무선충전기의 무선충전패드 상에 휴대단말기의 위치 고정용 자석이 내장되어 있는 경우에 적합하고, 상기 무선충전패드 상에서 휴대단말기의 배터리 무선충전시 자석에서 발생되는 자력에 의해 무선충전효율이 저하되는 것을 방지 및 휴대단말기의 슬림화를 위한 적용두께를 만족시킬 수 있도록 한 것으로서;It is suitable when a magnet for fixing the position of the mobile terminal is embedded on the wireless charging pad of the wireless charger. It is to satisfy the application thickness for the prevention and slimming of the mobile terminal;

베이스시트 상에 무선충전용 안테나코일과 무선인식용 안테나코일이 내외측 방향에 위치하여 각각 구별되게 배치되며, 상기 무선충전용 안테나코일과 무선인식용 안테나코일이 베이스시트의 양면에 대칭구조로 대응 형성되는 안테나시트;On the base sheet, the antenna coil for wireless charging and the antenna coil for wireless recognition are arranged in the inner and outer directions, respectively, and the antenna coil for wireless charging and the antenna for wireless recognition are symmetrically arranged on both sides of the base sheet. An antenna sheet formed;

상기 안테나시트의 배면에 위치하여 일체 결합되며, 일면 중심부에 요(凹)부와 철(凸)부의 반복 형성에 의한 요철구조로 형성되고 무선충전용 안테나코일과의 매칭 결합을 통해 무선충전시 전자석 효과를 유도함과 더불어 무선충전패드의 자석에서 발생되는 자력을 분산 및 약화시키기 위한 충전효율증대부를 갖는 자성물질에 의한 전자파흡수시트;It is located on the back of the antenna sheet is integrally coupled, and formed in the concave-convex structure by the repeated formation of the concave portion and the iron portion in the center of one surface and the electromagnet during wireless charging through matching coupling with the antenna coil for wireless charging Electromagnetic wave absorption sheet by a magnetic material having an increase in charging efficiency for inducing the effect and to disperse and weaken the magnetic force generated in the magnet of the wireless charging pad;
