Abstract: An antenna system for vehicle includes a vehicle and a MIMO antenna that is mounted on the vehicle and that transmits and receives radio waves of a predetermined frequency. The MIMO antenna includes antennas including a first antenna that mainly transmits and receives a first polarized wave and a second antenna that mainly transmits and receives a second polarized wave orthogonal to the first polarized wave, and the antennas are dispersedly arranged on the vehicle. One of the first antenna and the second antenna are arranged based on at least one of (1) a configuration in which one is arranged in a central region and another one is arranged in a first peripheral region or a second peripheral region and (2) a configuration in which one is arranged in a first region and another one is arranged in a second region.
