Abstract:
A low-pass filter (10) includes an input portion (100) for input of an electromagnetic signal, an output portion (120) for output of the electromagnetic signal, a high impedance transmission portion (140) electrically connecting the input portion and the output portion, a pair of low impedance transmission portions (160, 180) arranged on either side of the high impedance transmission portion, and a capacitor. One of the low impedance transmission portions electrically connects the input portion and one end portion of the high impedance transmission portion. The other low impedance transmission portion electrically connects the output portion and the other end portion of the high impedance transmission portion. One end of the capacitor is electrically connected to the high impedance transmission portion. The high impedance transmission portion is symmetrical about the capacitor.
