mm-Wave Chipless RFID Tag for Healthcare Applications

2020 XXXIIIrd General Assembly and Scientific Symposium of the International Union of Radio Science, 2020
The work proposes the use of mm-wave chipless tag to be used in healthcare applications. A chipless tag at 24 GHz based on a cross-polarized Van Atta retrodirective array has been designed with the aim to show the practical feasibility of the proposed system.

Chipless RFID tag for light sensing

2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014
A fully passive chipless RFID tag with light sensing capabilities is presented for low-cost, maintenance-free applications. This paper describes the steps towards developing a prototype of passive light sensor using off the shelf photoresistors. Results show a single microwave resonator has 60 MHz frequency shift and 7.5 dB power variation for 0 to ...

Identification of Chipless RFID Tags in the Reader

2014
The signal received by the antenna includes the scattered signal from the chipless RFID tag located in the reader area, reflections from background objects (clutter), and noise. Therefore, the detection process is a challenging aspect in the design of chipless RFID systems.

Simple Chipless RFID Tag Configurations

2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP), 2018
Two unique configurations of chipless RFID tag are reported in this paper. They consist of integrated Lresonators and cross polarized transmitting and receiving circular patch antennas. The validations of the proposed designs have been carried out using 8-bit data encoded tags, for the frequency band of 3.3–5.8 GHz, and microstrip circular antenna ...

Chipless RFID Tags: Co- or Cross-Polar Tag?

2019 IEEE Asia-Pacific Microwave Conference (APMC), 2019
This paper provides a comparison between two types of co- and cross-polar frequency-coded chipless RFID tags considering their electrical parameters. These parameters are the level of radar cross section (RCS), data capacity, rotation sensitivity, and resistant to interferences. A brief description of each parameter is given.

A Cross-Polar Orientation Insensitive Chipless RFID Tag

2019 IEEE International Conference on RFID Technology and Applications (RFID-TA), 2019
Recently, Chipless RFID systems have been developed significantly and going to become commercialized in the near future. One of the critical challenges in chipless RFID systems is eliminating high reflections from the items behind the tag, which caused interference in the tag ID measurement process.

Screen printed chipless RFID tags

Proceedings of the 2014 37th International Spring Seminar on Electronics Technology, 2014
Radio Frequency Identification (RFID) is the technology that is used in the daily life. A RFID system consists of RFID tags and readers including many electronic passive and active components. This article deals with design of chipless RFID tags that are screen printed on flexible substrates and do not need any electronic components for their function.

Chipless RFID Tag-Reader System

2012
In this chapter, we present the integration of the chipless RFID tag and RFID reader presented in the preceding chapters into a system. The implementation constraints in terms of reading range, tag orientation and operating frequency are specified. Specific components of the RFID reader’s digital control section along with the tag ID detection/decoding

A Contactless RFID System Based on Chipless MIW Tags

IEEE Transactions on Antennas and Propagation, 2018
In this paper, a contactless RFID system formed by chipless tags based on the magneto-inductive wave (MIW) delay lines is proposed. In order to carry out the reading process, two reader probes have been designed, manufactured, and measured: the first one based on an axial to planar MIW transition and the second one based on a printed monopole. Moreover,
