Abstract-UHF passive Radio Frequency Identification technology is rapidly evolving from simple labeling to wireless pervasive sensing. A remarkable number of scientific papers demonstrate that objects could be in principle remotely tracked and monitored in their physical properties all along their daylife. The key background is a new paradigm of antenna design that merges together the conventional communication issues with more specific requirements about sensitivity to time-varying boundary conditions. This paper proposes a unified introdution to the tag-as-sensor problem with particular care to formalize the measurement indicators and the communication and sensing trade-off, with the purpose to understand and classify the state of the art and definitley provide a knowledge base to face a large variety of emerging applications.

“…By applying an elongation, the shape of the tag will turn from a tightly-twisted meander to a zig-zag dipole, thus altering the antenna properties, such as the ratio of the actual backscattered power to the one measured during the steady state [34].…”

“…Therefore, the study of broadband miniaturization of dual-polarized antennas has become a research hot spot. In essence, the general methods of miniaturization are to take a dielectric substrate with a high dielectric constant [8], extend path of flowing [9,10] and to introduce reactance elements [11] or shorting probes [12]. But the effect of these methods on miniaturization of dual-polarized dipole antennas is not obvious.…”

Abstract-Artificial magnetic conductor (AMC) is a periodic structure with in-phase reflection, which can be used in dual-polarization dipole antenna to reduce profile height. In this study, a low-profile dual-polarized dipole antenna with an AMC reflector is proposed by improving the AMC structure. The antenna consists of a pair of orthogonal planar dipoles with U-shaped slots, two T-shaped feeding lines, and an AMC reflector. The overall height is 0.132λ 2.2 GHz . Experimental results show that the proposed antenna has a wider bandwidth than other antennas of the same type. The impedance bandwidth of this antenna is 52% (1.65 GHz to 2.81 GHz), and the proposed antenna also has the advantages of low profile, high port isolation (< −30 dB), and low cross polarization (< −27 dB). These features can meet the current needs of the telecommunications industry.

“…A printed RFID patch antenna has been shown to measure high strain with change in antenna gain and impedance (Merilampi et al, 2011). Meanwhile, Occhiuzzi et al (2011) demonstrated the relationship between strain and electromagnetic behaviours of a meander-line RFID antenna sensor. In order to reduce the size of an RFID patch antenna sensor, Yi et al (2011) proposed an antenna folding technique using vias and validated the performance of the folded patch antenna sensor by tensile experiments.…”

Passive (battery-free) wireless patch antenna sensors have been developed in recent years for strain sensing, to provide convenient and low-cost instrumentation. Despite past efforts, current analytical and experimental studies have mainly focused on performance in single-axial measurement, which is simple and unrealistic from typically encountered arbitrary plane stress fields. This paper presents strain sensor rosettes made of folded patch antennas and slotted patch antennas for measuring an arbitrary surface strain (plane stress) field. The transverse strain effect of both sensors is discussed and has been validated through laboratory experiments. Multiphysics coupled simulation is conducted to describe accurately the mechanical and electromagnetic behaviours of antenna sensors.Resonance frequency shifts of the antenna sensors are used to derive the three strain components in an arbitrary plane stress scenario -that is, two normal and one shear strain components. Both numerical studies and experimental validations have been performed.
