<p>The present invention relates to an antistatic bag comprising a metal packaging for preventing static electricity. The antistatic bag has a small loop tag comprising a reactance component caused by a self-loop at one edge thereof, and a slit having a 90° rotated square bracket shape ("ㄷ") is formed between the surface of the metal packaging and the tag so that the self-loop is electromagnetically connected to a metallic surface whereby the antistatic bag operates as a virtual dipole antenna. The sealed antistatic bag according to the present invention operates as a virtual dipole antenna component and induced energy is incorporated to the small loop tag, thereby establishing a wireless resonance connection so that the antistatic bag with a small strap tag attached thereto can exchange information according to a communication protocol with an RFID reader and can be identified. Accordingly, the present invention enables RFID logistics for each individual article stored in the sealed antistatic bag, and especially has excellent effects of improving a logistics service system and reducing logistics costs on the basis of quick and accurate management for each individual article.</p> |
