A systematic design method is proposed to achieve the optimal design of bandstop power delivery network (PDN) using resonant vias in a multilayered printed circuit board (PCB). With the proposed equivalent-circuit model, design equations, and design charts, the geometrical structure of a resonant via-type bandstop structure can be quickly designed according to the desired stopband bandwidth and isolation level. Wideband bandstop PDN designs using the resonant vias in standard four-layer PCB are fabricated and measured to demonstrate the effectiveness of proposed design method.
