Title:
MICROSTRIP LINE TYPE PRINTED CIRCUIT BOARD
Document Type and Number:
Japanese Patent JPH06120711
Kind Code:
A
Abstract:
PURPOSE: To obtain a microstrip line type printed circuit board for a high frequency signal in which the leakage of a signal or an interference between circuits due to the transmission of an unnecessary magnetoelectric wave in a printed circuit board dielectric can be prevented.
CONSTITUTION: A drill hole or a through-hole 10 is juxtaposed with a high density in which the transmission of the magnetoelectric wave of a desired band in the printed circuit board dielectric can be prevented. Then, it is possible to prevent the leakage of the signal due to the transmission of the unnecessary signal as the magnetoelectric wave from a pad 21 for an input signal to a pad 51 for an output signal in the printed circuit board dielectric.
