Novel fixed-surface deployable antenna structure

Abstract

The invention discloses a novel fixed-surface deployable antenna structure, and the structure is characterized in that the structure comprises a central disc base which has N sides which are arrangedto be a polygon; folding units which are circumferentially distributed in the circumferential direction of the central disc base, wherein the number of the folding units is N, and the folding units are hinged to each edge of the central disc base; each folding unit is composed of a first panel body, a second panel body and a third panel body, the first panel body and the second panel body intersect to form a first peak line, and the second panel body and the third panel body intersect to form a valley line; the first panel of one folding unit in two adjacent folding units is intersected with the third panel of the other folding unit to form a second peak line; and the extension lines of the first peak line, the valley line and the second peak line penetrate through the regular polygon corner of the central disc base. The fixed-surface deployable antenna structure has the advantages of simple integral device, light weight, high antenna storage rate, particularly high storage rate in theheight direction, simplicity in control and operation of the deploying process, capability of maintaining the deploying configuration of the antenna and the like.

Description

technical field [0001] The invention relates to the field of deployable antenna structure design, in particular to a novel solid surface deployable antenna structure driven by torsion springs. Background technique [0002] With the development of science and technology, the rapid growth of demand in communication, navigation, remote sensing and other fields has become more and more demanding for satellite information dissemination, and satellite information dissemination not only requires antennas to use high-frequency electromagnetic wave transmission, but also requires high-bandwidth, Excellent performance such as high gain and high signal-to-noise ratio requires the antenna to have a larger aperture and higher surface accuracy. However, due to the limitation of the volume of the fairing of the space vehicle, the antenna with a larger diameter must be folded to be stored in the satellite cover when the satellite is launched. The expandable antenna can be folded when the s...
