Chipless RFID systems can be considered as a special case of passive RFID systems,
where the tag contains no power source and no electronics. Instead, the tag's information is …

A temperature and humidity chipless RFID sensor is presented in this paper. The tag ID as
well as the two physical parameters are extracted using a traditional chipless RFID tag and …

This paper contains two main areas of research: First, this work outlines a novel, highly
sensitive strain sensor design that should support various levels of deformation, depending …

The ground plane has never been considered as a degree of freedom to be used for
chipless radio frequency (RF) identification (RFID) tag design purposes. For the first time, we …

In this paper, we present the first chipless sensor which does not satisfy the definition of a
linear time-invariant system. This rotational sensor is able to break the time-invariance …

A novel depolarizing chipless tag configuration with high angular insensitivity is presented.
The basic tag comprises two dipole resonators arranged with a relative rotation of 45°. The …

Measurement and response decoding is an ongoing challenge in the chipless radio-
frequency identification (RFID) field. Measurement uncertainties, including tag/reader …

A multitag detection technique is proposed for frequency-coded chipless radio frequency
identification (RFID) to achieve minimum separations of tags, enhanced data capacity, and …

This chapter is a high-level introduction to metamaterials, metasurfaces and frequency-
selective surfaces (FSSs). A brief description of the basic theoretical aspects and possible …

Frequency-coded chipless radio frequency identification (RFID) suffers from resonant
frequency detuning caused by misaligned orientations. The literature has employed …
