Abstract (en)
[origin: WO0004519A1] A tag for use in an Electronic Article Surveillance system is disclosed. Such tags are typically provided internally with a transponder circuit comprised of first and second resonant circuits, each provided with inductive components between which there is at least some mutual magnetic coupling and/or electrical coupling. The tag according to the invention is identified by the angle subtended between the axes of the inductive components of the first and second resonant circuits, as it has been found by the applicants that this angle substantially affects the "pick rate" of a tag, i.e. the number of times a particular tag is actually detected by a system compared to the number of times the tag passes through the system. The longitudinal axes of said first and second inductance coils ideally subtend an angle of theta DEG , where 90 DEG < theta DEG < 180 DEG , theta DEG < > 90 DEG , 180 DEG .
