Abstract
Abstract A radio frequency identification tag (14) includes a radio frequency identification tag circuit chip (12) coupled to an antenna (10) including a conductive pattern (22) printed onto a substrate (16). The substrate may form a portion of an article, a package, a package container, a ticket, a waybill, a label and/or an identification badge. The conductive pattern includes a first coupling region (28) and a second coupling region (30) arranged for coupling to the radio frequency identification tag circuit chip. The first coupling region and the second coupling region are precisely located and isolated from one another via an aperture (31) formed in the substrate.
