The characteristics of microstrip lines supported by photonic bandgap (PBG) structures are studied. Defected ground planes have been adopted to build up novel microstrip lines. Numerical simulation based on FDTD method and experiments have been carried out?The cases of rectangular holes and a filter constructed by cascaded PBG lines have been studied. Frequency transmission curves are given, and the existence of a bandgap is proved.
