Embodiment Construction
[0030] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0031] refer to figure 1 , a preferred embodiment of the present invention provides an expandable solid surface reflective antenna, including a support mechanism 10 used as a support reference, used to control the solid surface reflective antenna to expand along the length direction and / or width direction and to switch the interference state The axial expansion assembly 20 of the reflector antenna and a plurality of strip-shaped solid-surface antennas 30 for combining to form a reflector antenna. In this embodiment, the strip-shaped solid-surface antenna 30 is used as a part of the reflector antenna, and there are 19 pieces in total. Those skilled in the art can understand that the number here...

The invention discloses a foldable fixed surface reflecting antenna. The foldable fixed surface reflecting antenna comprises a supporting mechanism used as a supporting benchmark, an axial unfolding assembly used for controlling the fixed surface reflecting antenna to be switched between unfolding and folding states in the length direction and / or the width direction, and multiple strip-shaped fixed surface antennas used for combining and forming the reflecting surface antenna; the axial unfolding assembly comprises an X-direction unfolding apparatus and a Y-direction unfolding apparatus; the supporting mechanism comprises a bracket assembly used for supporting the strip-shaped fixed surface antennas and a supporting base assembly used for driving the bracket assembly to move; the X-direction unfolding apparatus is connected with the supporting base assembly and used for driving the supporting base assembly to move in the length direction so as to unfold or fold the multiple strip-shaped fixed surface antennas in the length direction; and the Y-direction unfolding apparatus is connected with the bracket assembly and used for driving the bracket assembly to move in the width direction so as to unfold or fold the multiple strip-shaped fixed surface antennas in the width direction. The foldable fixed surface reflecting antenna disclosed in the invention can be folded ad compressed in the length and width directions and is low in accommodating rate, weight and cost.
Description
technical field [0001] The invention relates to the field of aerospace satellite communication, in particular, to a deployable solid-surface reflective antenna. Background technique [0002] With the wide application of satellite technology in mobile communication, radio astronomy, deep space exploration and space science, antennas are playing an increasingly important role. With the increase in the amount of transmitted information, large-aperture, high-precision antennas have become the development trend of antennas. In satellite communication, due to the limitation of the size of the fairing of the space vehicle and the consideration of reducing the cost as much as possible, the satellite antenna must be designed to have an expandable / foldable structure—that is, when the satellite is in the launch phase, the antenna needs to It is folded and folded to reduce its size so that it can be placed in the fairing, and when the satellite enters the predetermined space orbit, the...
