A filter includes an input portion, a low-impedance transmission portion, a high-impedance transmission portion, and an output portion. The input portion receives electromagnetic signals. The high-impedance transmission portion is electrically connected to the input portion, and includes a first high-impedance transmission portion, a second high-impedance transmission portion, a third high-impedance transmission portion, a first connection portion, and a second connection portion. The low-impedance transmission portion is electrically connected to the second high-impedance transmission portion, and includes a pair of protrusion portions. The output portion is electrically connected to the third high-impedance transmission portion, for outputting the electromagnetic signals therefrom. The first connection portion electrically connects the first high-impedance transmission portion to the second high-impedance transmission portion. The second connection portion electrically connects the second high-impedance transmission portion to the third high-impedance transmission portion.
