Abstract

The present invention discloses a static shaping film reflector antenna based on a scissor-type truss structure. The static shaping film reflector antenna is composed of a scissor-type truss structure, a flexible cable, a basic cable net electrode, a thin film reflector and a static power supply. The scissor-type truss structure is configured to provide support for the whole structure, flexible cables are staggeringly arranged at the inner side of the scissor-type truss structure, the basic cable net electrode is connected with the scissor-type truss structure through the flexible cables, the thin film reflector is fixed on the basic cable net electrode and is connected and fixed with the scissor-type truss structure, and the static power supply is configured to provide high potential for the basic cable net electrode so as to provide grounding low potential for the thin film reflector. At folding, the flexible cables, the basic cable net electrode and the thin film reflector are folded in the free space of the scissor-type truss structure; and at unfolding, the flexible cables are tightened and are configured to support the basic cable net electrode, the thin film reflector forms the paraboloid shape under the action of the electrostatic force outputted by the static power supply. The static shaping film reflector antenna based on the scissor-type truss structure is small in the folding size and simple in structure, and can be used in the high-precision static shaping film reflector antenna.

Description

technical field [0001] The invention belongs to the technical field of satellite antennas, in particular to an electrostatically formed film reflector antenna based on a scissor truss structure in the field of satellite antennas, which can be applied to the design of high-precision electrostatically formed film reflector antennas. Background technique [0002] The rapid development of aerospace technology has put forward higher and higher requirements for spaceborne deployable antennas, mainly in two aspects: large aperture and high precision. Future communications, ground remote sensing and other fields also have potential demands for large-aperture, high-precision spaceborne antennas. At present, more mature space-borne reflector antennas, such as radial ribs, frame-type, peripheral truss and other mesh deployable reflector antennas, are difficult to meet the requirements of large aperture and high precision at the same time. For this reason, a variety of new concept ante...
