摘要：
In this paper, a lamination of a magnetic sheet and a copper sheet is proposed to obtain wideband shielding effect from kHz to MHz bands. The requirement of the laminated magnetic sheet was discussed. A cap type shield case applying the laminated sheet 53 mu m thick was fabricated and its shielding effect was measured. The higher shielding effect was obtained using the proposed sheet in the frequency range from 0.2 MHz to 6 MHz compared with that of the copper case of 70 mu m, and it was improved by 15 dB at 0.2 MHz.
