Abstract

The invention discloses an inflatable antenna and a preparation process thereof. The inflatable antenna comprises antenna units, wherein the antenna unit is a closed air bag, a reflecting layer is arranged in each antenna unit and is a paraboloid, the plurality of antenna units are subjected to array splicing, and are spliced to form a paraboloid-shaped reflecting surface, an antenna bottom support is fixedly connected below the antenna units, and an antenna bottom frame is arranged below the antenna bottom support and is an azimuth-pitch antenna seat or a six-connecting-rod-pitch antenna seat. According to the invention, an inflation structure is introduced into the middle of a traditional antenna surface supporting structure, and the auxiliary surface, namely the supporting mechanism ofthe auxiliary surface, also adopts a brand-new inflation structure to solve the problems of reflection surface shielding and heavy burden of the antenna pedestal, so that the auxiliary surface shielding problem is solved, the wave transmission rate of the auxiliary surface arm is good, the shielding area of the auxiliary surface arm is reduced compared with the original rigid support, and the antenna reflectivity is improved.

Description

Technical field [0001] The present invention relates to a phased array antenna, and more particularly relates to an inflatable antenna splicing. Background technique [0002] To meet the demand for the development of radio astronomy, the antenna aperture made larger, increasing the operating frequency, the antenna structure is also more complex, so that the large antenna structure more complex, heavier weight, limiting its diameter increases, the structure of a large antenna design has become a large antenna design process vital link. Large antenna designs are usually optimized for antenna mounts structure, improve the structural rigidity of the seat back frame antenna to meet the overall stiffness and tracking speed of the antenna. The presence of complex structure, large volume mass, and joints must have slip rings when the antenna is rotated continuously, and there is a tracking blind disadvantages of the conventional azimuth and elevation antenna base XY type antenna pedestal...
