Defected Ground Structures have multiple applications in the microwave domain, e.g., in the design of couplers, antennas, filters and filtennas. An accurate wide-band equivalent circuit model is proposed for Defected Ground Structures in this paper. This wide-band model can be used to model multiple resonances of a Defected Ground Structure with a single slot. Validation through measurements verifies the accuracy of the proposed model.
