ABSTRACT:
A low-pass filter (100) for reducing harmonic electromagnetic signals includes an input line (120), an output line (140), a transmission line (160), a first coupling line (180), and a second coupling line (190). The input line is used for input of electromagnetic signals. The output line is used for output of electromagnetic signals. The transmission line is electronically connected to the input line and the output line for capturing and transmitting electromagnetic signals. The first coupling line includes a first open end (184), and a first feed-in end (182) electronically connected to the transmission line. The second coupling line includes a second open end (194), and a second feed-in end (192) electronically connected to the second end. The first feed-in end is located opposite to the second feed-in end. The transmission line, the first coupling line, and the second coupling line collectively form a substantially G shape.
