Summary: 
We propose a wide-band bandpass filter (BPF) with attenuation poles using coupled-lines and distributed tap-coupling resonators. In this case, we simulate the proposed BPF by using electromagnetic simulator. As a result, we have confirmed that wide-passband characteristics and improved out-of-band characteristics are obtained by coupled-lines and distributed tap-coupling resonators.
