Problems solved by technology
Since the deviation value cannot be accurately predicted before the waveguide is installed, it is necessary to prepare gaskets of various thicknesses in advance. In actual assembly, only a small amount of gaskets is often used, and the excess gaskets will be wasted.
Whether it is a single shim or a combination of multiple shims, it can only compensate most of the deviations, and cannot accurately compensate all deviations
In addition, due to the need for multiple trial assemblies and measurement of deviation values, the operation is complicated and the assembly efficiency is low
[0005] Therefore, neither the method of adding a flexible waveguide to a conventional antenna support nor the method of adding a spacer to a conventional antenna support can solve the problem of waveguide length deviation well.

The invention discloses a waveguide length deviation adapted antenna connecting structure and method. An antenna support sleeves a waveguide and an antenna, kidney-shaped holes are uniformly distributed along the circumference of the antenna support, and a last waveguide segment is fixed to the antenna via first connecting screws. The antenna support is fixed on a spacecraft cabin plate via secondconnecting screws. Third connecting screws penetrate the kidney-shaped holes in the antenna support and reserved holes in the antenna successively from the outside to fix the antenna to the antenna support. The antenna support is simple in structure and convenient and reliable in installation, the kidney-shaped holes in the support adapt to and compensate the waveguide length deviation automatically, a soft waveguide and a pad are not needed any more, loss of a wave guide feed line is not increased, and the cost is low.
Description
technical field [0001] The invention relates to a structural device and method capable of automatically compensating for waveguide length deviations, and is especially suitable for compensating the length and dimension deviations of cabin-piercing waveguides on satellites and other spacecraft due to processing and assembly, so as to ensure reliable connection between the waveguide and the antenna, and the antenna Fixed and reliable. Background technique [0002] Compared with cables, waveguides have high transmission efficiency and high power withstand, and are widely used in the aerospace field. Usually, the waveguide is installed and fixed sequentially from the inside of the satellite and other spacecraft cabins to the outside of the cabin. Affected by the processing accuracy and assembly errors of the waveguide and the spacecraft cabin, the position of the last section of the outside waveguide connected to the antenna will deviate, affecting For the installation and fixa...
