Abstract:
1. A printed circuit board comprising: a first dielectric layer having a first surface and an opposite second surface; a first conductive layer coupled to the first surface of the first dielectric layer; a second conductive layer coupled to the second surface of the first dielectric layer; and a localized distributive non-discrete capacitive element adjacent the first conductive layer, the localized distributive non-discrete capacitive element comprising: wherein the capacitive element is defined by a perimeter band that surrounds and approximately coincides with an outer perimeter for a device to be decoupled by the localized distributive non-discrete capacitive element, the perimeter band defining an interior open area, traversing the thickness of the printed circuit board, and an exterior area located opposite the interior open area, the interior open area devoid of any capacitive elements.
