NONCONTACT TAG ANTENNA MOUNTABLE ON METALLIC SURFACE

摘要

PURPOSE: A contactless tag antenna for attachment to a metallic surface is provided to increase sensing distance in comparison with general label tag and a metal tag by high gain. CONSTITUTION: A contactless tag antenna has meandered folded-dipole structure. The contactless tag antenna comprises a first conductive trace part(10), a second conductive trace part(20), a T-shaped matching part(30), and a loop part(40). The first conductive trace part is formed symmetrically to the second conductive trace part based on the T-shaped matching part. One end of the first conductive trace part is connected to the T-shaped matching part. The other end of the first conductive trace part is connected to the second conductive trace part.
