提出了一种新型的l桥频率选择面（FSS）电源/地平面，具有超宽带抑制600 mhz至4.6 GHz同时开关噪声的能力。FSS功率平面上的l型桥设计不仅拓宽了阻带带宽，而且增加了相邻FSS单元之间的相互耦合，使单元之间的间隙显著减小。研究发现，对于带孔FSS功率平面的信号，小间隙设计可以缓解信号质量的下降。实验和数值验证了该结构在保持良好信号完整性的同时具有良好的SSN抑制性能。很好地达成了一致。
A novel L-bridged frequency selective surface (FSS) power/ground planes is proposed with super-broadband rejection for simultaneous switch noise (SSN) from 600 Mz to 4.6 GHz. The L-shaped bridge design on the FSS power plane not only broadens the stop-band bandwidth, but also increases the mutual coupling between the adjacent FSS cells with allowing the significant decrease of the gap between the cells. It is found the small gap design can ease the degradation of the signal quality for the signal referring to the perforated FSS power plane. The excellent SSN suppression performance with keeping reasonably good signal integrity for the proposed structure is validated both experimentally and numerically. Good agreement is seen.
