More Information
Summary:The present invention provides a coil module which can improve a tag recognition rate, and can improve near field communication (NFC) performance. The coil module comprises: a substrate; an input/output terminal part formed on the substrate; and a coil for NFC formed on at least one surface of the substrate, and connected to the input/output terminal part. The coil for NFC includes: a first pattern part having one end which is connected to the input/output terminal part and is formed to be rotated in one direction on the substrate; a second pattern part connected to the first pattern part, and crossing an inner side region of the first pattern part so as to divide the inner side region of the first pattern part into at least two parts; and a third pattern part having one end which is connected to the second pattern part, and having the other end which is connected to the input/output terminal part. 기판과, 상기 기판에 형성되는 입출력 단자부 및 상기 기판의 적어도 일면에 형성되며 상기 입출력 단자부에 연결되는 NFC용 코일을 포함하며, 상기 NFC용 코일은 일단이 상기 입출력 단자부에 연결되고 상기 기판에 일방향으로 회전되도록 형성되는 제1 패턴부와, 상기 제1 패턴부에 연결되어 상기 제1 패턴부의 내측 영역을 적어도 두 부분으로 나누도록 상기 제1 패턴부의 내측 영역을 가로지르는 제2 패턴부 및 일단이 상기 제2 패턴부에 연결되며 타단이 상기 입출력 단자부에 연결되도록 형성되는 제3 패턴부를 구비하는 코일 모듈이 개시된다.
