This paper presents the mechanical and RF architectures of an 8-meter diameter multiple-band reflectarray antenna. Development of major components and aspects of the reflectarray antenna is also discussed. The most fundamental structural component of this reflectarray antenna is the Spring Tape Reinforced Aluminum Laminate Inflatable/Self- Rigidizable boom. The development of inflatable/self-rigidizable boom is an integrated part of our effort for developing the 8-meter multiple-band reflectarray antenna. Besides the inflatable/self-rigidizable boom technology, this paper also discusses other major technical challenges encountered in developing this reflectarray antenna, as well as technologies developed associated with these challenges. These technologies include double catenary for membrane tensioning, membrane flatness testing, spacing system for precisely separating membrane layers, multi-layer membrane fabrication process, and off-gravity system for studying the deployment process. In order to develop aforementioned technologies, several sub-scale engineering models have been assembled and the deployment of the antenna has been successfully demonstrated by this study. |
