Abstract

This paper presents a novel reconfigurable DGS cell on CPW. The structure consists of two independent ring resonators. A diode is used to connect and/or disconnect the second resonator, switching the structure from single band to multi-band resonance circuit. An equivalent circuit has been extracted from the simulated results representing the DGS in both states of the diode. EM simulation, equivalent circuit model and measured results show good agreement. Finally, design rules and considerations have been illustrated.
