Abstract
A low-pass filter (10) includes an input portion (100) inputting an electromagnetic signal, an output portion (120) outputting the electromagnetic signal, a high impedance transmission portion (140) electrically connected to the input portion and the output portion to transmit the electromagnetic signal therebetween, a first low impedance transmission portion (160) electrically connected to the input portion and an end of the high impedance transmission portion, and a second low impedance transmission portion (180) electrically connected to the output portion and another end of the high impedance transmission portion. The two low impedance transmission portions are arranged beside the high impedance transmission portion, and each of the low impedance transmission portions is triangular.
