Abstract: PURPOSE: An electromagnetic bandgap pattern is provided to enable a security code using electromagnetic field characteristics and to produce security products comprising EBG pattern. CONSTITUTION: An EBG(Electromagnetic Band Gap) pattern(100) includes a nonconductor film(110) and a plurality of EBG pattern units(100a~100c). The EBG pattern unit is formed on the film by conductive substances. In the EBG pattern units, a plurality of closed loop pattern and a plurality of opened loop patterns are regularly arranged. The EBG pattern unit is consecutively arranged on the film in a band form.
