Abstract :
In this paper, a dual-mode square ring bandpass filters with defected-ground structures (DGS) is proposed. By employing the DGS, the coupling is enhanced and the insertion loss is reduced effectively. The harmonic suppression is achieved by loading DGS structures under the input/output lines. Good agreement between the experimental and simulation results is observed.
