Basic left hand mode transmission line (LH mode TL) characteristics made on PCB is an important future issue for the application of the EMC field. In this paper, possibility of a LH mode TL characteristic made by a folded-stepped impedance resonator (F-SIR) type is investigated experimentally and numerically. The experimental and calculated from FEM and equivalent circuit results indicate that some backward propagation characteristic and negative group delay can be established by F-SIR structure.
