This paper presents a novel method of designing microstrip line multi-frequencies band filters by applying the SIR (stepped impedance resonators) technology. Utilizing the S-parameter and the ABCD parameters of a two-port network is for the analysis of short-circuited and open-circuited resonators with various combinations of series and shunt sequences. By controlling the impedance ratio of the resonators, both center frequencies of the two passbands then are determined. Moreover, a global synthesis approach is also discussed on miniaturization. A simplified architecture based on bent SIR offers the 50% area reduction of layout. Technology of matching circuit creates higher performance multiband filter. We adjust impedance and electrical length of transmission line (TL) to compensate multi-band and bending for matches and highly improve the insertion and reflection loss. Simulation and measurement are performed to validate our method and are pretty matched.
