摘要: A novel ultra-wideband (UWB) bandpass filter (BPF) with triple notched bands is presented in this paper. The basic UWB BPF realized by a Y-shaped multi-mode resonator. In order to reject the interfered signals, dual-mode stepped impedance resonator embedded introduce dual at 5.85/8.13 GHz. Due asymmetrical coupling structure, another band centered 7.12 GHz implemented as well. Analysis of has been done classical even- and odd-mode methods. For verification, two sample filters have simulated, fabricated, measured. Good agreement found between simulations measurements. implementation area proposed 14.7 × 10.1 mm2.
