In recent few years, the antenna and sensor communities have witnessed a considerable
integration of radio frequency identification (RFID) tag antennas and sensors because of the …

Chipless Radio Frequency Identification (RFID) has been used in a variety of remote
sensing applications and is currently a hot research topic. To date, there have been a large …

Though commonly used to calculate Q-factor and fractional bandwidth, the energy stored by
radiating systems (antennas) is a subtle and challenging concept that has perplexed …

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 …

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 …

Chipless RF identification (RFID) technology has emerged as an alternative to RFID systems
that have tags equipped with silicon integrated circuits (ICs), or chips [1]-[12]. The main …

This letter presents a compact dual-polarized chipless tag. The chipless tag consists of
nested concentric coplanar square loops, and adjacent loops are connected by two stub …

In this paper, an open-loop resonator with fragment-loading structure is used for the first time
in the design of radar cross section-based chipless radio-frequency identification (RFID) tag …

This paper presents a novel frequency coded chipless RFID tag, which exploits the
backscattered co-polarized and cross-polarized responses from a tag illuminated with a …

Radio frequency identification (RFID) is one of the most modern technologies in
identification and tracking systems. Recently, chipless RFID tags have been invented as a …
