Abstract: A defected ground structure with shielding effect is provided. The structure includes a dielectric layer, a defected metal layer, a grounded metal layer and at least a conductive mushroom-like structure. The defected metal layer has a line-shaped opening and is disposed in the dielectric layer. The conductive mushroom-like structure is disposed between the defected metal layer and the grounded metal layer and is arranged along an extending direction of the line-shaped opening periodically. The conductive mushroom-like structure includes a laterally extending member and a vertically extending member. The laterally extending member is parallel to the defected metal layer and a distance is maintained away from the defected metal layer. The projection area of the laterally extending member on the defected metal layer covers a length of the line-shaped opening corresponding to the laterally extending member. The vertically extending member connects the laterally extending member and the grounded metal layer.

Abstract: A method for reducing EM radiation comprises at least one first resonance line disposed on one of electric surfaces, which is disposed at a side of a transmission line structure on one of the electric surface. The resonance line crosses over a slot of another electric surface. The slot is etched on a corresponding electric surface. In addition, the transmission line structure crosses over the slot of the electric surface. Then, the first resonance line connects the electric surface having the slot with another electric surface. It can adjust at least one of a length, a width and a shape of the first resonance line, to make an input impedance seen from a crossed point between the transmission line structure and the slot approximately 0.

Abstract: Proposed is an apparatus for silencing electromagnetic noise, characterized by a plurality of centrally symmetrical ring-shaped through-via-hole crystalline units provided between a high voltage plane and a low voltage plane at a regular interval, thereby forming an omnidirectional noise suppression frequency band for reducing noise interference and electromagnetic radiation. In a first embodiment of the ring-shaped through-via-hole crystalline units, the through via holes are perpendicularly coupled between a metal plane and the low voltage plane. In a second embodiment of the ring-shaped through-via-hole crystalline units, the through via holes are perpendicularly coupled between two metal planes. Positioned at a regular interval, the through via holes enable provision of omnidirectional noise suppression frequency band, simplified design of a power plane, and reduction of production costs.
