AbstractIn this paper, a kind of coplanar waveguide (CPW)-fed series stub structure is proposed and its application in wideband bandpass filters (BPFs) is developed based on the coplanar strip (CPS) dual stubs. Compared with its conventional CPS dual-series-stub counterparts, the proposed one excited by even-mode CPW lines possesses enhanced immunity against unexpected resonance of the CPS-based series stubs. By virtue of this attractive performance, desired resonance can be well realized with predicted in-band characteristics. Subsequently, the application in its constituted wideband BPFs is investigated with synthesis design method. In final, one third-order and one fifth-order BPFs are designed, fabricated, and measured to verify the proposed structure. Measured results are found in reasonably good agreement with the synthesized and the simulated ones.
