Abstract

PURPOSE:To make it possible to miniaturize an antenna unit, and also to set antenna elevation small, by directing an antenna beam toward the direction, where the rotation directive region of the antenna main body is expanded, by switching. CONSTITUTION:Antenna beam 7a can be changed in direction to fornt direction A of antenna main body 7 held by mount 4 via antenna support pole 5 or direction B deviated by (thetao). Therefore, when support table 2 of shaking body 1 is positioned in the state shown by dotted lines owing to shaking so as to direct beam 7a of main body 7 in front direction A, beam 7a is charged in direction from A to B near its rotation limiting area and, in consequance, the expansion of the directive area of beam 7a by (thetao), namely, directing antenna elevation (theta) downward by (thetao) can be attained, so that the communication between a satellite under it and shaking body 1 can be made. At this time, since the radius of rotational trace 6 of main body 7, namely, the length of support pole 5 can be shortened, the antenna unit can be miniaturized.
