Abstract

In this paper, we present a novel chipless RFID-based passive fluid sensor platform which enables a reliable remote fluid identification. The proposed sensor platform consists of a capacitive gap-loaded tunable filter for fluid sensing and two broadband perpendicularly polarized microstrip monopole antennas for a dual-polarization wireless interrogation approach, that allows for drastically reduced ambient clutter interference. Two different fluids (acetone and water) are tested to verify the exceptional sensing capability of the proposed platform, while inkjet-printing technology has been used for its low-cost conformal implementation.
