Slow‐wave CPW resonator with defected ground structure (DGS) for filter applications [PDF]
Microwave and Optical Technology Letters, 2005 AbstractNovel slow‐wave CPW resonators with defected ground structures (DGSs) in a rectangularly spaced and open‐loop shapes are investigated. These structures have an extremely compact size. The simulations and experimental results verify that these structures provide a size reduction of about 54% as compared to a conventional CPW resonator.
