PURPOSE: A low frequency(LF) antenna for a vehicle is provided to omit a separate drying process with low pressure and low temperature injection molding, thereby reducing manufacturing unit costs of an LF antenna. CONSTITUTION: Ferrite(10) is formed by using a manganese-zinc system. The ferrite is inserted into an insertion hole formed in an internal case(20). An antenna coil(30) is wound on an external surface of the internal case at constant intervals. An external cable is electrically connected to the antenna coil and an external device. |
