Radar cross-section measurement in millimetre-wave for passive millimetre-wave identification tags
IET Microwaves, Antennas and Propagation, 2015 The passive millimetre‐wave identification (MMID) technology was introduced few years ago, exploiting the advantages of the passive ultra‐high frequency (UHF) radio frequency identification (RFID). The communication is based on backscattering modulation, related to the radar cross‐section (RCS) of the transponder.
