摘要
For a microstrip line with an asymmetric spiral-shaped defected ground structure (DGS), an equivalent circuit model is presented. From the lumped-element circuit model describing the asymmetric properties in circuit elements as well as in their magnetic coupling to the host line, the two rejection frequencies are derived. The equivalent circuit model provides physical insight into the dual-frequency operation of the asymmetric spiral-shaped DGS.
