Abstract

The invention provides a three-dimensional electromagnetic energy gap circuit. The three-dimensional electromagnetic energy gap circuit comprises: a dielectric layer having a first surface and a second surface opposite to the first surface; a helical element located on the first surface; a first surrounding element which is located on the first surface, surrounds the spiral element and does not make contact with the spiral element; a planar element located on the second surface and comprising a notch; a second surrounding element which is located on the second surface, surrounds the peripheryof the planar element, does not make contact with the planar element and further comprises a protruding part extending towards the notch; a first guide hole penetrating the dielectric layer, the spiral element and the protruding part; a second guide hole penetrating the dielectric layer, the planar element and the first surrounding element; and a third guide hole penetrating the dielectric layer,the planar element, and the first surrounding element.

Description

Technical field [0001] The present invention relates to an electromagnetic bandgap (electromagnetic bandgap) structure, in particular to a three-dimensional electromagnetic bandgap circuit (3D electromagnetic bandgap circuit). Background technique [0002] The electromagnetic energy gap structure can be used to suppress the propagation of electromagnetic wave noise, but most of the traditional electromagnetic energy gap structure is a planar structure, which requires more circuit area. [0003] When the circuit space inside the electronic device is insufficient, it is difficult to provide a sufficient number of electromagnetic energy gap structure units, which will reduce the ability to suppress the propagation of electromagnetic wave noise. Summary of the invention [0004] In view of this, how to effectively reduce the circuit area occupied by the electromagnetic energy gap structure is a problem to be solved. [0005] This specification provides an embodiment of a three-dimensiona...
