Novel reconfigurable multiband bandpass filter using defected ground structure on CPW technology

In this paper, a novel reconfigurable bandpass filter based on defected ground structures has been presented. The filter consists of two basic elements. The first is the inductively coupled resonator giving the bandpass filter response, and the second is the novel DGS cell allowing reconfigurability and miniaturization. Simulated and measured results are in good agreement. The flexibility of the design in the different cases has also been demonstrated.
