A harmonics suppression filter includes a main circuit, a first inner circuit, a first outer circuit, a first inner node and a first outer node. The first inner circuit, the first outer circuit and the main circuit are in the same layer of the base board. Meanwhile, the first inner circuit is located inside of the main circuit. There is an inner gap between the first inner circuit and the main circuit. The first outer circuit is located outside of the main circuit. There is an outer gap between the first outer circuit and the main circuit. The first inner node is located in the inner gap to couple the first inner circuit with the main circuit. The first outer node is located in the outer gap to couple the first outer circuit with the main circuit. |

1. A harmonics suppression filter located in a base board for suppressing harmonics, the harmonics suppression filter comprising:
a first signal port; a second signal port; a main circuit, located in a first layer of the base board, the main circuit comprising a first end coupled to the first signal port and a second end coupled to the second signal port; a first inner circuit, located in the first layer of the base board, and located inside of the main circuit, wherein the first inner circuit and the main circuit collectively define an inner gap; a first outer circuit, located in the first layer of the base board, and located outside of the main circuit, wherein the first outer circuit and the main circuit collectively define an outer gap; a first inner node, located in the inner gap and coupled with the main circuit and the first inner circuit; and a first outer node, located in the outer gap and coupled with the main circuit and the first outer circuit. |
