<p>An antenna patch according to the present invention is an antenna patch which comprises a terminal unit used both for wireless charging and near field communication, is installed on a battery pack to perform wireless charging and near field communication functions, and comprises: a board member; a wireless charging antenna unit formed on the board member; a near field communication (NFC) antenna unit formed on the board member; a pair of wireless charging terminal units connected to the wireless charging antenna unit; and a pair of NFC terminal units connected to the NFC antenna unit. One of the wireless charging terminal units is characterized in being used as one of the NFC terminal units. According to the invention, terminal units for wireless charging and terminal units for NFC share a common terminal unit such that the number of terminal units is decreased, and an area occupied by the the terminal units is reduced to decrease a size of the antenna patch. Also, antenna patterns for wireless charging and NFC can be formed at both sides of the board member, thereby improving charging efficiency or NFC communication efficiency.</p> |
