Claim 0:
1. An antenna system mounted on a vehicle, the antenna system comprising:
a feeding part formed on a front surface of an antenna board;
a dielectric carrier disposed on a rear surface of the antenna board; and
a radiator part formed on the dielectric carrier;
wherein the radiator part comprises:
a main radiator formed on a rear surface of the dielectric carrier and configured to be electrically connected to the feeding part; and
a parasitic radiator formed on the rear surface of the dielectric carrier and formed to be spaced a predetermined distance apart from the main radiator so that a signal from the main radiator is gap-coupled,
wherein the parasitic radiator is electrically connected to a ground of the antenna board through a ground connection part, the main radiator operates in a first mode, and the parasitic radiator can operate in a second mode.
