Notice of Removal: RFID Integrated Circuits as Network Controllers

This paper presents a novel approach for controlling reconfigurable antennas using passive Radio Frequency IDentification (RFID) Integrated Circuits (ICs) physically connected to the RF power generator through transmission lines. Selective activation of each IC enables signal path management in a passive and low-cost way. The feasibility of the idea is demonstrated by designing and testing a custom PCB equipped with 4 RFID ICs. Measurement results show the successful equal distribution of the input power among the ICs and their ability to dynamically control the signal routing. Each IC provides two programmable output voltage levels, 0 V and 1.8 V, enabling <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$N$</tex>-bit reconfigurability within the guided structure, where <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$N$</tex> corresponds to the number of ICs. The proposed architecture significantly reduces the system's cost, power consumption, and complexity compared to traditional reconfiguration mechanisms, where external controllers and power supplies are required.
