The method for fixing the novel waveguide based on the satellite feed source comprises the following steps:
(1) determining an included angle between an antenna feed source and a satellite cabin plate according to the design task requirement of the antenna feed source;
(2) determining the number of feed source waveguides on an antenna feed source, and ensuring that a feed source waveguide port is parallel to an antenna feed source mounting surface;

The following is further illustrated with reference to specific examples:
the antenna feed is mounted on the satellite in an inclined manner, as shown in fig. 1, and forms a certain included angle with the whole satellite coordinate system of the satellite, which is mainly determined by the radiation coverage area of the satellite. In this case, when the waveguide is designed from the satellite load compartment, the coordinates are coincident with the whole satellite coordinates, in other words the waveguide is at an angle to the feed, and for the feed, especially a high throughput feed assembly, there are numerous waveguide ports and overlap each other. The reasonableness of the waveguide design depends on the fixed form and effect of the waveguide.
In this case, the waveguides must be designed in layers and columns. The first is to ensure that the waveguide can be designed within the size range of the body of the feed source (even if the size of the waveguide exceeds the size of the body, the size cannot exceed 100mm), otherwise, the waveguide can cause interference to other equipment; secondly, the number of waveguide layers is ensured to be as small as possible, as the number of waveguide layers is more, the height of the waveguide on the uppermost layer is higher, the response is larger in a mechanical test, and the potential risk is caused to the waveguide; and thirdly, the sizes of the layers and the columns of the waveguide are ensured to be consistent as much as possible, so that the uniformity and the replaceability are realized during the design of the waveguide support.
In the present embodiment, the angle between the feed source and the deck is first determined to determine the specific value of the non-90 ° waveguide, as shown in fig. 2. As can be seen from FIG. 2, the included angle between the feed source and the cabin plate is 167.235 degrees, the waveguide port of the feed source is parallel to the installation surface of the feed source, so the included angle between the waveguide port of the feed source and the loading cabin plate is 167.235 degrees, and the waveguide angle connecting the waveguide port of the feed source is 167.235 degrees. The specific design is shown in FIG. 3;
the rest design modes of the feed source waveguide port are consistent with the mode of the figure 3, and the three principles described above are met during design. The design completion effect is shown in fig. 4 and 5. From fig. 4 and 5 it can be seen that the waveguide spacing is 27mm, which can be matched in size modification for different antenna designs. The main purpose is to make the waveguide form the ranks and arrange, and the distribution is even, and the size is reasonable, makes things convenient for the design of support. The design of the first layer of the support is carried out based on the waveguide design, and the specific design form is shown in fig. 6. The first layer of supports shown in fig. 6 are adaptively designed according to the height and the size of the waveguide, so that the distance between the waveguide and the first layer of supports is kept consistent. As shown in fig. 7.
After the design of the first layer of support is finished, a second layer of support form needs to be designed, the design requirement of the second layer of support is high, and the second layer of support can play a role in fixing the first layer of waveguide and can also play a role in supporting the second layer of waveguide. The design form of the second layer bracket is shown in figures 8 and 9.
The interface of the first layer of support of butt joint will be considered in the design to the second layer of support, reserves the interface to the third layer of support simultaneously, makes things convenient for the installation of support. The design is continued according to the form, so that the waveguide bracket can be ensured to be completely fixed to the waveguide. The final design state is shown in fig. 10.
To verify that the support of the waveguide by the stent is sufficient, the form is reasonable. And carrying out relevant mechanical analysis on the waveguide support.
