In this letter, we propose a vertical inductive bridge electromagnetic bandgap (VIB-EBG) structure for size reduction of a unit cell and the wideband suppression of simultaneous switching noise (SSN) in a multi-layer package. With the proposed vertical inductive bridge, the inductance of an EBG unit cell is effectivel increased within a compact unit cell size. Compared to the previous planar bridge EBG structure, the proposed VIB-EBG structure achieves an 86% enhancement of the fractional stopband bandwidth and a 58% reduction in unit cell size. The starting frequency of the first bandgap (f(L)) is significantly reduced from 4.0 to 1.7 GHz. Wideband SSN suppression with a size reduction was successfully verified by HFSS simulations and measurements.
