The RFID tag system includes an RFID tag and an RFID reader/writer. The RFID reader/writer includes a transmitter that transmits a circularly-polarized radio wave to the RFID tag, a receiver that separately receives horizontal and vertical polarization components of a return wave from the RFID tag; and a received signal combiner that logically combines signals separately received by the receiver. The received signal combiner includes an optimum combiner that combines the horizontal polarization component and the vertical polarization component such that an S/N ratio of the received signal is enhanced compared with the case that the horizontal polarization component and the vertical polarization component are separately received."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"RFID tag system and RFID reader/writer","description":"An aspect of the present invention provides an RFID tag system in which a null point is hardly generated.
