Problems solved by technology

[0002] The electromagnetic energy gap structure can be used to suppress the propagation of electromagnetic wave noise, but the traditional electromagnetic energy gap structure is mostly a planar structure, which requires a large circuit area
[0003] When the circuit space inside the electronic device is not enough, it is difficult to set a sufficient number of electromagnetic energy gap structural units, which will reduce the ability to suppress the propagation of electromagnetic wave noise

Abstract

The present invention proposes a three-dimensional electromagnetic bandgap circuit, comprising: a dielectric layer having a first surface and an opposite second surface; a helical element located on the first surface; a first surrounding element located on the first surface, and wraps around the helical element but does not touch the helical element; the planar element is on the second surface and includes a notch; the second wrapping element is on the second surface and wraps around the planar element but does not contact the planar element, wherein the second surrounding element also includes a protrusion extending toward the gap; the first guide hole penetrates the dielectric layer, the spiral element, and the protrusion; the second guide hole penetrates the dielectric layer, The planar element, and the first surrounding element; and the third guide hole, passing through the dielectric layer, the planar element, and the first surrounding element.

Description

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