<P>PROBLEM TO BE SOLVED: To provide an antenna for a reader/writer that not only eliminates the need for changing a layout on a working table but also reads IC tag data without lifting baggage. <P>SOLUTION: An antenna 30 for RFID is constituted by the steps of disposing a concave portion 32 in the center of a ground plate 31, mounting a radiating element 35 in the center of the interior of the concave portion 32, and disposing a cover 41 on an upper portion thereof. The antenna for RFID 30 is mounted on a lower side of the working tabletop to be connected to a RFID reader/writer through a power supply cable. The baggage disposed on the working table are sorted by allowing them to be slid on the working table and by allowing IC tags attached to the baggage to be passed over the antenna for RFID 30. At this moment, the IC tag data is read by the reader/writer for RFID through the antenna for RFID 30. <P>COPYRIGHT: (C)2009,JPO&INPIT |
