Chipless Radio Frequency Identification (RFID) has been used in a variety of remote sensing applications and is currently a hot research topic. To date, there have been a large number of chipless RFID tags developed in both academia and in industry that boast a large variation in design characteristics. This review paper sets out to discuss the various design aspects needed in a chipless RFID sensor. Such aspects include: (1) Addressing strategies to allow for unique identification of the tag, (2) Sensing mechanisms used to allow for impedance-based response signal modulation and (3) Sensing materials to introduce the desired impedance change when under the influence of the target stimulus. From the tabular comparison of the various sensing and addressing techniques, it is concluded that although many sensors provide adequate performance characteristics, more work is needed to ensure that this technology is capable/robust enough to operate in many of the applications it has been earmarked for.

“…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).

“…Recently, UHF and ISM bands have become more attractive because of their suitability for long-range applications and reconfigurability [1][2]. The dual-band antennas developed conform to various communication protocol standards and established operating frequency bands in one system [3][4][5][6]. For that reason, more designs of dual-band antennas for RFID readers were developed to fulfill the requirement of the RFID industry.…”

<p>This paper focuses on the design and fabrication of dual band antenna for UHF RFID and ISM RFID applications. The U-shaped patch loaded with dipole is introduced and investigated. The antenna can be performed dual-band frequencies at 0.915 GHz and 2.4 GHz required in RFID applications with reflection coefficient is less than -10 dB. The lower band can be varied by adjusting both dipole arms length and upper band is tuned by U-shaped patches. The gains of the design with a size 130 45 1.6 mm3 are performed 1.89 dB and 3.65 dB for single and dual band respectively. This compact and low cost dual band antenna also performed total efficiency greater than 80%. The design methodology and antenna measurement results are both presented and discussed in this letter.</p>
