Abstract
An electromagnetic bandgap (EBG) pattern structure includes a nonconductive substrate and a pattern assembly formed on the substrate. The EBG pattern structure also includes regularly arranged closed-loop patterns and open-loop patterns, both of which are made of a conductive material. The EBG pattern structure can be used to manufacture new security products by applying its frequency characteristics to securities or IDs and variously used in security technologies for preventing forgery and alteration because various security codes can be created by adjusting the variables of its EBG pattern.
