Flexible substrates have become essential in order to provide increased flexibility in
wearable sensors, including polymers, plastic, paper, textiles and fabrics. This study is to …

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 …

In this paper, a compact and fully passive bit encoding circuit, capable of operating as a
chipless radio frequency identification (RFID) tag is presented. The structure consists of …

This article presents a cost-efficient flexible chipless radio frequency identification (RFID) tag
with wireless humidity sensing, which is fabricated by in situ metallization and inkjet printing …

This paper presents a unique geometry of a chipless radio frequency identification (RFID)
tag for encoding a large number of bits in a very small form factor. The tag geometry consists …

In this paper, we first carry out an in-depth review of the performance parameters of
frequencydomain chipless RFID transponders in terms of their spatial density, spectral …

A fully inkjet-printed flexible chipless RFID tag is presented in this paper. It is based on a
coplanar waveguide (CPW) coupled to a multiresonator circuit to encode the information in …

This work presents a cross-polar dual-layer chipless radio-frequency identification (RFID)
tag based on a ladder-shaped resonator design. An integrated ground plane enables direct …

Increasing competitiveness, as well as levels of sustainability, are some of the main
challenges that the packaging sector is facing. The introduction of information and …

This paper presents the design, fabrication and testing of two embroidered chipless
octagonal-shaped RFID tags on cotton fabric for wearable applications. The first tag is …
