METAL CASE, UNIT CELL FOR PREVENTING ELECTRO STATIC DISCHARGE AND FORMING METHOD THEREOF

摘要

A metal structure, a unit structure, and a method for forming the metal structure are provided to reduce a surface current on a metal structure of an electronic product by using an electromagnetic band gap. A metal structure for preventing electrostatic discharge includes an electromagnetic band gap(100), a metal structure(110), an opening part(120), and a unit structure(130). The opening part is formed a front surface of the metal structure. The electromagnetic band gap suppresses a current generated by the electrostatic discharge. The electromagnetic band gap is formed by an arrangement of the unit structure. The unit structure has a triangle or a rectangular shape. The electromagnetic band gap is formed by using a metal patch and a dielectric. The dielectric is formed between the electromagnetic band gap and a metal plate. The dielectric supports the electromagnetic band gap.
