ANTENNA COIL TO BE MOUNTED ON SUBSTRATE AND ANTENNA DEVICE |
摘要 |
In an antenna coil (2) including a first magnetic core (4a), a second magnetic core (4b), and a flexible board (5), coil conductors are provided on a surface of the flexible board (5). By winding the flexible board (5) around the first magnetic core (4a) and the second magnetic core (4b), a first coil portion (2a) is formed around the first magnetic core (4a), and a second coil portion (2b) is formed around the second magnetic core (4b). The winding direction of the second coil portion (2b) is opposite to that of the first coil portion (2a). The first coil portion (2a) and the second coil portion (2b) are connected to form one coil as a whole. |
