Claim:
1. An antenna system comprising: a case configured to be disposed on an upper surface of a vehicle body; a substrate disposed in the case and disposed along a longitudinal direction and a vertical direction of the vehicle body; an antenna configured for a first communication system and disposed on the substrate; an inside orthogonal antenna configured for a polarization diversity communication system used for a second communication system and disposed on the substrate such that a main radiation polarization plane of the inside orthogonal antenna is orthogonal to a main radiation polarization plane of the antenna for the first communication system; and an outside orthogonal antenna configured for the polarization diversity communication system and disposed outside the case such that a main radiation polarization plane of the outside orthogonal antenna is orthogonal to the main radiation polarization plane of the inside orthogonal antenna; wherein the outside orthogonal antenna is disposed apart from the case in the longitudinal direction of the vehicle body and extends only in a direction perpendicular to the inside orthogonal antenna; the antenna for the first communication system extends only in one direction; and the inside orthogonal antenna extends only in another direction, which is orthogonal to the one direction.
