Pinwheel Meander-Perforated Plane Structure for Mitigating Power/Ground Noise in System-in-Package

In this paper, a small electromagnetic bandgap structure that is suitable to be integrated into system-in-package is designed. The proposed structure, which is named as pinwheel perforated plane (PMPP), consists of meander line, mushroom-type patch, and the extended ground structure that is called a pinwheel. The proposed structure comprises three layers: top, middle, and ground. Moreover, the size of the proposed unit cell is 2.44 mm × 2.44 mm. The 3-D electromagnetic simulation results reveal that the cascaded 1 × 2 PMPP structure generates a stopband frequency of 3.35-28.17 GHz at a suppression depth of -40 dB. The power/ground noise suppression effect is confirmed by dispersion analysis from 3-D electromagnetic solver eigenmodes. Signal and power co-simulations are also performed to validate its integrity.
