ANTENNA DEVICE EMBEDDED WITH AN ANTENNA FOR NEAR FIELD COMMUNICATION AND A COIL FOR TRANSMITTING WIRELESS CHARGING POWER, CAPABLE OF REMOVING MUTUAL ELECTROMAGNETIC FIELD INTERFERENCE

摘要

PURPOSE: An antenna device embedded with an antenna for near field communication and a coil for transmitting wireless charging power is provided to mount a power transmission coil together in the same size as the antenna for near field communication.;CONSTITUTION: A pattern of an antenna for near field communication is formed at an outer part. A PCB(Printed Circuit Board) or an FPCB(Flexible Printed Circuit Board) has a wireless power transmission coil pattern. The wireless power transmission coil pattern is formed in an electrically mutual-insulation state as maintaining a separation distance equal to or above 2.0mm and equal to or below 9.0mm from the antenna in a remained inner area after an antenna pattern for near field communication is formed. The antenna for near field communication operates at a frequency of 13.56MHz.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Example for mounting a small coil for wireless charging in a near filed communication(NFC) antenna; (BB) Gap : 3mm; (CC) Coil for wireless charging power transmission; (DD) Near field communication antenna
