Patent attributes
A band-pass filter (10) for reducing harmonic electromagnetic signals includes an input line (100), an output line (120), at least one first resonator (140), and at least one second resonator (160). The input line inputs electromagnetic signals. The output line outputs electromagnetic signals. The first resonator includes a first grounded end (141), electronically connected to the input line, and a first open end (142). The second resonator is disposed parallel to the first resonator. The second resonator includes a second grounded end (161), electronically connected to the output line, and a second open end (162). The first grounded end is disposed in the same direction as the second grounded end, and the first open end is disposed in the same direction as the second open end.
