In this paper we investigate the possibility to jointly adopt millimeter-wave technology with passive RFID based on backscattered signals, which paves the way to new identification and localization applications for next 5G scenarios. In particular, we assess the feasibility of this solution by comparing it with the passive RFID in the microwave UWB band. Results show that, despite the high path-loss at 60 GHz, it is possible to achieve interesting performance thanks to the less stringent requirements in terms of emitted power with respect to the UWB technology. Moreover, the possibility of localizing tags with a single reader is foreseen thanks to the adoption of narrow-beam antennas and beamsteering operations.
