Emi noise shield board including electromagnetic bandgap structure

Abstract

The present invention provides an EMI noise shield board in which an EBG structure is inserted. The EMI noise shield board in accordance with an embodiment of the present invention can include: a first board portion, an electronic part being mounted on an upper surface of the first board portion, a circuit for transferring a signal and power to the electronic part being in the first board portion; and a second board portion located on a lower surface of the first board portion, an electromagnetic bandgap structure being inserted into the second board portion, the electromagnetic bandgap structure having a band stop frequency property in such a way that an EMI noise transferred from the first board portion can be shielded from being radiated to the outside of a board.
