Abstract
A wireless tag communication device includes an antenna configured to transmit a carrier wave and receive a response wave output from a wireless tag with respect to the carrier wave and to specify a position of the wireless tag to be searched based on a radio wave intensity of the response wave received by the antenna. The device includes: a radio wave controller configured to switch the carrier wave between a first and second carrier wave to be transmitted in a first and second polarization direction respectively; and a comparator configured to compare a first and second radio wave intensity of a first and second response wave respectively output from the wireless tag with respect to the first and second carrier waves respectively, and the radio wave controller switches the carrier wave between the first carrier wave and the second carrier wave based on a comparison result of the comparator.
