“…Others have improved upon the PIFA by incorporating loaded inductive elements to modify the distribution of the antenna's capacitance and inductance. Additionally, employing PIFA arrays can alter the antenna's radiation pattern, thereby minimizing the impact of metal objects [11]. Lee and colleagues have advanced research on metal-resistant antenna structures by adopting an annular feeding method to evenly guide the current onto the PILA structure.…”

Amidst the rapid expansion of e-commerce and the consequential surge in industries such as transportation, logistics, and supply chain management, there has been remarkable growth. Radio Frequency Identification (RFID) technology, along with its associated tags, plays a pivotal role in the transmission and tracking of crucial information within these sectors. However, the presence of metallic components within RFID systems poses a significant obstacle to efficient antenna transmission. Consequently, there is a pressing need for the development of RFID tag antennas endowed with metal-resistant properties. This paper undertakes a comparative analysis of existing designs and structures for metal-resistant RFID tag antennas, providing valuable insights into their prospective developmental trajectories and potential applications. Such analysis serves as a pertinent reference for research and engineering endeavors across related domains.

“…Proper impedance matching and high read range properties are desired in multiband RFID tag antennae [6]. Various dual band tag antennae have been reported in the literature, and these antennae employ different techniques such as F-shaped monopole RFID tag working at microwave frequency [7], conjoining PIFA and meandered microstrip patch antennae for both UHF and microwave frequencies [8], incorporating bent feedlines between concentric microstrip circular rings [9], conventional planar dipole tag with T-matching networks [5], and two distinct antennae for receiving and backscattering operations [10]. Additionally, the tag can be attached to any surface directly, and therefore metal compatibility is one of the major criteria for designing the tag antennae.…”

This paper presents an effective way to design an RFID tag antenna to operate at three different frequencies by incorporating a switching technique. PIN diode has been used to switch the RF frequency because of its good efficiency and simplicity. The conventional dipole-based RFID tag has been improvised with added co-planar ground and PIN diode. The layout of the antenna is designed with a size of 0.083 λ0 × 0.094 λ0 at UHF (80–960) MHz, where λ0 is the free-space wavelength corresponding to the mid-point of the targeted UHF range. The RFID microchip is connected to the modified ground and dipole structures. Bending and meandering techniques on the dipole length help to match the complex chip impedance with the dipole impedance. Additionally, it scales down the total structure of the antenna. Two PIN diodes are placed along the dipole length at appropriate distances with proper biasing. The ON-OFF switching states of the PIN diodes enable the RFID tag antenna to switch over the frequency ranges (840–845) MHz (India), 902–928 MHz (North America), and 950–955 MHz (Japan).

“…e planar inverted-F antenna (PIFA) using the metallic surface as ground plane is a popular structure for designing miniature metal tags. By applying the PIFA design concept, the antenna size can be easily reduced by introducing vias [16,17], but the performance of a PIFA is significantly more sensitive to the position of the vias [18]. In this paper, a new type of L-shaped antenna is used for designing a novel 3D tag antenna that can be mounted on a metal object for IoT RFID applications.…”

In this paper, a novel 3D planar inverted-L antenna (PILA) Ultrahigh Frequency (UHF) Radio Frequency Identification (RFID) tag mountable on metallic surfaces is proposed for the Internet of Things (IoT) indoor localization applications. The proposed tag antenna (45 mm × 82 mm × 4 mm or 0.137λ × 0.25λ × 0.012λ) is designed for mounting on metallic objects. The 3D PILA antenna is fabricated using a copper sheet of thickness 1 mm and air as the dielectric substrate in order to minimize costs for materials and realization. In the design, T-slot has been inserted in the radiating element for tuning of the tag’s resonance for achieving good matching with the chip. Also, a simple equivalent circuit model has been obtained to analyze the impedance of the 3D PILA. Based on the optimized design, the fabricated prototype has been measured in the anechoic chamber. The resonant frequency of the proposed tag is stable, and it is not affected much by the metallic object. The measurement results of the antenna prototype demonstrated a reasonable agreement with the simulation results, and a read range of 3.6 m was measured inside an anechoic chamber. Most importantly, in the building hallway, the proposed tag is able to achieve a maximum read distance of 18 m with a transmitted power of 31.5 dBm at 867 MHz when placed on metal. With the 3D PILA antenna structure, the proposed antimetal tag is a suitable solution that can be integrated into an indoor localization scenario.
