Abstract The defected ground structure(DGS)and its application are introduced.Based
on analysis of simultaneous switch noise(SSN)and suppression methods for it,a novel
dumb-bell shape DGS in application to medical electronics device PCB is designed.The
results of the experiments and actual application show that the DGS design is effective
