A constructal H shaped power distribution network for EBG structure power plane

In this paper, an H-shaped power distribution network is designed based on constructal theory for EBG structure in PCB power plane, to optimize the direct current performance. EBG structures provide noise suppression performance and the network provides currents. This network is composed of hierarchical metal paths, and the geometric parameters can be optimized according to constructal theory. The optimal performance consists of constructing the giving area in a sequence of building blocks from the smallest size toward larger sizes hierarchically. In the meantime, a PCB power plane is developed based on the 2^nd order H-shaped constructal network which illustrates that EBG power plane with H-shaped network has multifunctions of low voltage drop, current equidistribution and effective noise isolation.
