| Abstract;Large deployable on-board antenna structure will be necessary in future space missions such as advanced satellite communications. These large reflector structures must be lightweight and easy to stow, and they must have high surface accuracy. In order to meet these requirements, the authors have developed a large deployable modular antenna for the S-band that has mesh surface reflector. This modular mesh reflector consists of 14 modules and has an electrical aperture of more than 13m(15m in mechanical diameter). Seven modules were fabricated as prototypes. Through experiments with prototypes and analyses, the deployment characteristics were clarified. The authors also suggest simplified ground tests using only one module on deployment. (author abst.) |
