ANTENNA COIL FOR MOUNTING ON SUBSTRATE AND ANTENNA DEVICE WITH SUCH ANTENNA COIL

摘要

An antenna coil (2) having a first magnetic core (4a), a second magnetic core (4b), and a flexible substrate (5). A coil conductor is formed on the surface of the flexible substrate (5). The flexible substrate (5) is wound around the first magnetic core (4a) and the second magnetic core (4b), and this forms a first coil section (2a) around the first magnetic core (4a) and a second coil section (2b) around the second magnetic core (4b). The second coil section (2b) is wound in the opposite direction to the first coil section (2a). The first coil section (2a) and the second coil section (2b) are interconnected, and these two coil sections as a whole form one coil.
