Abstract:
1. A multilayer printed circuit board, comprising: a power source surface to provide power to a plurality of electrical components; a ground surface having a reference voltage; a strip line formed to pass completely through the power source surface and/or the ground surface to transmit signals between at least two of the plurality of electrical components; an antenna disposed in proximity to a sectional region of the power source surface and the ground surface; and an electromagnetic wave reduction member separate from the power source surface provided between the power source surface and the ground surface in proximity to the antenna to reduce an electromagnetic wave generated from the strip line, wherein the electromagnetic wave reduction member includes a capacitor and a resistor arranged in series, and an interplane ground surface disposed between the capacitor and the resistor, the interplane ground surface serving to connect between the capacitor and the resistor to reduce the electromagnetic wave being generated from the strip line.
