摘　　要：为了有效分析一类一维微光子带隙(PBG)滤波器的电磁特性,应用微波网络理论对PBG单元阻抗变化范围、周期个数对PBG滤波器的传输特性的影响进行了分析.分析表明,只要PBG结构单元中特性阻抗按一定规律变化,其整体结构均会呈现带隙特性.The Network Theory is employed to analyze a type of 1 D microstrip PBG filter structure, and a detailed analysis is made to study the influence of the variation of characteristic impedance and the periodic number on the transmission characters. Finally it is concluded that the Micro.strip filter structure will have StopBand properties only if the characteristic impedance regularly varies along the length of the cell.
