Abstract
Reconfigurable Intelligent Surfaces (RISs) are surfaces composed of sub-wavelength elements integrated with tunable electronic circuits. Typically, to control RIS elements, a bias voltage is applied to each element through Field-Programmable Gate Arrays (FPGAs) which, unfortunately, have some limitations like high cost, high power consumption, and limited wireless connectivity. One potential alternative to FPGAs is Radio Frequency Identification (RFID) technology since it is a low-cost, and low-power solution that can provide wireless connectivity. In this paper, we investigate the feasibility of wirelessly reconfiguring the response of an RFID antenna acting on the configuration of another antenna exploiting the switching capabilities of a PIN diode. For the sake of simplicity, the early proposed model is made up of two RFID antennas: the first one must be equipped with an RFID chip capable of powering external devices, while the second one with a standard commercially available chip and a PIN diode to achieve reconfigurability. The diode modifies the impedance matching of the second RFID IC enabling wireless reconfiguration of the system. The concept can be easily extended to more than two elements for achieving reconfigurable ID responses, radiation patterns and eventually sensing activity.
