Modified pinwheel meander-line perforated plane structure for system-in-package

Conventionally, EBG structures are used in the printed circuit boards (PCBs) level [1]. We proposed the Pinwheel Meander-line Perforated Plane (PMPP) structure as the solution [2]. In this paper, we modify the PMPP to reduce the area and electromagnetic emission (EMI). By reducing the thickness of dielectric layers and plane from 30μm to 10μm, we reduce the number of meander-line curves from 5 to 1, and the number of unit cells from 3 to 2. We confirm the electromagnetic compatibility (EMC) property through simulation, using 3D electromagnetic (EM) solver. The stopband frequency range of this proposed structure is 3.53~22.69GHz, which is wider than 3.58~12.83GHz, the stopband of the previous PMPP.
