1. A vehicle having antennas, the vehicle comprising:
a first substrate;
a second substrate spaced apart from the first substrate by a predetermined distance and having a ground layer;
a conical array antenna having cone radiators comprising a first cone radiator and a second cone radiator and arranged at predetermined distances, the cone radiators being disposed between the first substrate and the second substrate, having upper portions connected to the first substrate and lower portions connected to the second substrate, and provided with upper apertures, respectively;
a patch array radiator disposed on the first substrate and having metal patches disposed with being spaced apart from the upper apertures;
shorting pins configured to electrically connect the metal patches and a ground layer of the second substrate; and
a transceiver circuit configured to control a signal to be radiated through at least one of the conical array antennas,
wherein the metal patches comprise:
a first metal patch spaced apart from one side of the upper aperture of the first cone radiator; and
a second metal patch spaced apart from another side of the upper aperture of the second cone radiator,
wherein the first metal patch and the second metal patch are disposed between the first cone radiator and the second cone radiator, and
wherein an outer side of the first metal patch is spaced apart from an outer side of the second metal patch.
