The analysis of one dimensional microstrip photonic bandgap filters by using the network theory

Changhong Liang

Abstract

The Network Theory is employed to analyze a type of 1D 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 Microstrip filter structure will have Stop-Band properties only if the characteristic impedance regularly varies along the length of the cell.
