[0002] During the development of satellite antennas, it is necessary to test the performance parameters of satellite antennas in a microwave darkroom under the whole satellite environment in order to more accurately grasp the performance of the antenna under the whole satellite state. Generally, microwave darkrooms used to test satellite antennas have turntables for testing different azimuth and elevation angles, which can meet the test of satellite antennas under normal conditions. However, during the operation of actual satellites, the solar panels on the satellites will rotate. Different sailboard states will have different degrees of impact on the performance of the antenna on the sky. It can be seen that when you want to have a more detailed grasp of the performance of satellite antennas under different solar sailboard states, a satellite antenna test device that can simulate the rotation of the sailboard state is particularly important.
[0003] Currently, there are few common satellite antenna testing devices that can simulate solar panels for testing in different states, so it is impossible to conduct a full range of tests on satellite antennas, making it difficult to fully grasp the performance parameters of satellite antennas in all states during use.

Figure 5 , Figure 6 , Figure 7 The testing device of the utility model for testing the satellite antenna under different sailboard states also includes a sailboard connection panel 5, a sailboard rotating bearing 6, a shaft connection panel 7 and a sailboard angle locking screw 8; the shaft connection panel 7 is connected to the top of the simulated satellite body 1, the sailboard rotating bearing 6 is connected to the shaft connection panel 7, the sailboard rotating bearing 6 is connected to the sailboard connection panel 5, and the simulated solar sailboard 2 is vertically connected to the sailboard connection panel 5; a plurality of angle locking holes 51 are correspondingly provided on the sailboard connection panel 5 and the shaft connection panel 7, and the sailboard angle locking screw 8 is inserted into the angle locking hole 51 to lock the state of the simulated solar sailboard 2.
[0041] It should be noted that the sailboard connecting panel 5 is connected to the sailboard rotating bearing 6 through screws, the sailboard rotating bearing 6 is connected to the shaft connecting panel 7 through screws, and the shaft connecting panel 7 is fixedly connected to the simulated satellite body 1 through screws, thereby realizing the connection between the simulated sailboard 2 and the simulated satellite body 1 and the rotation function of the simulated solar sailboard 2.
[0042] For further information, see Appendix Figure 1 When the rotating shaft connection panel 7 makes the simulated solar sail panel 2 reach a certain test angle state, the sailboard angle locking screw 8 is inserted from the corresponding angle locking hole 51 of the sailboard connection panel 5 to the corresponding angle locking hole 51 of the rotating shaft connection panel 7, and the bottom surface of the rotating shaft connection panel 7 is tightened with a bolt to achieve the locking of the state of the simulated solar sail panel 2. The simulated solar sail panel 2 can rotate 360 degrees with the simulated satellite body 1, and the simulated solar sail panel 2 can be locked at each 15 degree rotation of the test state.
[0043] For further information, see Appendix Figure 1 The testing device of the utility model for testing the satellite antenna in different sailboard states also includes a support rod 9, a wire rope 100 and a hook 200, one end of the support rod 9 is connected to the simulated solar sailboard 2, and the other end of the support rod 9 is connected to the sailboard connection panel 5; one end of the wire rope 100 is connected to the side of the simulated solar sailboard 2 away from the simulated satellite body 1, and the other end of the wire rope 100 is connected to the sailboard connection panel 5 through the hook 200.
