One key element of a chipless RFID system is the tag. Since it is chipless, it acts both as the scatterer and encoder. As the scatterer, it needs to reradiate the incident field as much as possible in order to maximize signal-to-noise ratio (SNR) in the reader. As the encoder, it needs to encode a high density of data on the backscattered signal. There

A Chipless Piezoresistive Strain Sensor
2023 17th European Conference on Antennas and Propagation (EuCAP), 2023Strain sensors are widely used in various applications and, depending on the specific application, it is necessary they operate completely wireless. The first step for the realization of a wireless strain sensor is the choice of the transducing material. Piezoresistive materials, whose surface impedance varies when a mechanical stimulus is applied, are

2018 48th European Microwave Conference (EuMC), 2018
In this paper a compact wearable chipless tag is presented. The proposed tag is based on a frequency signature achieved by using a microstrip line loaded by compact resonators slotted in the ground plane. Textile materials have been used for both the substrate and the conductive parts.

Chipless RFID Tag Localization
IEEE Transactions on Microwave Theory and Techniques, 2013A novel localization technique for frequency-domain chipless RF identification (RFID) tag is proposed. A short-duration ultra-wideband impulse radio signal interrogates the tags, and multiple receivers in the interrogation zone capture the backscattered signal from the tags.

Chipless RFIDs by using metasurfaces
The 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014High-Impedance Surfaces comprising multi-resonant elements are proposed as chipless tags. The presence of the ground plane in the structure is a key point in realizing a chipless RFID nearly insensitive with respect to the objects which the tags are placed on.
