Title:
WIRELESS ANTENNA INCLUDING ELECTROMAGNETIC WAVE ABSORPTION SHEET FOR BOTH RADIO FREQUENCY IDENTIFICATION AND WIRELESS CHARGING AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2013/180367
Kind Code:
A1
Abstract:
The present invention relates to a wireless antenna including an electromagnetic wave absorption sheet for both radio frequency identification and wireless charging and a manufacturing method therefor, and the wireless antenna is very useful when a location-fixing magnet of a portable terminal is embedded in a wireless charging pad of a wireless charger provided for the wireless charging of the portable terminal and, particularly, increases radio waves of a wireless charging frequency due to an electromagnetic effect by using the shape of an electromagnetic structure of a wireless charging antenna during wireless charging, prevents the deterioration of wireless charging efficiency of a battery in the portable terminal by inducing the dispersion and attenuation of a magnetic force of a magnet embedded in the wireless charging pad by using an uneven structure on an electromagnetic wave absorption sheet, and satisfies and improves the wireless charging efficiency required by the portable terminal market while satisfying the application thickness of a wireless antenna mounted in a slim portable terminal such as a smart phone.
