Abstract

In this letter, a power plane with wideband simultaneous switching noise (SSN) suppression using a novel multi-via electromagnetic bandgap (EBG) structure is proposed. The -40dB stopband of the proposed EBG structure is about two to six times wider than the one-via structure, and the relative bandwidth is increased by about two times. It is implemented by only adding some vias between patches and the reference plane without changing any other geometrical parameters from one-via EBG structures. The excellent SSN suppression performance was verified by simulations and measurements
