Abstract
An EMI noise reduction board using an electromagnetic bandgap structure is disclosed. In the EMI noise reduction board according to an embodiment of the present invention, an electromagnetic bandgap structure having band stop frequency properties can be inserted into an inner portion of the board so as to shield an EMI noise, in which the portion corresponds to an edge of the board and in which the EMI noise is conducted from the inside to the edge of the board and radiates to the outside of the board.
