1. An antenna system mounted in a vehicle, the system comprising:
a metal plate defining a part of the exterior of the antenna system, having a central portion and two side portions in one axial direction and operating as a radiator;
a lower substrate disposed under the metal plate;
a feeder disposed on a front surface of the lower substrate and configured to transmit a signal to the metal plate through a metal supporter;
a first antenna comprising a shorting pin configured to connect a ground of the lower substrate and the metal plate;
a second antenna disposed in the antenna system, separately from the first antenna; and
a transceiver circuit configured to control a signal to be radiated through at least one of the first antenna or the second antenna,
wherein a height from the lower substrate to the central portion of the metal plate is formed to be lower than a height from the lower substrate to at least one side portion of the metal plate.
