A MULTILAYER PRINTED CIRCUIT BOARD

摘要

A multilayer PCB(Printed Circuit Board) is provided to prevent deterioration of receiving sensitivity of a broadcast receiving antenna by reducing electromagnetic waves around the broadcast receiving antenna adjacent to a cross section thereof. A multilayer PCB(10) includes a power plane(12), a ground plane(13), a strip line(14), an antenna(11), and an electromagnetic wave reducing member. The power plane supplies power to components. The ground plane has reference voltage. The strip line passes between the power plane and the ground plane and receives signals between the components. The antenna is installed adjacently to cross sections of the power plane and the ground plane. The electromagnetic wave reducing member is arranged between the power plane and the ground plane around the antenna to reduce electromagnetic waves generated from the strip line. The electromagnetic wave reducing member is a capacitor(17) and a resistor(18).
