Abstract
A wireless tag reader/writer antenna according to an embodiment of this invention includes an antenna unit that incorporates a reader/writer antenna for transmitting and receiving electromagnetic waves to and from wireless tags; and a plurality of magnetic-wave shields that clamp the antenna unit and extend in a direction of radiating electromagnetic waves from the reader/writer antenna. The magnetic-wave shields are configured be provided to be detached or to slide. So configured, the magnetic-wave shields can effectively block electromagnetic waves that are detrimental to communication with the wireless tags.
