<p><P>PROBLEM TO BE SOLVED: To provide a millimeter wave communication system or the like wherein an initial direction of a reflecting means located in a propagation path of a millimeter wave band signal can simply be adjusted even by one person. <P>SOLUTION: In the millimeter wave communication system 100, a millimeter wave transmitter 101 is provided with a light emitting means 15, and a millimeter wave receiver 102 is provided with a light receiving means 25 and a notifying means 26. A reflecting plate 103 for reflecting a signal wave and reflecting light is provided between the millimeter wave transmitter 101 and the millimeter wave receiver 102. In the case of adjusting an initial position of the reflecting plate 103, the angle of a transmission antenna 11 is adjusted so that a laser beam from the light emitting means strikes on the reflecting plate 103 and then the angle of the reflecting plate 103 is adjusted so that the laser beam reflected in the reflecting plate 103 strikes on a reception antenna 21. When the laser beam strikes on the reception antenna 21 in this case, the notice means 26 informs an operator about it. Finally, the reception antenna 21 is installed to be directed in a direction of the reflecting plate 103. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
