PURPOSE: To obtain image information of high quality with a fixed station by transmitting by radio the information of a mobile station from a plane antenna adjacent to a mobile station antenna to the fixed station. CONSTITUTION: This plane multi-antenna 10 is constituted by arranging a large number of plane unit antennas 1 and coupling them in planar shape. The antennas 1 are arranged on a shield grounding plate 14 at prescribed intervals. Also, the bar shape mobile antenna 21 of the mobile station 20 in a remote controlled unmanned self-traveling vehicle is provided approximating to the antenna 10, and the image-picked up video of a television camera 22 is frequency-modulated by a transmitter 23, and outputted from the antenna 21, and it is received by the fixed station via the antenna 10. Since the antennas 21, 10 are adjacently arranged and the information is transmitted by radio, fading phenomenon, signal turbulence due to phase shift or the deterioration in the S/N between transmission and reception antennas can be reduced even when multipath and a standing wave due to reflection are generated, therefore, video information of wide band width with high quality can be obtained irrespective of the position of the mobile station 20. |
