1. An object detection system comprising:

  • a reader waveguide formed as an open transmission line;

    an RFID tag placed above the reader waveguide, the RFID tag being placed in such a manner that a positional relationship between the RFID tag and the reader waveguide is predetermined regardless of a presence or an absence of an object;

    a signal strength acquisition unit that acquires signal strength of a read signal read from the RFID tag by electromagnetic coupling through the reader waveguide; and

    an object detection unit that detects physical characteristics of the object corresponding to the acquired signal strength based on a relationship between three or more values of signal strength of the read signal and physical characteristics of the object to be detected.
