Abstract
Abstract
A simple and successful design for a microstrip stepped-impedance resonator (SIR) bandpass filter (BPF) based on inductive coupling is presented. It is well known that SIRs are used to shift or suppress the higher order frequencies. In order to achieve compact circuit size, a perceptual stepped-impedance resonator is utilized. Based on theoretical analysis, this resonator can shift the spurious frequency to 3.8f0. The experimental results show good agreement with theory and simulations.
