| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Electromagnetic bandgap (EBG) formed by a periodic structure (EBG structure) has been studied for reducing power-bus noise of printed circuit boards. The EBG structure obtains a large amount of noise suppression and is available for separating simultaneous switching noise generated in digital circuits and small rf signal in analog circuits on mixed-signal boards. Many kinds of EBG structures have been so far proposed and can be roughly classified into two types with and without vias. We have focused on Planar EBG structures without vias because they consist of only two layers and cost-effective due to no vias. In contrast, open-stub EBG structure, which is one of EBG structures with vias, is easy to miniaturize its cell size independently of suppression frequency. We considered that the open-stub EBG structure was specialized for the EBG structures with vias. In this report, however, a planer EBG structure with open stub is proposed by inventing a new structure. The effect of power-bus noise reduction is examined by full-wave simulation and validated in the 2.4 GHz band. |
