Abstract: An antenna system mounted on a vehicle, according to the present specification, is provided. The antenna system can include: a main radiator formed on an antenna board and configured to be electrically connected to a feeding part; and a parasitic radiator formed to be spaced a predetermined distance apart from the main radiator so that a signal from the main radiator is gap-coupled. The parasitic radiator is electrically connected to a ground through a ground connection part, the main radiator operates in a first mode, and the parasitic radiator can operate in a second mode.
