compact size of 80 × 44 mm2 and 3.2 W for the effective isotropic radiated power. Additional findings reveal that the proposed tag antenna is able to provide a stable resonance response in the near field of a large metallic surface.
