Advances in Wirelessly Powered Backscatter Communications:
This article will introduce the state-of-the-art antenna design and radio frequency (RF) system integration for wire-lessly powered backscatter communications, covering both the node and the base unit.
Integrated Sensing and Backscatter Communication
This system comprises a full-duplex base station (BS), a backscatter tag, and a user. The tag reflects the BS transmitted signal and provides data to the user. The BS extracts
Backscatter Communications
Extending backscatter communication ranges can be realized using high gain retrodirective arrays and BFNs-based RFID architectures as presented in the previous section.
A survey on ambient backscatter communications: Principles, systems
We first present the basic principles of ambient backscatter communications covering architecture, basic techniques, and primer knowledge of ambient signals. After that, we provide a
