PROBLEM TO BE SOLVED: To obtain an antenna system, capable of surely reading out the data of a radio type noncontact ID tag, independently of the size of a baggage by suspending a flexible antenna wiring an antenna conductor on an insulating sheet, so as to form a required antenna pattern like a curtain crossing a carrier line. SOLUTION: A sheet-like flexible antenna 6 is used for an antenna system 5. The antenna 6 wires a flexible antenna conductor 8 on a flexible insulating sheet 7, so as to form a required antenna pattern. Then antenna 6 is suspended by a supporter 9 like a curtain crossing a carrier line 2. Since the antenna 6 is deformed to a state lapping a baggage 1 passing through the antenna 6, a distance between the antenna 6 and a radio type noncontact ID tag 3 stuck to the baggage 1 is shortened, and data can be surely read out. |
