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 a transmission line to achieve RF signal path management. The feasibility of selectively activating the ICs through a wired link is demonstrated through the design and test of a custom PCB equipped with four ICs. Compared with traditional reconfiguration mechanisms, where external controllers and power supplies are required, the proposed architecture significantly reduces system cost, power consumption, and complexity, particularly in space-constrained applications.
