Abstract

Abstract:

In allusion to the suppression of the simultaneous switching noise (SSN) within the power/ground planes of the printed circuit boards, a novel planar electromagnetic band-gap (EBG) structure is proposed. The novel design is based on using meander lines to increase the effective inductance of EBG patches, and the unit cell of the EBG power plane consists of one square patch with the slots and four meander line bridges. The design is validated numerically, and simulation results show that the -30dB suppression bandwidth ranges from 0.40GHz to 5.1GHz compared with the L-bridged EBG of the same parameters, that the lower cut-off frequency is decreased by 200MHz, and that the relative bandwidth is increased by about 16.2%. In addition to the advantage of the omnidirectional suppression of the SSN, the proposed EBG structure can be achieved by means of the standard PCB process.
