Abstract
The present invention relates to an electromagnetic wave shielding sheet for an antenna, to a method for manufacturing same, to an antenna comprising same, and to a battery pack for a portable terminal having said antenna. The method for manufacturing the electromagnetic wave shielding sheet for the antenna may reduce a frequency variation, provide a heat-dissipating function, and prevent peel-off. The method comprises: a step of preparing a ferrite sheet; and step of placing a heat-dissipating layer on one side of the ferrite sheet. The present invention has advantages in that the adhesive forces of the ferrite sheet and the heat-dissipating layer are excellent and the heat-dissipating effects are excellent, the electromagnetic wave shielding sheet can be applied to various antenna products, and the frequency variation can be reduced when the antenna having the electromagnetic wave shielding sheet is mounted on the battery pack.
