Abstract :
Proposed is a design for a partial uniplanar compact electromagnetic bandgap (UC-EBG) structure, in conjunction with a high-impedance surface (HIS), to suppress simultaneous switching noise (SSN) over the wide frequency range 0.38-15.494-GHz. Different from the conventional methods, which use an EBG plane, the proposed structure uses only two UC-EBGs at the excitation and receiving ports to suppress SSN. This technique can be applied to sensitive circuits to maintain their power integrity. The other region maintains good signal integrity when a signal return path is referenced to an EBG plane.
