COIL ASSEMBLY

The invention discloses a coil assembly, a coil assembly according to an embodiment of the present invention includes: a coil substrate having at least antenna coil patterns and wireless charging coilpatterns; and at least one auxiliary coil laminated on the coil substrate, and It has a spiral shape in which both ends of the auxiliary coil may be respectively connected to both ends of the spiral-shaped wiring of the coil pattern for wireless charging. Therefore, it is possible to prevent the coil pattern formed on the coil substrate from being unnecessarily thickly formed. 本发明公开种线圈组件，根据本发明的实施例的线圈组件包括：线圈基板，具有至少个天线用线圈图案和无线充电用线圈图案；及至少个辅助线圈，层叠布置于所述线圈基板，并具有螺旋形状，其中，所述辅助线圈的两端可以分别连接到所述无线充电用线圈图案的螺旋形排线的两端。因此，可以防止形成于线圈基板的线圈图案不必要地较厚地形成。
