摘要: An ultra-wide band (UWB) band-pass filter (BPF) based on signal interference technique is presented in this letter. The connected parallel short-ended interdigital coupled lines and a transmission line. has fractional bandwidth of 108% two zeros at both sides pass-band, which turns into good pass-band selectivity. achieves small size 10.55 mm × 8.9 (0.33 λg 0.27 λg, where the guided wavelength 6.85GHz). For verification, sample simulated, fabricated measured. Good agreement found between simulation measurement.
