A new pinwheel meander-perforated plane structure for noise suppression in system-on-package

Abstract

As the market of wearable and internet of things (IoT) expands, there is a strong demand of shrinking the size of System-on-Package (SoP). In this paper, we propose a new electromagnetic bandgap structure (EBG) to mitigate the noise coupling within SoPs. EBGs have been widely used in printed circuit boards (PCB). Thus, the EBG size reduction is critical for integrating it in the package. The proposed structure has a unique noise suppressing pinwheel meander perforated plane structure (PMPP) that can be used in small size package. Critical problem of EBG's size reduction is shifting the suppression frequency to higher. Therefore, we propose to combine the EBG structure, meander-line, and pinwheel shaped patch to reduce size of EBG unit cell from 12.2mm×12.2mm to 2.44mm×2.44mm while maintaining the suppression frequency and bandwidth. The stopband bandwidth of proposed structure is 3.58~12.83GHz.

Prediction of Meander Delay System Parameters for Internet-of-Things Devices Using Pareto-Optimal Artificial Neural Network and Multiple Linear Regression

“…Meander structures are used not only in the antennas, but in all microwave devices for shrinking the size of system on package (SoP). [13] have proposed a unique noise suppressing pinwheel meander perforated plane structure in order to mitigate the noise coupling within SoPs. Meander structures are also used to change the radiation pattern of the antenna array [14], to shift the electrical signals in time in order to create a positive feedback in oscillators [15] or to delay and synchronize signals from different sources [16].…”
