Abstract: Systems and methods related to a RFID-based smart confined environment are provided. A system for localizing an object in a smart home includes a single RFID reader, a plurality of passive RFID tags, each of which is affixed to one of a plurality of objects to be located and contains information of a corresponding object, and a mobile platform including two antennas configured to transmit a carrier wave signal and receive a backscattering signal from a target object. The two antennas are parallelogram-shaped and abutted against each other along a radiation direction.
