Abstract :
A novel structure for noise isolation in ultra-wideband applications is designed, fabricated and measured. The structure is a hybrid alternating impedance electromagnetic bandgap (AI-EBG) structure and shows excellent noise isolation over 10 GHz. This cost-effective hybrid AI-EBG structure shows better noise isolation and suppression capability (over -80 dB isolation on average in an ultra-wide stopband range) than any reported EBG-based structures.
