Abstract (in Japanese) (See Japanese page) 
(in English) In fifth generation mobile communications system (5G), 28 GHz band is used and the application for cellular-V2X using 5G has been actively investigated. In this paper, we proposed the distributed vehicle glass mounted antenna system that directional antennas are installed on all windows. By using this, the omni-directional antenna pattern and high antenna gain is achieved. We clarified that the proper 28GHz antenna position for the vehicle based on the evaluation results using proposed distributed antenna system. From the results, we confirmed that the reception characteristics and throughput were improved in the proposed configuration that the main beam direction of vertical and horizontal polarization antenna is alternately installed than conventional localized antenna system.
