摘要: 该文设计了一种新型一维周期地面缺陷(Defected Ground Structure, DGS)单元结构，该DGS单元结构提高了等效电感。增加的等效电感可以容易控制DGS平面电路的截止频率特性。设计的周期DGS单元结构有非常好的截止和带阻特性。为了显示改进的等效电感，该文设计了3个周期相同而单元尺寸不同的DGS电路。DGS电路的测试结果显示截止和带阻的中心频率特性由该DGS单元结构的物理尺寸决定。

Abstract: A new onedimensional periodic defected ground unit structure is proposed in order to improve the effective inductance. Increasing the effective inductance makes it easy to control the cutoff frequency characteristics of the DGS planar circuits. The proposed period Defected Ground Structure (DGS) provides the excellent cutoff and stopband characteristics. In order to show the improved effective inductance, three DGS circuits are fabricated with identical period and different dimensions. Measurements on the fabricated DGS circuits show that the cutoff and stopband center frequency characteristics depend on the physical dimension of the proposed unit lattice. -
