[0020] The utility model will be further described below in conjunction with the drawings, but the protection scope of the utility model is not limited to following described.

[0021] As Figures 1-4 Shown, a kind of phased array airborne antenna, including antenna body 1, rotary table 2, adapter plate 3 and mounting plate 4.Adapter plate 3 is rotatably installed on rotary table 2 by rotating assembly, so that adapter plate 3 can rotate with rotating assembly, mounting plate 4 is slidably connected to adapter plate 3 and is detachably connected with adapter plate 3 by loose screw 5, mounting plate 4 is equipped with fixed plate 1, and antenna body 1 is fixedly connected with fixed plate 1 by screw and the like connecting piece.

[0022] As Figure 2As shown, the rotating assembly comprises an adjusting motor, the mounting seat 6 and the ear plates 7, the adjusting motor is installed in the rotating table 2, the mounting seat 6 is fixedly connected with the ear plates on both sides, the two ear plates are rotatably connected with the rotating table 2 on both sides through rotating shafts respectively, the rotating shaft on one side of the rotating table 2 is connected with the output end of the adjusting motor, and the adapter plate 3 is fixed on the mounting seat 6 through screws or other connecting members. The adjusting motor drives the mounting seat 6 to rotate, and then the angle adjustment of the antenna body is realized.

[0023] As shown in Figure 1 , Figure 3 , Figure 5 As shown, the bottom of the mounting plate 4 is provided with a groove 8 matched with the adapter plate 3, the side walls on both sides of the groove 8 are provided with sliding grooves 9, and the sliding rails 10 matched with the groove 8 are fixed on both sides of the adapter plate 3. The loose screw 5 is arranged on the mounting plate 4, the adapter plate 3 is matched with the groove 8 at the same time, the mounting plate 4 is pushed from one end of the adapter plate 3 to the other end of the adapter plate 3, then the sliding rails 10 are matched with the sliding grooves 9, and then the mounting plate 4 and the adapter plate 3 are fixed together through the loose screw 5.
