要約(英語): This paper describes the mechanism of radiated emission from a PCB (printed circuit board) with a slit. The multilayer PCB has a power plane and a ground plane, and they make up a parallel resonator. It is reported that when there is a slit at the power plane, the resonant frequencies are varied and the strength of radiated emission is also altered. However, the radiated emission from the PCB with a slit has not been cleared, although it is generally thought that the amount of the radiated emission will be increased. In this paper, the radiated emission from a PCB with a slit is measured and numerically analyzed using FDTD. It has been shown that the amount of radiated emission decrease at 1st mode when there is a slit. And its reason has been also cleared by investigating both amplitude and phase of the tangential electric field on the PCB with a slit.
