In this paper, a novel methodology to design Ultra High Frequency Radio‐Frequency IDentification (UHF RFID) tag antennas with Barcode layout is proposed with the challenging goal of “fusing” both technologies in a single device. Specifically, after a brief recall of the well‐known barcode standard, a procedure to design meandered barcode‐shaped UHF...

In this paper, we propose a new robust algorithm to improve the localization accuracy without using additional materials. This algorithm is based on a probabilistic approach which only uses the read count (number of detection) of reference and target tags. The localization is performed through two steps. The first step consists of estimating a loca...

This paper presents a novel compact scatterer structure for a passive chipless wireless temperature threshold sensor. The structure is based on a single C-scatterer with multiple embedded slots; each slot forms a sub-scatterer dedicated to resonating in one regulated band. This structure has the advantage of increasing the data capacity without inc...
