一种具有新颖电磁带隙结构的印刷电路板电源平面
Power plan of the printed circuit board with novel electromagnetic band-gap structures
摘要
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 -30 dB suppression bandwidth ranges from 0. 40 GHz to 5.1 GHz compared with the L-bridged EBG of the same parameters, that the lower cut-off frequency is decreased by 200 MHz, 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.关键词
