Abstract

The invention provides an unfolding antenna basic unit, unfolding antenna and folding method based on origami. The invention relates to the field of aeronautical antennas, which solves the problems ofcomplicated deployment mechanical structure, small deployment area ratio and high cost of the traditional space deployable antenna structure. The invention comprises a shape memory material connecting piece, a heating device and a plurality of substrates. A shape memory material connector is used as a fold mark, and a heating device is arranged on the shape memory material connector, and the heating device is powered by a power supply. The expanded area of the basic unit of the expanded antenna is 4n times the folded area, n >= 1, n is an integer. The ratio of the unfolded area to the foldedarea is 4n, which can save the loading space to a great extent, thereby reducing the cost of aerospace emission. The plurality of unfolded antenna basic units of the invention can be combined and connected to realize different unfolded and folded area ratios. The invention is applicable to space launch.

Description

technical field [0001] The invention relates to the field of aerial antennas, in particular to a unfolded antenna basic unit, an unfolded antenna and a folding method. Background technique [0002] The rapid development of the aerospace industry puts forward higher and higher requirements for antennas. Due to the high power of the antenna required at present and the high transmission rate of data, the demand for large-aperture antennas is gradually increasing, and the space size of the vehicle is limited, so the structural form of the deployable antenna can be used to reduce the loading of the antenna Space, reduce the cost of launch. [0003] Most traditional space-deployable antenna structures use mechanical or inflatable deployment methods, which have problems such as complex deployment mechanical structure, small deployment area ratio, and high cost. Contents of the invention [0004] In order to solve the problems of complicated unfolding mechanical structure, small...
