1. An antenna system mounted in a vehicle, the system comprising:
a radiator configured to transmit a signal applied through a lower aperture to an upper aperture;
a coupling patch disposed on an upper substrate to be spaced apart from the upper aperture so that the signal transmitted to the upper aperture is coupled;
a first antenna including a shorting bar connected in surface-contact with the coupling patch and configured to connect a ground layer of a lower substrate;
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 and the second antenna,
wherein the upper aperture and the lower aperture have a rectangular shape, and the radiator is configured as a pyramidal radiator in which the upper aperture is larger than the lower aperture in size, and
wherein the coupling patch has a rectangular shape.
