1. An antenna system mounted on a vehicle comprising:
a first circuit board configured to be mountable to a metal frame;
a second circuit board disposed so as to be spaced apart a predetermined distance from the first circuit board through metal supporters;
a feed structure configured to connect between the first circuit board and the second circuit board; and
an antenna configured to radiate a signal transmitted from a feed structure, the signal being transmitted through a space between the first circuit board and the second circuit board,
wherein the feed structure comprises:
a first signal pad and a second signal pad spaced a predetermined distance apart from each other in an area on the first circuit board from which a ground area is removed; and
a metal post connected to at least one of the first signal pad and the second signal pad and vertically formed between the first circuit board and the second circuit board.
