  • Publication number: 20190180063
    Abstract: A wireless tag reading apparatus includes an input control means, an extraction means, a storage control means, and a determination means. The input control means receives an input of a signal obtained by converting the radio wave received by an antenna that receives a radio wave from a wireless tag. The extraction means extracts the phase of the radio wave received by the antenna from the signal received by the input control means. The storage control means causes the storage medium to store the phase of the radio waves extracted by the extraction means for each reception position at which the antenna received the radio waves. The determination means determines whether the wireless tag that transmitted the radio wave is inside a predetermined region based on the amount of change of phase stored in the storage medium.
