Abstract:
1. A low-pass filter comprising: a high impedance part comprising a first transmission portion, a second transmission portion disposed parallel to the first transmission portion, and a third transmission portion electronically connectable between the first transmission portion and the second transmission portion and extending aslant relative to the first and second transmission portions; an input part electronically connected to the high impedance part for input of electromagnetic signals thereinto; an output part electronically connected to the high impedance part for output of electromagnetic signals therefrom; a first low impedance part electronically connected to one end of the high impedance part; and a second low impedance part electronically connected to the other end of the high impedance part; wherein the high impedance part is partly disposed between the first low impedance part and the second low impedance part; and the input part and the output part are asymmetrical to a resonator defined by the high impedance part, the first low impedance part, and the second low impedance part.
