A compact meander microstrip lines with 2D defected ground structures (DGS) and a microstrip line with a defected ground array (DGA) are proposed in this article. Their excellent bandgap characteristics are verified through simulation and measurements. Furthermore, the loss and slow-wave characteris

## Abstract The one‐dimensional (1D) defected ground structure (DGS) is used to control the cut‐off frequency characteristic. In this paper three non‐periodic filters are built, in order to show the versatility of DGS. Five unit cells of different shape with the same attenuation pole frequency were
