Abstract
Ultra-wideband (UWB) high-speed planar circuits suffer from power/ground noise due to voltage fluctuations, ground bounce, return-path discontinuities, and plane resonances, leading to electromagnetic interference (EMI) and signal integrity (SI) degradation. Suppressing simultaneous switching noise (SSN) is crucial for ensuring stable power delivery in high-speed printed circuit boards (PCBs). This study presents a metamaterial-inspired electromagnetic bandgap (EBG) structure aimed at mitigating broadband noise. The stub-loaded cross-shaped resonator (SLCSR) provides a peak noise suppression of −37 dB. Using cascaded and long-bridge SLCSR-based EBG designs further increases suppression to −47 dB and −52 dB, respectively. When vias are incorporated, the structure achieves up to −55 dB suppression across the ultra-wideband (UWB) spectrum. Experimental results from fabricated prototypes closely match the simulations, demonstrating the effectiveness of the proposed design.
