A Triangle-Shaped Band-pass Filter with Meander-Line Resonator and Complement Split-Ring Resonator (CSRR) Defected Ground Structure (DGS)

A band-pass filter is a wireless component that transmits frequencies within certain range and attenuates outside range. Band-pass (BPF) has been used as core for an Radio Frequency (RF) communication system. BPF generally designed based on transmission line resonators. Therefore, miniaturization of these components important. In this study, triangle-shaped with meander-line resonator complement split-ring (CSRR) defected ground structure (DGS) not have propose in study. Four different designs simulated. addition to comparing the CSRR DGS effect designs, it tried get better results added perturbation. The materials thicknesses filters kept constant. fabricated standard h 1 mm thick Rogers RO3003 substrate dielectric constant ɛr 3. It aimed obtain by making only geometric changes. Making changes reliable more than one band-with ranges intended. 5 GHz frequency Wi-Fi which also provided considerable 3.2 GHz. numerical compared found Compared sources, efficient achieved.
