TAG ANTENNA

摘要

PURPOSE: A tag antenna is provided to apply maximum power to a tag chip by forming a slit on a metal layer. CONSTITUTION: A slit(102) is formed on a metal layer(100) and has the length of λ/2 and a monopole or meander line shape. An insulation layer(110) is printed on the upper surface of the metal layer. A closed loop antenna pattern(130) is printed on the upper surface of the insulation layer. The closed loop antenna has a circular, square, or meander line shape. A tag chip(120) is attached to the upper side of the insulation layer.
