Abstract

A novel microstrip low‐pass filter utilizing defected ground structure (DGS) units is presented in this article. A DGS unit is simulated with different physical dimensions in order to show variation of attenuation pole and cut‐off frequency. Next, a low‐pass filter using proposed DGS unit is designed. A method for determining dimensions of microstrip structure and DGS units is proposed. Influence of dimensions of the microstrip structure on filter characteristics is investigated and simulated. Filters of various orders are simulated as well. Selected filter is simulated and experimentally verified. © 2007 Wiley Periodicals, Inc.

## Abstract A novel compact microstrip low‐pass filter (LPF) is proposed in this article. The proposed LPF is composed of semicircle‐defected ground structures (S‐DGS) and semicircle stepped‐impedance shunt stubs (S‐SISS). An equivalent lumped L‐C circuit model is also presented. With the S‐DGS and
