Abstract
A novel ϕ-shape defected ground structure (DGS) is proposed in this article.Low-pass filters are designed using the ϕ-shape DGS with H shape open stubs line. Single, two-cascaded and three-cascaded ϕ-shape DGS low-pass filters are designed, simulated, fabricated, and measured. The resonant characteristic of the two-cascaded ϕ-shape DGS low-pass filter shows its advantages of compact size, high selectivity, low insertion loss, and excellent passband performance. The frequency response of the three-cascaded ϕ-shape DGS low-pass filter presents the advantages of compact size, high selectivity, low insertion loss, better passband performance, and high outband suppression. The measured results show a good agreement with the simulated results. © 2011 Wiley Periodicals, Inc.
