In a planar antenna device arranged in parallel, antenna rotation means 3 lit a b for making the planar antennas three-dimensionally rotatable are provided on each of the planar antennas 1, and each planar antenna 1 can be rotated independently. It was made freely possible. In the embodiment, the first antenna rotating means 3a for rotating each flat antenna 1 in the direction of the arrow A (for example, rotating within a vertical plane) is attached to the mounting frame 2 by a hinge 11. An L-shaped shaft support plate 12 rotatably supports a rotary shaft 10a that is rotatably attached and protrudes from one end of the flat antenna 1, and an arc-shaped shaft that protrudes from the mounting frame 2. A U-shaped id support plate 13 with an id hole 14 bored therein, and a rotating shaft 10b protruding from the other end of the flat antenna 1 are rotatably supported on the inner surface of the id support plate 13. A slider 15 that can move up and down along
The vertical 1119 bolt 17 screwed into the screw hole 16 of
The lower end of the vertical adjustment bolt 17 is interposed between a screw protrusion 18 protruding from the side surface of the slider 15 and inserted into the ID hole 14 and a protrusion 19 protruding from the ID support plate 13. The vertical adjustment bolt is composed of a coil spring 20 that biases the slider 15 in the direction of contacting the pedestal 2 and a fixing nut 21 screwed into the threaded protrusion 18, and whose tip abuts the mounting pedestal 2. By rotating the slider 17 and moving the slider 15 up and down along the side support plate 13, the flat antenna 1 is rotated in a vertical plane using the hinge 11 as a fulcrum, and the fixing nut 21 is tightened at an appropriate position. This prevents rotation in the vertical plane and makes it fixed. Next, the flat antenna 1
The second antenna rotation means 3b rotates the antenna in the direction of arrow B (for example, in the left-right direction) about rotation wheels 10a and 10b protruding from both ends. piece 22 , and the tip of the protruding piece 22 contacts the shaft support plate 10 .
