Abstract(in English) | Small size Note-type PC becomes a major Product in PC products today. Bacause of its size and thickness, the Battery-pack of Note-type PC is usually a columnar shape and located on the back of the Note-type PC. In the battery-pack, wirings to positive and negative poles are branched at the center of the buttery, then they form a strong radiation source as a dipole antenna. As a countermeasure against that radiation mechanism, a means of connecting each electrode to ground at a high frequency was provided. The effect was over 15dB for reducing radiated noise. |
