摘要
本文研究了利用电磁带隙结构(EBG)抑制印刷电路板上的平行板模式。我们考虑地面或动力面上的平面结构。两个单元几何形状用于在两个简单的测试板上创建4 x 4晶格，其中连接器端口表示过孔。这与没有这些结构的参考测试板相比较。测量结果表明，即使采用简单的布置，也可以非常有效地抑制平行板模态。
Electromagnetic bandgap structures for printed circuit board EMC
This paper investigates the suppression of parallel- plate modes on printed circuit boards via electromagnetic bandgap structures (EBG). We consider planar structures on ground or power planes. Two unit-cell geometries are used to create a 4 x 4 lattice on two simple test boards, where connector ports represent vias. This is compared to a reference test board without these structures. Measured results show that, even with a simple arrangement, it is possible to suppress parallel-plate modes very effectively.
