摘要Abstract: The UWB filter at lower passband has good measured results, including a center frequency f0 of 4.35 GHz, low insertion loss of -1.9 + 0.4 dB, wide bandwidth of 3.5–5.2 GHz (FBW 39%). The UWB filter at higher passband also shows good measured results, including a center frequency f0 of 8.1 GHz, low insertion loss of -2 + 0.5 dB, wide bandwidth of 6.5–9.7 GHz (FBW = 40%). The measured upper stopband is significantly widened up to 20GHz with an attenuation level higher than 23 dB. The measured locations of transmission zeros appear at 2.6, 5.9 and 12.7 GHz .
