摘要：
A radio frequency identification (RFID) smart shelf system manages a product through communication with an RFID tag that is attached to the product on a shelf, and includes an RFID reader, a plurality of reader antennas, and an RF switch that is connected between the RFID reader and the plurality of reader antennas. The RF switch periodically varies a phase difference between RF signals of a portion of a plurality of output connection ports that set a connection to each of the plurality of reader antennas.
