Abstract :
This research proposed a novel miniaturized coupled filters at 5.35GHz for WLAN application in duroid-6010 laminate substrate with four layers of metal. In order to reduce length of resonators, the stepped impedance resonator (SIR) theorem have been used. In addition, the coupled filter is designed in multilayer structure by using aperture-coupled. The area of filter in this research is 1mm×3.6mm and the result of measurement is consistent to simulation.
