## Abstract In this letter, a novel bandβnotched ultraβwideband (UWB) bandpass filter (BPF) is investigated. A structure of complementary two turns spiral resonator (CSR2) is proposed to improve notch performance of the UWB BPF. The single CSR2 unit cell has a size of 0.08Ξ»~g~ Γ 0.08Ξ»~g~(what is Ξ»~
