摘　　要：基于对偶电路定理和等效电路模型,提出了哑铃型缺陷地面结构（DGS）的快速综合和分析方法,给出了详细的综合和分析步骤。综合设计和分析了谐振于5GHz的哑铃型DGS,综合的结构参数误差小于5%,频偏误差只有2.8%。理论和测试结果显示了该方法的有效性,可被广泛应用于DGS的设计当中。Based on the duality circuit theorem and equivalent circuit model, the fast synthesis and analysis method of dumbbell-shaped defected ground structure is proposed, and the detailed synthetical and analytical procedures are given. The DB-DGS at the resonance frequency 5GHz is synthesized and analyzed,the structure parameters errors are less than 5%, and the resonant frequency is only 2.8% of deviation. Simulation and measurement results proved the validity of the proposed methods and the methods can be widely used in the design of defected ground structure.
