Abstract :
In this paper, the mechanism of power noise suppression is investigated. It is shown that periodic structure results in stopband characteristic. Then a simple and easy-design periodic slotted electromagnetic bandgap structure with wideband power noise suppression is proposed based on the basic mechanism. Both simulated and measured results are given which are consistent each other.
