Description
Technical field
The invention belongs to space structure fields, are related to a kind of high storage ratio winding ribbed deployable antenna structure.
Background technique
In recent years, Small Satellite Technology development is swift and violent, wherein it is new to have developed to the space flight in functional application stage at initial stage in foreign countries
Mark also can be used in addition to having the advantages that develop the moonlets such as launch cost is low, the period is short in elegant cube satellite (CubeSat)
Standardization, modularized design, scalability is strong, and transmitting flexibly, can quickly networking.Cube satellite distributed three-dimensional system it is comprehensive at
This is low, high-efficient, can scout in terms of play a significant role, therefore its strategic value is higher.
Cube satellite antenna structure is based on unipole antenna.Unipole antenna gain is low, can if antenna gain can be improved
Greatly improve satellite communication quality.For cube satellite develop reflector antenna, can effectively increase antenna gain, can make its
X, the band operations such as S, greatly improve data transmission bauds, have high scientific research value and strategic value.
External cube satellite communication module is quickly grown.U.S. USC (University of Southern in 2012
California/Space Engineering Research Center) design cube satellite AENEAS successful launch,
Satellite antenna is radial rib paraboloid, and bore 0.5m stores volume 2U, and working frequency range is S-band；JPL has then started to research and develop work
Working frequency reaches the high-speed subminaturization high-gain aerial of 37.5GHz, and bore 0.5m stores volume 1.5U, and obtains 46dBi's
High-gain；Boeing winds rib reflector antenna in proposition microminiature in 2011, and bore 0.5m, service band is S-band,
Storage volume is then decreased to 0.5U, but the reflector antenna is only conceptual model, and type face precision is poor, and locking and method for releasing are not
It is bright.The research of domestic satellite antenna concentrates on heavy caliber reflector antenna, and the reflector antenna suitable for cube satellite is at present still
In the starting stage.Exploitation is suitable for the micromation high-gain reflecting surface Deployable antenna of cube satellite, compiles to cube satellite
Team's communication is of great significance.
Summary of the invention
