摘要: Microstrip based ultra-wideband (UWB) bandpass filter (BPF) with controllable triple notches and simultaneously extended upper stopband is proposed. Initially an UWB on back-to-back microstrip to co-planar waveguide (CPW) technology constructed. Band notch property integrated into the by implementing complementary split ring resonators (CSRR) defected ground structures (DGS) in of this filter. Double equilateral-U (DEU) DGS etched under input output feeding lines suppress spurious harmonics extend stopband. An approximate lumped equivalent circuit model proposed structure presented. Full wave simulations are good agreement measured results.
