In this paper we present a technique allowing to identify harmonic transponders. The approach relies on the evolution of the backscattered power at a given harmonic frequency as a function of the fundamental frequency. Thus to identify an harmonic transponder, the associated reader sweeps a continuous wave in the considered bandwidth. Experiments are done based on a vector network analyzer, the method is able to identify two different RECCO reflectors. A study on the read range is also included. These harmonic transponders allow to drastically increase the read range compared to the one associated to linear timeinvariant systems such as chipless tags.

Harmonic transponder sensors, receiving radiofrequency (RF) signal and converting it to a modulated second harmonic, have been demonstrated to be effective for signal interrogation in environments with strong clutters. Here, we propose a compact dual-resonance microstrip antenna consisting of an elliptical patch loaded with shorting pins. Such an antenna utilizes the TM e110 resonant mode to intercept the perpendicularly-polarized fundamental tone (2.86 GHz) and uses the TM o110 resonant mode to retransmits the parallelly-polarized second harmonic (5.72 GHz). Moreover, we have developed a harmonic-based wireless liquid sensor comprising the proposed antenna and a micromachined liquid channel. Our measurement results show that even in the noisy environment, the second harmonic strength can precisely indicate the dielectric property of liquid filled in the microfluidic tank (e.g., acetone-water mixtures with various concentrations). However, a similar setup without frequency and polarization modulations (i.e., linear and passive backscatter tag) fails to provide a sensitive and quantitative measurement of liquid property. The proposed low-profile dual-resonance antenna with sensing capability will pave the way for the development of harmonic sensors and nonlinear radio-frequency identification (RFID) tags.

“…Thus, the reading range can be extended with a low-cost component. 3,4 However, when a tag antenna is placed on or close to metal objects, antenna performance degrades because of its material characteristics, which negatively affects fundamental antenna properties including input impedances, power transmission coefficients (PTC), gains, and radiation patterns. Several methods have been suggested to overcome this problem and improve tag performance.…”

This paper describes an ultrahigh frequency (UHF) tag antenna mounted on a metallic plate for radio frequency identification (RFID). The impedance of the proposed antenna can be tuned using various methods. The compact patch antenna consists of a C-shaped resonator and a ground plane connected to a small shorting wall and is connected to a feeding loop in the middle of the Cshaped resonator. Etching a couple of slits close to the shorting wall and a slot in the center of the C-shaped resonator provided a flexible method for adjustment to match the conjugate impedance with the UCODE 8/8 m chip (13 − j191 Ω at 915 MHz). The optimal design with an overall size of 30 × 30 × 3 mm 3 (0.092 λ 0 × 0.092 λ 0 × 0.0092 λ 0 ) yielded a high power transmission coefficient of 91% and reading range of 6.4 m for the effective isotropic radiated power (EIRP) of 4.0 W when the tag antenna was mounted on a 220 × 220 mm 2 metal plate. The proposed antenna was designed at standard frequency bands of the Federal Communications Commission (FCC, 902-928 MHz) for North America and Taiwan. Antenna fabrication and testing were performed, which revealed that the measured data were in good agreement with the simulation results.
