Abstract
An EBG (Electromagnetic Bandgap) structure includes a magnetic material portion at least in part. It is preferable to arrange the magnetic material portion close to or, if possible, in contact with a conductor forming the EBG structure, for example, at least a portion of a ground conductor, a conductor producing a capacitance, and/or a conductor producing an inductance, such as a via. Examples of the magnetic material portion include a ferrite plating film, a composite magnetic material layer including magnetic powder and resin binder, and the like.
