Radio-frequency identification (RFID) sensors are one of the fundamental components of the internet of things that aims at connecting every physical object to the cloud for the exchange of information. In this framework, chipless RFIDs are a breakthrough technology because they remove the cost associated with the chip, being at the same time printable, passive, low-power and suitable for harsh environments. After the important results achieved with multibit chipless tags, there is a clear motivation and interest to extend the chipless sensing functionality to physical, chemical, structural and environmental parameters. These potentialities triggered a strong interest in the scientific and industrial community towards this type of application. Temperature and humidity sensors, as well as localization, proximity, and structural health prototypes, have already been demonstrated, and many other sensing applications are foreseen soon. In this review, both the different architectural approaches available for this technology and the requirements related to the materials employed for sensing are summarized. Then, the state-of-the-art of categories of sensors and their applications are reported and discussed. Finally, an analysis of the current limitations and possible solution strategies for this technology are given, together with an overview of expected future developments.

“…The removal of the IC allows achieving numerous advantages such as the reduction of the production costs, the operation in harsh environments and the compatibility with wearable and printable electronics [2]. Similarly to conventional RFID [3], chipless RFID technology can be employed in scenarios where sensing capabilities are also required [4]- [7].…”

The performance of different chipless RFID tag topologies are analysed in terms of Radar Cross Section (RCS) and Bit Error Rate (BER). It is shown that the BER is mainly determined by the tag Radar Cross Section (RCS) once that a standard reading scenario is considered and a fixed size of the tag is chosen. It is shown that the arrangement of the resonators in the chipless tag plays a crucial role in determining the cross-polar RCS of the tag. The RCS of the tag is computed theoretically by using array theory where each resonator is treated as a separate scatterer completely characterized by a specific reflection coefficient. Several resonators arrangements (periodic and non-periodic) are compared, keeping the physical area of the tag fixed. Theoretical and experimental analysis demonstrate that the periodic configuration guarantees the maximum achievable RCS thus providing a global lower BER of the chipless RFID communication system. We believe that the BER is the more meaningful and fair figure of merit for comparing the performance of different tags than bit/cm 2 or bit/Hz since the increase of encoded information of the tag is useful only if it can be correctly decoded.

“…Orientation estimation is however limited to a range of 45 • . Finally, in [13] authors consider the same finite periodic surface but with a scatterer composed of 4 different dipoles to determine the orientation. All these methods exploit the magnitude of the backscattered signal at the resonant frequency, and are thus sensitive to the distance between the antenna and the tag.…”

This paper presents theoretical and practical implementation of the chipless RFID technology to measure the orientation of tags attached on a 2D surface. Analytical expressions are used to recover tag orientation from mono-static co-polarization measurements. Simulations are performed to validate the orientation estimation technique. Moreover, measurements in anechoic chamber and real environment are done to evaluate the performance of the proposed solution. Contrary to already implemented techniques, the one introduced in this paper is not sensitive to distance variations which is an advantage for practical applications. Our solution can estimate the orientation of a chipless tag with an error less than 5 • in a range of 90 • .
