PURPOSE: A communication module with a metal core printed circuit board is provided to reduce a noise figure of a communications module by preventing parasitic capacitance. CONSTITUTION: A communications module(100) of a multiple layers substrate comprises a plurality of board layers, a copper foil layer(120), and a pad part(140). A plurality of board layers comprises a circuit configuration for the signal processing. The copper foil layer comprises a copper cut pattern(160). The copper cut pattern corresponds to the external signal wiring. An external signal is supplied to the circuit configuration through the external signal wiring. The external signal wiring transfers the output signal of the circuit configuration to the outside. A pad part electrically interlinks the external signal wiring to the circuit configuration.
