摘要：
A The resonance of the Modified dumbbell-shaped defected ground structure (MD-DGS) resonator on coplanar waveguide is investigated systematically based on the phase coherence of electromagnetic waves. Through the analysis of two presented interference modes, the resonant frequencies can be fully predicted, and the physical understanding behind these resonances is clearly revealed. The proposed analysis is verified by the simulation and measurement results of the MD-DGS resonator. Both the electric field distribution and the Poynting vector distribution of the MD-DOS resonator at the resonant frequencies further demonstrate the validity of the theoretical analysis.
